Plot
Two years have passed since the EL-Diver Incident, an event that almost destroyed the Gunpla Battle Nexus Online (GBN) game until it was resolved by the force group known as "Build Divers", and soon after more EL-Divers were discovered. In order to make the game more secure, a newer version of the game was rolled out in order to prevent the same incident from happening again and with newer experiences that would make the gameplay more immersive to players.

The story focuses on Hiroto Kuga, a high schooler who is a rogue mercenary Gunpla Diver in GBN, who goes in the game and wanders throughout its countless dimensions while helping out other Divers whether it is on insistence or by hire. Despite his selfless act, he chooses to remain unaffiliated with anyone and refuses rewards and Force (Diver parties) group invites, isolating himself from other people even in real life.

His primary goal as a Diver is to be reunited with a mysterious girl from his past named Eve, who was in fact the very first EL-Diver to appear in the game. But after a special request mission, Hiroto is united with three other active Divers in a strange world named "Eldora" and forms the Force group "BUILD DiVERS" in what appears to be just another GBN gamespace event, until they learn the truth about Eldora and its consequences not only for GBN, but for the entire world.

BUILD DiVERS

 * Hiroto Kuga (クガ・ヒロト) / Hiroto (ヒロト)
 * The main protagonist of the series and a high-school builder, veteran diver, and a former ace member of the Force group Avalon, who lives in Yokohama. He was one of the first minors to make it to the deep end of GBN, due to his conviction of being a person who does his best to help others. He was active prior and during the events of the previous series.  Now working as a rogue diver for hire after leaving Avalon, he wanders the GBN gamespace alone, harboring regrets, resentments, and suffering from trauma after the death of his close friend and lover, the EL-Diver Eve. He is very calm and a man of few words, usually refusing others' reward and help, especially on joining other forces, but this stoic persona is a mental mask to hide his condition from everyone, including his parents. But when a special mission done by Freddie united him with Kazami, May and Parviz, they accidentally formed the force team named "BUILD DiVERS" to protect the Eldorans from the One-Eyes army. Currently he is the ace of his unit and the leader of the overall force.
 * Hiroto uses the PFF-X7 Core Gundam as his main Gunpla, based on the RX-78-2 Gundam from the original Mobile Suit Gundam series. Its special armament system called the "core-change" gimmick and his first theme invented from that gimmick is the "Planets System". This allows the Core Gundam to be equipped with various types of armor and weapons, each for a different situation named after the eight planets. Hiroto later upgrades his Gunpla into the PFF-X7II Core Gundam II. This new Core Gundam can transform into the "Core Flyer", in a similar fashion to the original Gundam's FF-X7 Core Fighter for increased mobility and like its predecessor, it can also use the Planets System:

This new Core Gundam can transform into the "Core Flyer", in a similar fashion to the original Gundam's FF-X7 Core Fighter for increased mobility and like its predecessor, it can also use the Planets System:


 * Earth Armor (PFF-X7/E3 Earthree Gundam): Core Gundam's default blue armor, focused on traditional all-around combat.
 * Mars Armor (PFF-X7/M4 Marsfour Gundam): A red armor whose focus is on fragments of four styles of close combat, hence "Cross-Combat".
 * Venus Armor (PFF-X7/V2 Veetwo Gundam): A green armor whose focus is commando style ranged and bombardment combat, additionally with option works.
 * Mercury Armor (PFF-X7/M1 Mercuone Gundam): A navy armor whose focus is underwater combat.
 * Jupiter Armor (PFF-X7/J5 Jupitive Gundam): A white armor whose focus is fast orbital combat.
 * Uranus Armor (PFF-X7II/U7 Uraven Gundam): An indigo armor focused on reconnaissance and high powered sniping.
 * Saturn Armor (PFF-X7II/S6 Saturnix Gundam): An orange armor focused in demolition style close combat without beam weapons, originally developed to counter Gundam Frames.
 * Neptune Armor (PFF-X7II/N8 Nepteight Gundam): An aqua-green armor equipped with a customized Volture Lumiere system similar to the one from Mobile Suit Gundam SEED C.E. 73: Stargazer, intended to be used for traveling through GBN's space in a short amount of time, but was used for launching into orbit instead of maneuvering in deep space. It is ultimately discarded in Eldora's orbit due to the strain of leaving Eldora's gravitational field.
 * Pluto Armor (PFF-X7II+/P9 Plutine Gundam ): Appearing only on Gundam Build Metaverse, the black colored armor is used for close combat and dueling purposes with its color scheme reminiscent of that of EcoPla.
 * PFF-X7II/BUILD DiVERS Re:Rising Gundam: A special combination of the Core Gundam II with the WoDom Pod + and parts from the Gundam Aegis Knight and the EX Valkylander, armed with two giant beam sabers, eight miracle wings born from Eve's blessings, and the "Grand Cross Cannon", Hiroto's first special move, made with the help of his team.
 * In one occasion, Hiroto changes his avatar to a Haro to pilot the Mobile Builder Haro Loader to help with the repairs on Cuadorn by making a prosthetic wing out of gunpla parts. During the Gunpla Battle Royal, he pilots an unmodified ASW-G-08 Gundam Barbatos Lupus Rex from Mobile Suit Gundam: Iron-Blooded Orphans.
 * In Battlelogue, it is revealed that he has made a second Core Gundam II that he leaves on Eldora with the colors of the Gundam MK-II Titan. Another variant of this Gunpla sports the old "Gundam G3" colors with his team's personal crest, which is most likely to represent Sarah since the color of her hair, eyes, and dress embody Hiroto's time with Eve before they joined Avalon and to symbolize how he has officially befriended the original Build Divers. Each of the two units have unique advancements, the Titan color specializes in ground and underwater combat and the G3 color specializes in aerial and space combat.


 * May (メイ)
 * A seemingly late teens female diver who prefers to play solo, she is a very calm and no-nonsense girl whose interest is in battles alone. However, she is not a fan of those who engage their opponents head on and prefers to implement a strategic approach. She is mature and has a strong sense of justice, and can be impulsive rushing into situations, especially for those in danger. Later in the series, she is revealed to be one of the 87 EL-Divers, however she was not one of those who were saved after the EL-Diver incident two years ago, she was born shortly after. After she was born she was given her own Mobile Doll body similar to Sarah, that is when she first met her, Koichi, Tsukasa, and Nanami. During the Lotus Challenge Eldoran style rehearsal battle it is revealed that she, as a new sister of Sarah, addresses the latter as the older since Sarah is chronologically older, regardless of her maturity. In the final episode, she is revealed to have been born with the remnant data originating from Eve, the first born EL-Diver who Hiroto befriended and fell in love with several years ago, and carries Eve's earring on her armband. In Battlelogue, it's implied that she is currently living with Hiroto IRL and in GBN is his attendant.
 * May uses the JMA0530-MAY WoDom Pod as her main Gunpla, which is a customized JMA-0530 Walking Dome from Turn A Gundam. In the later episodes, the mobile suit is revealed to be a disguise for its true form, the HER-SELF Mobile Doll May. May later upgrades her WoDom Pod into the JMA0530-MAYBD WoDom Pod +. During the Gunpla Battle Royal, she uses her Mobile Doll (albeit with a new color scheme and the Gundam Base logo) along with an unmodified NZ-999 II Neo Zeong mobile armor from Mobile Suit Gundam Narrative.

 * Kazami Torimachi (トリマチ・カザミ) / Kazami (カザミ)
 * A diver who was a former member of the diver group "Mu Dish". He is a very energetic diver who fancies himself as a hero and seeks to make a name for himself in GBN. Though he enjoys the game, he also has been a long fan of the G-TUBER Captain Zeon on his success in several battles, but this obsession drove his former teammates to losing and soon left the group. It was at that time he met Hiroto and the others to form the new BUILD DiVERS group to prove his sense of justice, and be the leader of their team, although he doesn't mind Hiroto being the team's ace and hero. In real life, Kazami is a teenager with a scrawny body and the son of a fisherman. Currently he is the leader of the latter unit, the left hand sub-leader of the overall force and the poster guy for their G-tube channel.
 * Kazami uses ZGMF-X19AK Gundam Justice Knight as his main Gunpla, which is a ZGMF-X19A Infinite Justice from Mobile Suit Gundam SEED Destiny customized with knight motif and limited armament. He also possesses a modified Petit'gguy called the Justi'gguy. Kazami later uses the GAT-X303K Gundam Aegis Knight as his main Gunpla, inspired from the GAT-X303 Aegis Gundam from Mobile Suit Gundam SEED, which is also customized with knight motif and limited armament, especially its larger shield that can combine with its other weapons to form the bigger "Keraunos Hyper Beam Sword", when it assumes "King Mode" and a transformable Assault Mode similar to the original Aegis. During the Gunpla Battle Royal, he pilots an unmodified ZGMF-X42S Destiny Gundam also from SEED Destiny.

 * Patrick Alexandre Leonard Arge (パトリック・アレクサンドル・レオナルド・アルジェ) / Parviz (パルヴィーズ)
 * A novice diver and builder whose avatar has fox-like features, inspired from being the younger brother of Shahryar, one of the characters of the previous series. He usually takes on playing the game after taking advice from his older brother, but due to his shy and often timid personality, thus had problems making friends. In real life, Patrick is a teenage foreigner from a wealthy Middle Eastern family, just like his brother. He was left paralyzed after his glider crashed in the middle of a storm; said incident caused him to have a fear of heights, even though he doesn't want to be and eventually breaks through it.
 * Parviz uses the Valkylander, which he nicknamed "Morgiana", as his main Gunpla, a customized Super Deformed GNY-001F Gundam Astraea Type-F with elements from the Gundlander series in which first appears as a dragon and can transform into its SD Mobile Suit form when in battle. On some occasions, it carries the "Avalanche Rex Buster", a cannon which can also combine with the Gunpla itself. It also has its own version of the Trans-Am system from the 00 series called "Gundrans-Am". Parviz later makes another version his Gunpla called the EX Valkylander, based on the GNY-001 Gundam Astraea and its design elements based on the Sacred Beast Cuadorn, including bigger wings for itself and the Re:Rising Gundam where they grow into miracle wings. In one occasion, Parviz changes his avatar to a Haro to pilot the Mobile Builder Haro Fitter to help with the repairs on Cuadorn. During the Gunpla Battle Royal, he pilots an unmodified version of the XXXG-00W0 Wing Gundam Zero from Gundam Wing: Endless Waltz.

In the final episode, she joins GBN as a new member of Hiroto's team and meets Freddie along with the New Eldorans. Her diver avatar is a shrine priestess in a dress miko.
 * The only known gunpla she has is a pink Petit'gguy that she built with Hiroto's supervision from back when they were in elementary school.

People of Eldora

 * Freddie (フレディ)
 * A preteen anthropomorphic dog boy who lived on Planet Eldora, considered to be one of the "New People" after the departure of the Ancients eons ago. He is very cheerful and shows a lot of respect to the BUILD DiVERS, often calling them Creators. He is also the one who can summon them through the temples left behind by the Ancients. He saw many of the Build Divers' accomplishments on the GBN live stream via the ruins and would go to the ruins everyday just to watch them. He originally planned to use the ruins to summon the original Build Divers, but ended up making a new team of Build Divers instead, and initially thought they were part of them, with two of the members, Hiroto and May, having a connection to Sarah and one, Parviz, having an indirect connection to her. Like Sarah, he usually rides in a Gunpla as a passenger, mostly with Hiroto. He initially served as the BUILD DiVERS' motivator, but is now the Eldoran representative member of the team and later on the entire Build Diver force. It is revealed that his ancient ancestral genes came from a dog that belonged to one of Alus's creators whose face Eve merited.

 * Cuadorn (クアドルン)
 * A giant biomechanical dragon that existed in the Legends of Eldora for centuries. Once created by the Ancients, he helped them with protecting Eldora from outside threats eons ago until they decided to depart from space to search for new planets to colonize. He soon fell into a deep sleep, watching over the "New People" that flourished the planet after the Ancients' departure. After Masaki stumbled into Eldora, he assisted him with fighting against the One-Eyes until it was injured. Since then, it took refuge in Milagg Mountain until it was awakened once more by Freddie and Parviz to help Hiroto and May repel back Alus's attack against them. Reluctant to accept the BUILD DiVERS' help at first, Cuadorn agrees to ally with them after realizing their will to protect their friends in Eldora. Cuadorn's wing is later restored with some spare Gunpla parts provided by Parviz, with the beast later joining the BUILD DiVERS on their mission to rescue Masaki. He and Masaki later assist the BUILD DiVERS in destroying Alus' satellite cannon and, upon its destruction, destroy its mainframe to prevent Alus from retreating back to Eldora. After the final battle, Cuadorn is seen with some New Eldorans on Milagg Mountain which was relocated in the crater where Seguri City once stood.

One-Eyes

 * Masaki Shido (シドー・マサキ) / Masked Man (仮面の男) / Sid (シド)
 * A veteran S-Ranked Diver who May has been searching for since his disappearance. In real life, Masaki is bed-ridden at the city's general hospital after falling into a coma while logged in to GBN half a year prior to the events of the series. Later, it is revealed that he is brainwashed by the One-Eyes, becoming a masked man who served Alus and sided with them to terrorize Eldora. May recognized him as such despite his appearance in Eldora. However, his extended time in Eldora plus the brainwashing from the One-Eyes caused a serious deterioration on his real life self and his health condition. But due to the BUILD DiVERS' efforts, Masaki is freed from Alus' control and returns to his body back in the real world. With his sister's consent, Masaki returns to Eldora and teams up with Cuadorn again to assist the BUILD DiVERS in the final battle against Alus. He and Cuadorn later destroy the satellite cannon's mainframe to prevent Alus from returning to Eldora.
 * Masaki uses the MSF-007TE Gundam Tertium as his main Gunpla, a heavily customized MSF-007 Gundam Mark-III from Z-MSV. After being brainwashed by Alus, his Gunpla is converted into the MSF-007SS Gundam Seltsam equipped with the massive Seltsam Arm, which gives the Gunpla a demonic look while displaying massive strength. After Masaki is finally released from Alus's control, his Gunpla is converted into the Gundam Advanced Tertium, now equipped with the Tertium Arms for space combat.

 * Alus (アルス)
 * The series's main antagonist, an Artificial Intelligence entity residing in Eldora's moon which was created by the Ancients to protect the planet from outside threats. After the Ancients left the ravaged planet after a long war, Alus entered into a long slumber. Once he reawakened, he mistook the current inhabitants of Eldora for invaders and started attacking them, using his vast knowledge and resources. After having his orbital cannon and mobile units destroyed by the BUILD DiVERS, he angrily decided to invade GBN as a last resort to destroy them, the game and all Divers in it. In the end, he and his entire fleet, alongside his mobile suits, were defeated and sank down by the BUILD DiVERS, the Third Coalition of Volunteers and many other Divers in GBN, with Alus being deleted by both Hiroto and Riku, during which, he passes on after seeing a vision of two Ancient Eldorans resembling Eve and Sarah. After the final battle, his feelings and some of his data are reincarnated as an infant EL-Diver carrying a pendant resembling a Guard Eye, making him the 88th EL-Diver.
 * Due to Alus's vast access to GBN through Masaki, he was able to create and build mechanical puppets based on Gunpla seen in GBN Online. In the second season, Alus develops the AGP-X1 Alus Core Gundam, a more powerful replica of Hiroto Kuga's Core Gundam with more upgraded specifications and weaponry to fight the BUILD DiVERS. It utilizes a similar core-change gimmick like the original Core Gundam, allowing it to be equipped with several armors made by Alus himself.

Due to Hiroto's nightmare in his back story and why she kept her Pet, Mol, close, the latter knew of Eve, but didn't know who she was to her. Nevertheless, she was very touched by Hiroto's kindness for thanking Riku for saving her, finishing Eve's will, holding no grudge against the Build Divers, and knowing she had an older sister who went so far for her, even had the man she loved be the one to do it. Later on it is revealed that she along with Eve merited the faces of two of Alus's creators. Currently, Hiroto continues to view her as Eve's younger sister and May's sister.

Her existence also caused glitch bugs in the game, but small ones that were not that harmful.

Before the events of the battle between the original Build Divers and the second Coalition of Volunteers, she pleaded with Hiroto to mercifully sacrifice her using the Core Gundam and promise to her that he will still be the same caring person to help others in need, especially her sister, also mentioning that she would only pass on into GBN's Sea of Data. Despite his plead to stop her, she ended up a sacrifice right before Hiroto's eyes and her form faded out of existence. This incident traumatized Hiroto greatly, leaving him with permanent emotional open wounds. He felt that clinging to Sarah for the rest of his life would help him move on to the point that led him to blame Riku and the Build Divers before ultimately sparing him in order to save Sarah's life and leaving Avalon to become a rouge diver, but kept a vow to never blame Sarah. In the final episode, May, another EL-Diver whom Hiroto teamed up with, is revealed to be born with some lingering remnants of her lost data, sporting her earring on her armband, which she wore under her jacket the whole time. Hiroto finally has closure but continues to view her has all the Build Divers' true Goddess of Victory, with Hinata as her priestess.
