Characters
Keyaru (ケヤル) / Keyarga (ケヤルガ, Keyaruga) / Keara (ケアーラ, Keāra)
Voiced by: Yuya Hozumi (Keyaru/Keyarga), Yoko Hikasa (Keara)
The Healing Hero and the series' main protagonist, who was blessed with the hero's insignia from the coming-of-age. He, however, wanted to save the world from demons only to endure four years of physical, mental, and sexual abuse at the hands of his own allies, making him see how corrupted the Jioral Kingdom is. In the midst of the battle with the demon lord, Eve, Keyaru managed to retain himself finding the true nature of his power and obtains the Philosopher's Stone. Instead of handing it to Flare as instructed, he uses the item to travel back in time, all while being able to maintain his memories of the original timeline, to exact revenge against his torturers and bring down Jioral. During this, he changes his appearance and renames himself Keyarga. His thirst for revenge and mostly psychopathic personality (caused by the torture he endured) makes him a villain protagonist, although he does have a caring side.
Flare Arlgrande Jioral (フレア・アールグランデ・ジオラル, Furea Ārugurande Jioraru) / Freia (フレイア, Fureia)
Voiced by: Ayano Shibuya
The Magic Hero and the first princess of the Jioral Kingdom. Flare is the main source of Keyaru's suffering and merely sees him as a baggage carrier and drugs him so he would be receptive to her commands and trains him so that he can be of some use to her. Generally, she saw healing magicians as the lowest class in the magic world until Keyaru has proven otherwise and does not trust her with the Philosopher's Stone. In the alternate timeline, when Flare is left vulnerable, Keyaru tortures and rapes her, takes her powers, erases and alters her memories and appearance to become his companion and lover named Freia, all while deceiving everyone into thinking that Flare is dead. As Freia, she is meek, kind, and obeys Keyarga's every command, including sometimes "acting" as Flare, caring only for him above all else. She is one of Keyarga's closest allies.
Setsuna (セツナ) / Nayuta (ナユタ)
Voiced by: Shizuka Ishigami
A female demi-human slave that Keyaru buys and recruits into his party. Prior to this, she was infected with an illness (which Keyarga helps to cure), but her rage allows her to withstand it. Setsuna comes from the Ice Wolf clan whereas estranged from humanity and usually sold into slavery that defeats the purpose of equality in the Jioral Kingdom. As Keyarga offers her the chance to avenge her tribe, she reveals her unspoken true name to receive empowering strength from Keyarga, allowing him to gain control over her. Setsuna later becomes sexually attached to Keyarga and often competes with Freia for his affections. Similar to Freia, she is also Keyarga's closest companion.
Eve Reese (イヴ・リース, Ibu Rīsu)
Voiced by: Natsumi Takamori
A female black-winged demon who is one of the candidates to become the Demon Lord. In the previous timeline where she did become the Demon Lord and fought Keyaru in the bitter end, she tearfully begged him to spare her and granted him the Philosopher's Stone, prompting Keyaru to know what she was really trying to protect. Her objective is to kill the current Demon Lord for trying to exterminate her brethren. When she completes the trials of Caladrius, her hair changes from black to silver. In the alternate timeline, she becomes a member of Keyarga's group. After forming cooperation with her newfound empire, Eve and Keyarga develop mutual love for each other and unlike the other girls, they have proper sex.

Voiced by: Minami Tsuda
The second princess of Jioral Kingdom, and younger sister of Flare. Both sisters had a close relationship until Flare received a higher reputation for awakening as the Magic Hero and belittles Norn. Compared to her big sister, Norn is a strategist who runs her kingdom in a sadistic and manipulative manner and aims to drive Flare out of the throne. In the previous world, Norn saw through Keyaru's scheme and revenge plot but foolishly lets it slide, making him see Norn his greatest foe. Following Flare's apparent murder, Norn meant to gain aid from neighboring kingdoms by exterminating all innocent demons, after her soldiers killed a friend that Keyarga got to know. He and Freia halt her schemes and capture her. As he did with Flare, Keyarga rapes her and erases and alters Norn's memories and appearance to become his little sister named Ellen. As Ellen, she has a brother complex and views Freia as a "big sister".
Kureha Clyret (クレハ・クライレット, Kureha Kurairetto)
Voiced by: Natsuki Aikawa
A female knight of Jioral Kingdom, renowned as the Blade Goddess. Kureha owes Keyaru her gratitude for fixing her amputated arm from their first meeting. She initially opposes Keyaru's party after believing that they were attacking soldiers who were trying to protect Setsuna's village (not realizing that the soldiers were actually threatening the villagers), but allies with them after learning of her kingdom's atrocities. Freia pretends to be her old self to yield Kureha to her words. After being exposed to aphrodisiac and becoming an obedient ally, Keyaru rapes Kureha as punishment for going against him; Kureha does not resist as she has truly developed feelings for him, and also has her act as an informant for him. Her constant flirting with Keyaru makes the other girls jealous. She eventually becomes the successor of the Sword Hero.
Bullet (ブレット, Buretto)

He worries that he will have to sacrifice Eve to confront Bullet.
Blade (ブレイド, Bureido)
Voiced by: Mami Fujita
The Sword Hero, affiliated with the Jioral Kingdom. She has an intense homosexual infatuation that urges her to rape ideal girls to death. In the previous timeline, Blade would torment and physically beat up Keyaru every night for "touching" Flare to beset her frustration. Although she is one of Keyaru's torturers, Keyarga does not erase and alter her memories and appearance like how he did to Flare and Norn, instead leaving her to be eaten alive by brainwashed men. Blade is the only person to know of Keyaru's past life.
Anna (アンナ)
Voiced by: Asuka Nishi
A villager from the same village as Keyaru. Anna provides Keyaru food and shelter since his parents' deaths. She encourages Keyaru to follow his belief in changing the world for the better.

When Proum learns of this (although both he and Leonard are unaware that Flare is still alive), he is released and sent to hunt down Keyaru, who by now has changed his name to Keyarga.
