Akatsuki Blitzkampf

Akatsuki EN-Eins (アカツキ/エンアイン) is a series of Japanese dōjin 2D fighting games, developed by the dōjin circle SUBTLE STYLE for Microsoft Windows and arcades. It takes place in an alternate 21 century in the year 200X - 20XX, but with a World War II era aesthetic.

Akatsuki
The initial game in the series had three major revisions: Akatsuki Shisei Ichigō, Akatsuki Blitzkampf, and ''Akatsuki Blitzkampf Ausf. Achse''.

Akatsuki Shisei Ichigō (アカツキ試製一號) is the first installment of the series, which was released in November 2003 for Microsoft Windows. As the game itself has no storyline, it is a prototype version of Akatsuki Blitzkampf, below.

Akatsuki Blitzkampf (アカツキ電光戦記) is a full version of Akatsuki Shisei Ichigō for Microsoft Windows, including additional characters, game modes and online play.

Akatsuki Blitzkampf Ausf. Achse (アカツキ電光戦記 Ausf. Achse) is the final standalone revision of the first game for arcade and Microsoft Windows. After finding success on the Dōjin soft scene, on September 27, 2007, Monthly Arcadia magazine confirmed that the game would be launched as an arcade title, with the provisional name "Akatsuki Blitzkampf AC", published by SUBTLE STYLE itself. The first location test was held on November 23, 2007, at High Tech Land Sega AViON in Japan. It features improved graphical enhancements and re-introduces a new character known as Perfecti (Kanzensha in Japan), who was originally a mere alternate version/palette swap of Mycale in the original Blitzkampf. The final release of ''Ausf. Achse'' was in Japanese arcades on February 20, 2008, for the Sega NAOMI system and published with the help of PIC company. Although ''Ausf. Achse'' being announced on March 29, 2019, to have a Microsoft Windows port, under the name Akatsuki Blitzkampf Type-A (アカツキ電光戦記 A式), the COVID-19 pandemic cause the release date and development to be delayed.

It is a common misconception that the subtitle is a misspelling of the German phrase "Auf Achse," meaning "on tour/on the road/on the move". In fact, the term "Ausf." is short for "Ausführung" and has been very common in historic German military nomenclature, meaning "option model" or "version". Therefore, "Ausf. Achse" literally means "option model with axle(s)" or "moveable/mobile/non-stationary version". "Achse" also translates to "axis", and given the game's militaristic style, a very probable translation is "Akatsuki Flash Fight Axis Edition".

EN-Eins
The sequel to the first game and its updates has itself had two revisions: EN-Eins Perfektewelt and EN-Eins Perfektewelt Anastasis.

EN-Eins Perfektewelt (エヌアイン完全世界) is a sequel to ''Akatsuki Blitzkampf Ausf. Achse'', co-developed between Subtle Style and Rutubo Game Works and released in arcades. It was released on the System Board Y2 arcade system on June 25, 2010. The game was later ported to the Taito Type X² arcade board and released digitally via NESiCAxLive on February 22, 2012.

The subtitle comes from the German phrase "Perfekte Welt," meaning "Perfect World", referring to the new titular protagonist EN-Eins, the last surviving clone of his cloning batch who aims to defeat one of Knights Templar’s leaders, such as Valkyria (a boss version of her playable clone, Tempelritter) for the sake of creating a perfect world. The game also re-introduces Mycale's replacement and former host, Kati as a playable character, as well introducing Anonym-Guard as a replacement for Anonym Merel Lambuth.

EN-Eins Perfektewelt Anastasis (エヌアイン完全世界 ANASTASIS) is an updated version of the sequel game, developed and published by Subtle Style. It was first released on NESiCAxLive arcade digital for the game's NESiCAxLive port's 10th-anniversary debut and to celebrate NESiCAxLive's 12th anniversary.

The subtitle comes from the Greek word "Anastasis," meaning "rebirth", which also represents Subtle Style's return to game development since the series appeared in certain games crossed over. As the series' creator Subtle confirm that the original release was in fact in the beta stage, this update, being an actual finalized version of the original release, not only adds completely re-worked artwork, UI, and an arcade storyline, it re-introduces Mycale in the body of Anonym Merel Lambuth which she stole at the end of the previous game and a playable version of Valkyria, as well as introduces a new character who is a motorcyclist Blitzsoldier known by the name Inazuma. Apart from the new version of Mycale and playable Valkyria, 2 unknown brand new characters (a second new playable character and the true final boss (planned to be initially non-playable) were part of the crowdfunding however, the two latter's inclusions did not meet the funding's stretch goal for its full release plan by the time the funding ends.

The crowdfunding held by Subtle Style and its sponsored arcade center KO-HATSU for the new contents within Anastasis first started on April 26, 2022, until June 5, 2022. Game Center Will opened a tournament charity event of original EN-Eins Perfektewelt on May 29, 2022, to support the crowdfunding before the end of the funding date.

At the same time the official website opened on November 11, 2022, the location test was only for November 25 until 27, 2022 at the arcade centers Ko-Hatsu (Osaka), Game Center Will (Tokyo), Maxim Hero (Hokkaido), and Fantasista (Okayama) prefecture, before its initial launch. Originally, the game’s initial release was meant to be released at the end of 2022. However, on December 5, 2022, Ko-Hatsu and Subtle Style confirmed that the release date would be delayed to around 2023, in order to fix various gameplay issues based on the location test’s data. Following its wide arcade release in late February 2023, a proper full version of the game which includes crowdfunded playable characters and finalized contents is in the works, with the release date having yet to be revealed.

Gameplay
The game's playstyle is regarded as relatively "old school" in comparison to many other dōjin fighter releases such as Melty Blood, Eternal Fighter Zero, or Big Bang Beat, as many of the systems and conventions in the game are rather similar to several late 1990s fighting games made by companies such as Capcom. The game is slower-paced and focuses more on careful footwork and space control than the aforementioned games. The extra modes the game provides and the ways in which they are unlocked also resemble console releases of old fighting games, further reinforcing the retro feel. A signature feature of the series is the Reflector, a reversal-parry move that allows players to guard against incoming attacks without taking chip damages or cost guard gauge, and can only counterattack at close range, whether on the ground (both standing or crouching) or in the air.

In EN-Eins, the Reflector button (B+C) can also be assigned to the D button for beginner-friendly use. When activating a burst-like move known as Perfektewelt by pressing A+B+D, the game will grant the player increased boosts, such as health regeneration, at the cost of no longer being able to use EX or regular Super moves once this state has been entered. Once the gauge limit of Perfektewelt depletes, players cannot use EX or regular Supers until the regular gauge returns to being usable in the following round(s). While in the Perfektewelt state before reaching the gauge limit, players can press A+B+D again to perform an Instant Kill-like attack while in close proximity, the "Perfekte Finish". EN-Eins also introduces a double jump-like air dashes, auto combos, and dash attacks.

The co-op-based modes does not appear in ''Akatsuki Blitzkampf Ausf. Achse's arcade version and the original EN-Eins Perfektewelt, with the former’s said port because of its arcade board game space limitations, while the latter was a beta like Akatsuki Shisei Ichigo''. While the original Akatsuki Blitzkampf has both 2-on-2-based Team Battle Versus and a non-canonical Arcade mode which can be played by 1 - 4 players, the full version release of EN-Eins Perfektewelt Anastasis only has 2-on-1-based Dramatic Battle like in the Street Fighter series, but it follows the storyline of the first player who starts playing the game.

Synopsis
Akatsuki EN-Eins is set in an alternate Japanese Imperial year, Koki 266X A.D. (200X AD in a Gregorian year) up to 20XX AD, involving several characters that resemble the Nazis and soldiers of the World War II era and a bit from both Mediterranean and Scandinavian myths, among others. In-game visuals supplement this sort of specific militaristic theme and environment, portrayed by the flat and somewhat cubist character portraits and story sequence images. Akatsuki Blitzkampf (Ausf. Achse) is also the finalized version of its 2003 beta title Akatsuki Shisei Ichigō, involving many characters from the game. The series’ plot heavily focuses on unearthing ancient surroundings (mainly sourced from a hollowed Earth located at Agartha beneath Tibet and a fictional Neuland beneath Antarctica), reincarnations, cloning and godhood.

In 195X, Imperial Army high-class technical engineer Akatsuki is transporting a new weapon, the "Blitz Motor", from Germany to Japan, when his submarine is damaged. Akatsuki is able to survive by using a Hibernation Unit to remain frozen in the submarine for 50 years. Later, in 200X AD, the submarine suddenly emerges in the Arctic Ocean. Akatsuki begins to carry out his final orders received during the war, which were to destroy the Blitz Motor to prevent it falling into enemy hands. However, various organizations begin to search for Akatsuki in order to gain the power of the Blitz Motor for themselves.

EN-Eins storyline takes place around ten years after Murakumo's defeat at the hands of Akatsuki. In 20XX AD, there was a small report of a collapse accident in the undeveloped Tibetan Tsampo Canyon. With Murakumo's fall from leadership, this allows the ancient witch Mycale and her partner, the battle maiden Valkyria an opportunity to take over "Gesellschaft" (German for "society") assets. A few months later, the world's chaos starts due to the simultaneous global terrorist attack by an organization claiming to be the "Neu Tempera Orden" (German for "New Orders of Knights Templar"), the one secretly leading and end up revealing themselves as the organization's originator under the front name "Perfecti Cult". Taking on this chaos, a dark fight for the hegemony of the new world begins.

Introduced in Akatsuki Shisei Ichigō

 * Akatsuki (アカツキ)
 * High-class technical officer of the Imperial army and one of the former Gesellschaft members. Believed to have died in the Arctic oceans at a critical time after the war came to an end, during the transportation of a new military unit from an allied country. Fifty years later, he returns alive and unchanged in appearance. Now wielding superhuman abilities powered by the original prototype Blitz Motor, he resumes his mission. He soon learns that his last mission during an imperial day was set up by his superior, Murakumo to have himself supposedly killed, but the plan fails as Akatsuki survives and awakens fifty years later. As Murakumo is the original Akatsuki before him and Akatsuki was the first successful Blitz Motor super-soldier known as a Blitzsoldier, Akatsuki is referred to by his former superior and the rest like Fritz and even Kanae as "Prototyp 1", with Akatsuki's real name being unknown. After killing Murakumo's original body with the help of Kanae, Marilyn and Wei, Akatsuki is likely indirectly free a young soldier named EN-Eins from his stasis before escaping from Gesellschaft's destruction. He and EN-Eins share a similar reason, destruction of Gesellschaft and its originator, the Tempera Orden. A few years later, while being targeted by the Tempera Orden who are now in possession of the remaining Gesellschaft assets, Akatsuki set to return to Antarctica, believed to be the main source of Blitz technologies in the underground world.
 * He also appeared in Under Night In-Birth (starting from Exe:Late until Sys:Celes) and BlazBlue: Cross Tag Battle patch 2.0, in which the former game series takes place between his venture at Shanghai and prior to his encounter with both Kanae and Fritz at Fuji during his titular game's storyline, while the latter crossover game takes place after his and EN-Eins's titular games.

 * Mycale (ミュカレ)
 * A French witch of falling moon from an ancient time that belongs to a secret religious society called "Neu Tempera Orden" (originally known as an unnamed "Perfecti Cult"); in 1253, they have been manipulating history from behind the scenes and she was planning to wipe out old humanity under "Operation Dynamis" since Middle Age until the Holy Club interfered and had her original body was burned alive in public for her villainy. Thankfully, inspired by Praeses Valkyria's Heilige Lanze, Mycale used the black magic and learned its attributes to link her soul to her weapon Dainsleif, under its sealed marshal wand appearance, and be able to possess a host's body when one of them touches it. She was part of the Gesellschaft alliance during World War II before her host's body from that time was killed by Adler, sometimes after Akatsuki Zero (now Murakumo) sabotaged Akatsuki's submarine in the 1950s. Upon possessing the young Kati in the present, she manipulates her host's parents and is able to avoid Sai's suspicion, in order to further her plans to recover the missing weapons. However, she has to deal with disposing Murakumo over their leadership on leading Gesellschaft, using anyone else's desires, such as Marilyn's ambitions to overthrow Black Hand's leadership from Yin Hu to quickly succeed her plan and obtaining a Blitz Motor from Akatsuki to become a next leader of the triad, then disposing of them as well. Although Mycale is separated from Kati by a Holy Club member Anonym Merel Lambuth, the nun ends up possessed by the witch's soul when she holds the Dainsleif containing the former's soul. While her first "form" is replaced by her spiritual replacement and former host, Kati in the sequel game, EN-Eins Perfektewelt, while her second "form", which possessed Merel's body dubbed Mycale-A (tentatively spelled Mycale A.) is playable in the Anastasis update, where the latter will be added sometime after Q1 2024.
 * There were multiple choices between wearing her glasses or not while possessing Merel's body based on the crowdfunding supporters' choice via comments on Ko-Hatsu's Ci-En account in the first fifteen days of September 2022 for her "new form"'s inclusion in Anastasis. Despite the final poll result on September 21, 2022 where Mycale-A would fight with her glasses on in the final release, the first day of October 2022 reveals a version without wearing her glasses will be included as well, and one of the two versions will act as alternative EX color row.

Despite his original body was killed by Akatsuki, Kanae, Marilyn and Wei, he revealed to have some of his clones to be used as his vessel to keep him alive, namely Senke (his current host, and Kanae's superior), and Yin Hu (Black Hand's late-leader who was killed by Marilyn sent by Mycale). Aside ruling G.S.O.D and Black Hand behind the scene, Xinhua Computers was also his sub-organization he ruled, until is its infiltrated by his old nemesis, Sai. While in Senke's body at the time Mycale has all Gesellschaft's assets back to Tempera Order, and declare a war alongside Valkyria on humanity, Murakumo remains to manipulate the government systems while trying to get the assets for his own godhood goal back. He was also involved in the creation of Inazuma, before the latter escape, but resurfaced sometimes later when the Tempera Orden wages war on humanity.

Introduced in Akatsuki Blitzkampf Ausf. Achse

 * Perfecti (Kanzensha in Japan)
 * While Perfecti is commonly a moniker of those who sought to achieve a perfect immortality, whether through body possession or reincarnations, the playable Perfecti in this series is an ultimate form of the witch Mycale, equipped with a different type of Blitzkamp Motor than Adler and his Elektrosoldat unit. She can transform her Dainsleif from its sealed marshal wand state into a Devil Blade bayonet. She was originally a mere palette swap of Mycale in Akatsuki Blitzkampf prior to being re-introduced in Ausf. Achse update as her own character and the second round's sub-boss of the said update after defeating Mycale.

Introduced in EN-Eins Perfektewelt

 * EN-Eins (エンアイン) (full name: Energaia Eins (エネルゲイア・アイン))
 * The sole survivor of Gesellschaft's Energaia cloning batch cloned from an unnamed Neuland God, yet inherit the bloodline of another discovered ancient civilization, Neuland. He is presumably indirectly saved by Akatsuki before Gesellschaft is destroyed after Akatsuki killed Murakumo's original body, with EN-Eins already escaped from the base during the said battle. He received the powers of Energaia due to being used for experiments by the Gesellschaft to achieve godhood and destroy the old humanity. EN-Eins aims to stop the evil military organization to avenge his clone "siblings" and save humanity. Unbeknownst to him, he is not the only survivor of his batch.

 * Kati (カチィ)
 * The former host of Mycale in Akatsuki-title games after the latter possessed the body of the Holy Church member, Anonym Merel Lambuth. As Kati is now freed from Mycale, she becomes her own as a playable character. Kati was born in Germany and raised in Shanghai, China, where her parents are associated with Sai, her first and only known friend. Unknown to her during her time after being freed from Mycale's possession, it was likely that Anonym Merel saved her life at cost of being possessed by Mycale. Once Kati unexpectedly awaken at Tsampo Valley, Tibet, she found a morningstar wand called "Wand of Evil Eye: Morgenstern", and learns that Sai was the one who gave it to her for her own protection. The morningstar she wields holds a dangerous power that may curse its user with its eye. Thankfully, Kati is taught by Sai to be immune to the staff's curse with both index and pinky fingers holding up. Despite Mycale committing unforgivable crimes (including using Kati's body as her previous host), Kati still views her as a friend, due to being lonely like her.

 * Anonym-Guard (アノニミ・ガード)
 * The Anonym Merel's replacement, after her disappearance and being possessed by Mycale. She is an elite palace guard of the Holy Club who begin to search for her and freed her from Mycale's possession.

 * Tempelritter (テンペルリッター)
 * The female clones of Valkyria, who resemble Nazi Valkyries serving as the Neu Tempera Orden's foot soldiers like Elektrosoldat. Furthermore, Tempelritter's creation also directly comes from a genetic template of Valkyria's current host, Mitford, who was an early clone of Tempelritter batch. Despite having an unstable bloodlust when it reaches too far as the main flaws, they are still warriors at heart.

 * Valkyria (ヴァルキュリア)
 * A self-proclaimed destroyer of the world who is both ancient Battle Maiden and a grandmaster (dubbed Praeses) of Neu Tempera Orden. After her soul was sealed inside the Heilige Lanze, at some point during the beginning of World War II, a prototype clone of Unity Mitford called "Mitford" stumbled upon the lance and touches it. However, Mitford committed a suicide by shooting her own head to prevent Valkyria from possessing her. Unfortunately, the lance already fused with Mitford's body, as her soul ceased to exist, Valkyria's soul becomes dormant and heal Mitford's corpse. While possibly being an inspiration of Mycale's Dainsleif on having similar host possession attributes, Valkyria's Heilige Lanze cannot be easily removed from her host, due to the lance fuses with the host body and can be summon from a thin air. Sometimes later, like Adler, she also have let herself be cloned to mass-produce Tempelritter army, similar to Adler's Elektrosoldat. She briefly appeared as part of Perfecti's Reflector moves in Akatsuki-titles, until properly she made her debut in the sequel EN-Eins. In the original version of the second game, she was simply a power-up palette swap final boss version of Tempelritter, such as can use EX/Super gauge moves infinitely, even after “Perfektewelt” state being used and was highly recommended for the players to prepare a Reflector against her. Later being re-introduced as a fully playable balanced character in 1.10 update of the second game's update title, Anastasis, to differentiate herself from her clone's moveset.

Introduced in EN-Eins Perfektewelt Anastasis

 * Inazuma (イナズマ) (real name: Energaia Neun (エネルゲイア・ノイン), or EN-Neun (エヌノイン) for short)
 * Tentatively under an unidentified Blitzsoldier generic name. A mysterious unidentified Type-1 Blitzsoldier who rides the weaponized one seated motorcycle-like Elektromagnetisch Tracked Vehicle, and is thought to be the robotic counterparts of Akatsuki. He was originally found unused in the original version of EN-Eins as an incomplete character. Based on his designs and move sets, Inazuma is a homage to Kamen Riders. Inazuma's origin begins when Murakumo (now possessing Senke's body after Akatsuki, Kanae, Marilyn and Wei killed the previous body) took over the Land Research Institute's development. In reality, he was once known a ninth Energaia clone, the other surviving member his nearly extinct cloning batch besides EN-Eins, having been experimented by Murakumo to be equipped with Type-1 Blitz tech. By the time EN-Neun becomes Inazuma, he immediately escapes from Murakumo and discarded his former name, off-screen, until he resurface from the shadow few years later where the Neu Tempera Orden wages war against humanity.

 * 2 unnamed characters were originally planned through the crowdfunding stretch goal for their initial inclusion in this game’s full launch, with the second fighter originally set to be a non-playable true final boss of the updated game. However, in the end, the crowdfunding did not meet its goals for their inclusions in the updated game, by the time the crowdfunding ends, leaving their fates unknown.

Development
The founder of the dōjin circle Subtle Style, known as 'Subtle', had previously worked for a video game company helping develop numerous fighting games. After leaving the company in April 2000, Subtle founded Subtle Style and began development of Akatsuki Shisei Ichigō as a prototype first entry to the series. Shisei Ichigo released in November 2003 for Microsoft Windows, and would later receive a finalized version under the title Akatsuki Blitzkampf on April 30, 2007. Following the success of Blitzkampf, Subtle Style shifted to a focus on Arcades, and released the arcade-only update title ''Akatsuki Blitzkampf Ausf. Achse'', powered by Sega NAOMI and published by PIC on February 28, 2008.

Subtle later produced a sequel to ''Akatsuki Blitzkampf Ausf. Achse, known as EN-Eins Perfektewelt'', featuring a new protagonist and updated gameplay. The initial release was published by Rutubo Games Work exclusively in the Japanese arcade, first on the SYSTEM BOARD Y 2 on June 25, 2010, before being released digitally via NESiCAxLive on February 22, 2012. The series was put on hiatus as Subtle became a recurring freelance sprite artist for French Bread. This resulted in Akatsuki appearing as a guest character in French Bread's game Under Night In-Birth, and then through French Bread's relationship with Arc System Works, appearing again in BlazBlue: Cross Tag Battle. These guest appearances brought a new recognition of the Akatsuki EN-Eins series, particularly to unfamiliar Western audiences.

On March 26, 2019, it was revealed on Subtle Style's blog that ''Akatsuki Blitzkampf Ausf. Achse'' would be ported to Microsoft Windows, though it was subsequently delayed due to the emergence of the COVID-19 pandemic, leaving the release date unknown. Subtle Style has since been asked about a possible Steam release.

Ten years after the release of its NESICAxLive arcade port, just as the COVID-19 pandemic progressively decrease of Japanese arcade marketing, EN-Eins Perfektewelt received a finalized version under the title EN-Eins Perfektewelt Anastasis. The crowdfunding for the development of Anastasis ran from April 26, 2022, until June 5, 2022. Additionally, the crowdfunding was supported by a charity tournament of original EN-Eins Perfektewelt at Gamecenter on May 29, 2022. On July 18, 2022, Subtle Style and Ko-Hatsu revealed through the latter's Ci-En e-mail account that they chose NESICAxLive as the primary arcade platform for EN-Eins Perfektewelt Anastasis in response to the decrease of arcades and arcade cabinet manufacturers. At the same date, Ko-Hatsu confirmed that the current development on July is at 70%, planning, at the time, to be released in December 2022. However, the release date have been delayed to around 2023, due to last month’s climate, and ongoing COVID-19 pandemic.

Reception
The first game in the series, Akatsuki Shisei Ichigō, received mixed reviews from reviewers, who praised the gameplay and art of the game but criticized the small amount characters (3 characters at launch, 5 after being patched) and various gameplay issues. Its finalized version titled Akatsuki Blitzkampf added new characters, backgrounds, and game modes, as well as added online play and further deepened the combat system. Akatsuki Blitzkampf has a strong community in Japan with tournaments and ranking battles in arcade centers like Ko-Hatsu. Outside of Japan communities have formed on websites such as Shoryuken.com (the official host of the Evolution Championship Series fighting game tournaments in the US).
