List of I Got a Cheat Skill in Another World and Became Unrivaled in the Real World, Too characters

This is a list of characters for the light novel, manga and anime series I Got a Cheat Skill in Another World and Became Unrivaled in the Real World, Too.

Main characters

 * Yūya Tenjō (天上 優夜)
 * The main protagonist, he was tormented by both his classmates and his family for his ugliness and obesity. He inherits his grandfather's house, where he finds a portal to another world. After killing a powerful monster using the weapons he found in the house, Yūya grows stronger, taller and handsome, and obtains special powers by defeating enemies like in a video game. Because his previous isolation made him a loner and shut-in, he is both very self-depreciative about his enhancements and quite ignorant of the effects they - especially his new, improved looks and charisma - have on his environment. He travels back and forth between both worlds, using his newly obtained skills to improve himself, gaining a lot of notoriety and making friends and enemies along the way.

 * Night (ナイト)
 * A puppy of the Black Fenrir, a mythological race of disastrously destructive canines in the other world, who was found and adopted by Yūya during one of his outings in the Forest of Weald. Like Yūya, he levels up when confronting monsters in combat, and grows stronger and smarter than his small size would suggest. After fighting the alien Dragonians, he gains the ability to assume his mature form at night, thereby vastly increasing his fighting power. He is named after the kanji for "night" (夜) in Yūya's first name.

 * Akatsuki (アカツキ)
 * A young Mōju boar from the other world who joins Yūya as his second pet. A naturally born protector of his homeworld, Akatsuki has several innate holy powers (including abilities to heal, purify an area, and perform exorcisms) which are strong enough to defy even a Vile's powers. Yūya has named him for his red fur, which reminds him of the scarlet hue of the sky just before dawn.

 * Ōma (オーマ)
 * A purple-scaled member of the Genesis Dragons, a legendary species of only two which existed in the other world since its creation. Originally a guardian of evil, he gradually shifted towards good. He befriended the Sage after the latter defeated him in combat. Millenia later, he awoke from his slumber due to the recently increased activities of the Saints and Evils, inadvertently causing unrest among the local monsters. After Owen asks Yūya to investigate the disturbance, Yūya, Kaori and Yuty come upon the dragon, who in spite of his arrogance allows himself to be "tamed" after developing a liking to Yūya's cooking. He also gains the ability to shrink himself from his normal giant size to a more miniature form thanks to a drop item gifted to him by Yūya. Despite all this, however, he mostly lazes around, rarely lending a helping hand. Yūya gave him his name after a word for "early evening" based on a Japanese expression saying "bad things come at dusk".


 * Kuro (黒)
 * A sentient dark essence originally infused with Yuti by the Evil Trio to corrupt her. When its influence is suppressed by Akatsuki and Yuti subsequently devotes her life to combatting the Evils, the essence abandons her body and tries to kill her. To save Yuti, Yūya allows the essence to possess him, but once inside Yūya, it found him too pure and kindhearted to take him over. Accepting its situation, it keeps residing in Yūya, acting as a catalyst for him to tap into his inner dark side to channel the powers the Evils use without becoming truly evil. Unless it is needed, Kuro either "sleeps" or likes to make snide remarks at Yūya's expense.


 * Ciel (シエル)
 * A young Luan fledgling meant to act as a celestial guide for Yūya. Its egg was sent to him after he has elevated to a special holy rank. Like a Phoenix, it rises again if killed, stronger than before, and can bestow this ability to its allies as well. It was named by Yūya after the French word for "sky" owing to its blue plumage.


 * Stella (ステラ)
 * A white Dimension Cat that Yūya and Meiko encounter during a trip in the space of the Between World. Like any creature capable of existing in that place, she bears an innate Power of Existence, which is capable of injuring even beings with divine powers.

Ōsei Academy

 * Kaori Hōjō (宝城 佳織)
 * Daughter of the chairman of the prestigious Ōsei Academy and a student council member. She takes an interest in Yūya when he tries his best to defend her from some thugs before his transformation. When she meets him again after having done a thorough background check, Kaori invites Yūya to study at Ōsei with her, and he accepts. She becomes a close friend at school and develops romantic feelings for him; she is also the first person Yūya confides in about his secret access to the other world. With her curiosity and sense for adventure aroused, she begins accompanying him on his forays, levelling up like him and developing a special talent at diplomacy.

 * Yūya's homeroom teacher at Ōsei Academy.

Her father, Ginji Sawada, runs a small eatery near the Hōjō family's beach vacation house, where she has to help out at times as a waitress.

Tenjō family

 * Grandpa (お祖父さん) / Yūnosuke Tenjō (天上 祐之助)
 * Yūya's recently deceased grandfather who was the only person in Yūya's family to treat him with kindness. His loving support is Yūya's moral anchor in his decisions to help people in need. In secret, he was also a frequent traveler to Argena, the other world, although unlike Yūya he could only reach it in spirit form through a spell developed by the Sage. Yūya later encounters his grandfather during a trip into the Underworld and, upon his insistence, takes Meiko into his household.

 * Kūya Tenjō (天上 空也)
 * One of Yūya's ancestors, a powerful sorcerer and monster-slayer from the Heian Period. It was his legacy of harboring spiritual energy in his body which was responsible for Yūya's physical deformations before his levelling up. To help combat monsters and demons should any of them reappear on Earth, he sealed his spirit inside a scroll which was in Yūnosuke's collection, but returns to Earth as a spirit after the border to the Underworld is accidentally brought down, releasing some of its denizens into the world of the living. After discovering that Yūya has inherited his powers, he starts training him in their use.


 * Yōta Tenjō (天上 陽太) and Sora Tenjō (天上 空)
 * Yūya's twin brother and sister, and his juniors by a year. Because of their (compared to their brother) far better looks, they have been far more favored by their parents, leading them to adopt the same spiteful superiority against their older brother. After Kaori invites Yūya to Ōsei, they hire the Red Ogre Gang for a raid against the school, but after Yūya defeats them all, the Ogres' leader tries to kill them in revenge. They are rescued by Yūya; however, leaving them in deep shame over their past behavior towards him.

 * Iris Knowblade (アイリス・ノウブレード) Sword Saint (剣聖)
 * A peach-haired female Saint who has recently taken up residence in the kingdom of Regal, and the mightiest fighter among the Saints. A member of a noble house, she was more interested in the art of sword-fighting than becoming a "proper" noble lady, and became the apprentice of the former Sword Saint. She is approaching her 27th year, and because she has devoted so much time to her fighting skills, she despairs over not having found a suitable husband.

After Quarro is killed by Yūya, he kills the third member of the triumvirate in order to absorb his power and add it to what he has collected from killing other Evils and Saints to gain more power to destroy Yūya.


 * Quarro
 * A member of the Evil Trio, and the Evil of Death, with the appearance of a young human boy. He is the first of his group to challenge Yūya, but is killed by him.


 * Shu Zakuren / Katana Saint
 * A male samurai-like warrior who lost his family to a band of rampaging beasts and was taken in by the former Katana Saint. His main goal in life is eliminating all evil influences disrupting order on Argena. After attaining divine powers, he and other like-minded Saints have decided to take total control of all humans on Argena, thereby upsetting the balance between good and evil that Argena strives to maintain. However, he is defeated by Yūya and Stella.


 * Gilbert Fister / Fist Saint
 * A male Fallen Saint and supreme master of fist-fighting. Arrogant and blood-thirsty, he let himself be infected by the Evil Trio's dark influence and went off to kill his former fellow Saints. After viciously beating Usagi, he has to contend with Yūya, who, enraged by his teacher's battering, unleashes his inner dark side for the first time, thereby gaining the power to easily defeat the Fist Saint. As Fist runs off vowing revenge, he is intercepted and devoured by Ōma.

Others

 * The Cult of Evil
 * A band of fanatical worshippers of the Evils, particularly Avis. After Avis is defeated by Yūya, they seek revenge on him by summoning the Lord of Evil from the past, but accidentally also sending Yūya back in time, where he meets the still-living Sage. They are collaterally obliterated when Ōma fights the Lord of Evil in the present.

Argena

 * Argena
 * The living soul of the other world which resides in its molten core. She is an old friend of Ōma and Yūnosuke Tenjō, Yūya's grandfather. She is also aware of everything going on in her world, and is the one who appoints the Saints and bestows them with their special powers to maintain the balance between good and evil. For this reason, she further enhances Yūya's abilities to wield both holy and dark powers with ease.


 * Lord of Evil (イヴィル)
 * The ultimate lord of the Evils who once fought Zenovis. During their climactic battle in the past, Evil suddenly switched places with Yūya when the Cult of Evil used one of Zenovis' own spells to bring the Lord of Evil into the present. However, after Zenovis trains Yūya in the proper use of his powers and he is sent back to his own time, Yūya ends up mortally wounding the Lord of Evil, who then shifts back to the past and is finished off by Zenovis.

Upper Planes

 * The Observers
 * A pantheon of primordial divine beings who created most of the life in the universe. Earth and the world of Argena, however, developed on their own and are therefore out of their sphere of influence. They later recruit Yūya and his friends among Argena's Saints to bestow them with the power needed to combat the False God.


 * Lanael
 * A female angel with a blonde bobcut and blue eyes. She is a messenger of the Observers and Zenovis', and later Yūya's, contact with the divine realms.


 * The False Gods
 * Faceless evil entities wielding the power of emptiness, a greater power than even the Observers. One of them is defeated after Yūya, Yuti, Usagi, Iris and Odis are recruited and empowered by the Observers to destroy him, but while passing into the Underworld just before disspiating, it inadvertently destroys the barriers between the Underworld and the world of the living.


 * The False Dragon
 * The second of two Genesis Dragons who was originally aligned to the side of good, but because of Argena's need to balance good and evil (because one side cannot exist solely without the other), he fell to the dark side and became a servant of evil, earning him the titulation Sentinel of the False God. He lived in the time of Zenovis, the legendary Sage, and was killed by Yūya when he got stranded in the past and after Zenovis summoned the Dragon to train Yūya in the instinctive use of his full abilities.

Lower Planes

 * Reimei (霊冥)
 * The Queen of the Underworld, who bears the form of a little human girl. When the boundaries between her realm and the world of the living are penetrated by the False God's displacement into the Underworld following his defeat, allowing some souls of the evil dead to escape. After learning how Yūya defeated the False God, she asks him to come into the Underworld to keep a very dangerous prisoner in check.


 * Meiko (メイコ)
 * Meiko is a creature in the form of a black-haired human girl, born as the embodiment of all the malice from countless evil souls interred in the Underworld, but innocent and kind in her heart. Knowing the destructiveness of the power inside her, she willingly had herself sealed away. When the False God defeated by Yūya inadvertently disables the seals holding her in the Underworld, causing her power to go out of control, Yūya is asked by Reimei to restore the seal. But upon the suggestion of Yūnosuke Tenjō and Reimei, who are convinced that she means no harm, Yūya instead absorbs all the spiritual energy from her, thereby creating a soul link with her, and takes her into his household, where she has taken up the role of a servant.


 * Ikkaku (一角)
 * A blue-skinned oni and Reimei's chief servant.

The Between World

 * Yin
 * An outcast who was banished from his birthworld into the space of Between World, but survived thanks to his innate Power of Existence and found the power to control reality to some extend, usually for consuming existing worlds and creating new ones. He is also responsible for forcing an alternate version of Yūya - one who never levelled up but was taught the use of his innate spiritual power - into his servitude until the alternate Yūya sacrifices his life to save his other self. He has set his sights on consuming Yūya's Earth so he can create another world for him and his kind to live on. But when he tries to make Yūya his new pawn, Yūya instead drains the Power of Existence from him, weakening him to the point of fatal vulnerability.


 * Veda
 * Another outcast in the Between World, and Yin's cohort. After Yin's defeat, he is destroyed by Meiko and Stella.

Aliens

 * Merl (メルル)
 * An extraterrestial girl who originates from the planet Amel, whose inhabitants are human-like but feature phosphorescent skin and hair, use memory-manipulating and nanotechnology, and are familiar with the concept of magic. She arrives on Earth looking for the blueprints for a weapon system, meant to fend off her people's ancient enemies, the Dragonians, in a digital storage unit, which Yūya's grandfather found and kept with his other artifacts and which Ōma unwittingly activated. Unfortunately, this also causes an invasion of the Dragonians against Earth, which prompts Merl to offer Yūya her assistence in return for him helping her people. After the invasion of Amel is thwarted, Merl enrols at Ōsei Academy at her father's bidding to get Yūya's genes, but she also genuinely falls in love with him, which makes her mission even more complicated.


 * Draco III
 * King of the Dragonians, an aggressive alien species and an ancient enemy of the Amelians who employ instant cloning to overwhelm their opponents with superior numbers.


 * Drade
 * Commander of the Dragonian army's Third Division.


 * Marl (マール)
 * Merl's father. After Yūya frees his planet from the besieging Dragonians, he intends for him to stay on their world to gain control of a giant golem the Sage had left near Amel in order to safeguard their world. Failing that, he tasks Merl with obtaining Yūya's genes by bearing his child.
