Undead Unluck

Fuuko Izumo (出雲 風子, Izumo Fūko)

Voiced by: Moe Kahara[2]

An 18-year-old girl who teams up with Andy. When she was a kid, her Negator ability awakened and she accidentally killed her parents, along with other people, in a plane crash. As such, she became severely asocial out of fear of harming others with her ability, becoming suicidal until meeting Andy. Her Negator ability, "Unluck" causes whoever touches her skin-to-skin to die after losing all of their luck. Following the events of the Ragnarok arc, she becomes the new leader of the Union in the 101st loop.

Andy (アンディ, Andi)

Voiced by: Yuichi Nakamura[2]

A suicidal and reckless man who teams up with Fuuko. He is obsessed with finding a way to kill himself and takes an interest in Fuuko for her Unluck ability. His Negator ability "Undead" prevents him from dying and he can use his regenerative abilities to do a multitude of things, such as firing his finger like a bullet. He has a card in his head that, when removed, releases a second personality called Victhor. A running gag is his clothes being destroyed, as he can not regenerate them, but this stopped when he tames the UMA Clothes. It is later revealed that Andy is one of the only people aware of the loop, as his powers means he does not die when the world is reset.

Juiz (ジュイス, Juisu)

Voiced by: Mariya Ise[3]

The leader and founder of the Union along with Victor. Her Negator ability "Unjustice" allows her to force targets to enact the opposite of their sense of "justice" by looking at them. She has tamed the UMA Move, which is the Union's main mode of transportation. After the Unbelievable arc, she reveals that the world is stuck in a time loop and she keeps her memories by using an artifact called the "Ark," and has lived for millions of years accompanied by Victor so that they may finally kill God. Fuuko replaces her as leader of the Union for the final loop.

Shen Xiang (シェン＝シアン, Shen Shian)

Voiced by: Natsuki Hanae[4]

A Chinese martial artist who is very perky. His former Negator ability, "Untruth" allowed him to make his targets do the opposite of what they intended to, so long as he was looking at them with at least one eye and was fond of them. He also carries a "Nyon-Kinko Staff" artifact which can extend and contract long enough to reach space, as well as a rideable cloud named Kinto-Un. After his battle with his master resulted in his death, Mui used an artifact to revive him as a Jiangshi, losing his Negator abilities but keeping his natural martial arts skills.

Mui (ムイ)

Voiced by: Yui Ishikawa[5]

Shen's subordinate. Before the Union's battle with Feng, Shen's master, she was Shen's assistant. Though she has no ability, she makes up for it by using Artifacts and Martial Arts. After Shen's death, "Untruth" was transferred to her.

Tatiana (タチアナ, Tachiana)

Voiced by: Rie Kugimiya[3]

A young Russian girl who cares for her teammates greatly. When she gained her Negator ability, her powers accidentally destroyed her home, killing her parents. She was to be sold on the black market, before being saved by Billy. She lives in a spherical robot suit, and her Negator ability "Untouchable" creates a powerful barrier around her, although she always has a hole open around her mouth to eat through.

Top Bull Sparx (トップ＝ブル＝スパークス, Toppu Buru Supākusu)

Voiced by: Nobuhiko Okamoto[3]

A short-tempered Brazilian 15-year old. His Negator ability "Unstoppable" grants him super speed if he attempts to slow down once he reaches a certain speed, and his body must undergo a significant change in shape for him to stop, such as suffering a heavy injury. In the past, he was a poor boy who intended to lose a race so his friends could have a better life, however "Unstoppable" was transferred to him when he slowed down, resulting in him killing two of his friends and injuring the other by crashing into them. He joined the Union soon afterwards.

Isshin (一心)

A large and muscular woman in a large suit of armor. Anything she uses her Negator ability "Unbreakable" on is granted enhanced durability, to the point of becoming indestructible. Her real name is Haruka Yamaoka (山岡 春歌), "Isshin" being the name her family carries as blacksmiths, and is bestowed upon who next gains the ability. She is the 13th to bear the name, which causes her anxiety and fear of not living up to her title. A running gag is that she is too anxious to talk and communicates through signs. Her grandfather takes her place during the final loop, as she is still a baby when Fuuko recruits them.

Phil (フィル, Firu)

A young boy with a body made of artifacts. His ability is "Unfeel", which negates his senses and emotions, allowing him to use artifacts without suffering their side effects.

Nico Vorgeil (ニコ＝フォーゲイル, Niko Fōgeiru)

Voiced by: Kōji Yusa[3]

The Union's top inventor. His Negator ability "Unforgettable" renders him incapable of forgetting any and all information, starting with the death of his wife, when his ability manifested, no matter how minuscule. Thus, his mind is being "crushed by a never-ending stack of information." He fights using levitating, orb-shaped devices called Psycho Pods which he stores his unnecessary memories on and information on fighting styles so he can replicate them. They can also be used as lasers, transportation, and create clones of people based on Nico's memories called "Astral Dolls".

Chikara Shigeno (重野 力, Shigeno Chikara)

A recently awakened Negator. He is somewhat cowardly and tends to panic, but will show courage when he needs to. His ability is "Unmove," which negates the movement of anything he looks at so long as he himself is not moving. Like Fuuko, he accidentally killed his parents when his ability first manifested.

Gina Chamber (ジーナチェンバー, Jīna Chenbā)

Voiced by: Aoi Yūki[3]

A former member of the Union. She was an elderly woman from Russia who used her ability "Unchange" to allow her to negate any change in inanimate objects, which she used to make herself look younger by using her negator ability to freeze her makeup in place. She fell in love with Andy, but was killed by him so Fuuko could join the Union and died peacefully after Andy kissed her and said she was beautiful, even after her true age was revealed. Her ability manifested when the UMA Heat attacked her village, resulting in her ability freezing the air and killing 40,000 people by suffocation.

Void Volks (ボイド＝ボルクス, Boido Borukusu)

Voiced by: Kenji Nomura[4]

A heavyweight boxing champion and former member of the Union. He has no qualms with murder, and believes that Negators who are not part of the Union are "UMA Freaks". His Negator ability, "Unavoidable" negates his opponent's ability to dodge when he assumes a certain stance before attacking. In the original loop, Andy killed him with his Parts Bullet when Void failed to circumvent his regeneration. He is recruited by Fuuko during the final loop, his tragedy of killing his final opponent in previous loops having been averted by her and his love of boxing invigorated.

Ichico Nemuri (イチコ＝ネムリ)

Nico's late wife and Mico's mother. She served the Union as both a member of the Roundtable and a member of the science division, where she met Nico. Her Negator ability, "Unsleep," rendered her unable to sleep, which eventually led to her death via exhaustion. In the final loop, she avoids her fate by learning astral projection.

Billy Alfred (ビリー, Birī)

Voiced by: Rikiya Koyama[3]

Originally a member of the Union, but later revealed to be a traitor. His Negator ability was thought to be "Unbelievable," which let him shoot bullets in directions that seemingly would miss his target, but would ricochet in order to hit them. His true Negator ability, "Unfair," negates the fairness of a user having only one ability, granting him the power to copy other abilities as long as the target views him as an enemy. As a result, he has access to several Negator abilities. This is later revealed to be a ruse, as Billy used his betrayal to gain the abilities of the others so they would not have to die fighting God. He is blind but has enhanced hearing as a result. In the 101st loop, the interpretation of his ability changed, and Unfair activates when he acknowledges another's strength.

Rip Tristan (リップ＝トリスタン, Rippu Torisutan)

A killer and a member of Under. His Negator ability, "Unrepair", negates the ability to heal any wounds he inflicts on people. He also has the "Blade Runner" artifact, which creates blades when he kicks and allows him to fly.

He was formerly a surgeon whose ability led to the death of his lover Leila. He and Latla seek the Ark in order to return to the past and save her, putting them at odds with the Union.

Latla Mirah (ラトラ＝ミラー, Ratora Mirā)

Rip's closest friend and a fortune teller. Her Negator ability, "Untrust", negates her predictions, allowing her to redirect attacks that she believes will hit her, and make the opposite of whatever she believes will happen occur instead.

Feng Kowloon (ファン＝クーロン, Fan Kūron)

A Chinese martial artist who always wears a hood, later revealed to be Shen's old mentor. Obsessed with being the "strongest in all of creation", Feng took on disciples to raise, including Shen and his sister, but intended kill them so he may get stronger. Feng is responsible for the death of Shen's sister, the catalyst for Shen's quest for strength. Though an old man when he meets Shen, he restores his youth with the artifact "Life is Strange", which he also uses to resurrect Rip. His ability, "Unfade", prevents him from aging or dying from old age.

Creed Deckard (クリード＝, Kurīdo)

Burn (バーン, Bān)

Akira Kuno (久能 明, Kunō Akira)

A manga artist who wrote To You, From Me, Fuuko's favorite manga series. Akira is a Negator with the ability "Unknown", which caused his entire existence to be unnoticed. He has a G-Pen artifact that allowed him to bring his drawings to life. He used the artifact to create an alternate persona, known as "Anno Un", in order to bypass the effects of his ability. The artifact also granted him knowledge of the future, allowing him to see events that would occur surrounding the Union and Under and allowing him to leave hints in his manga series. During the battle with UMA Autumn the G-Pen was destroyed, rendering Akira imperceivable once again, though he is satisfied that he saved Fuuko's life and that his newfound friends will never forget him. Fuuko stops him from picking up the G-Pen in the final loop, allowing him to live a normal life.
