Characters

Main characters

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.

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.

The Union

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.

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.

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.
