Characteristics: An average high schooler in terms of ability, his only weapon is 'Return by Death,' which allows him to return to a specific point in time upon dying, though he cannot tell others about it. His sharp, sanpaku eyes are his defining physical feature. Behavior: Initially draws criticism for his bluster and lack of tact, but eventually leads his allies using information gained through loops, sacrificing himself to achieve the best possible outcome. Emotions: His mental state often collapses due to the trauma of Return by Death, but he rises again through strong affection and tenacity. While he has low self-esteem, he is recklessly devoted to others.

Personality and Emotions: Possesses immense pride and a cynical tongue. She calls Subaru 'Barusu' and showers him with insults, but she is a tsundere with deep affection beneath the surface. Characteristics: Once a prodigy of the Oni clan, she lost her horn and now lacks mana. Consequently, her physical abilities are low and she is less skilled at housework than Rem, but her insight and judgment are top-tier. Behavior: Usually acts so bold about being lazy that it seems like negligence, but in battle, she overwhelms opponents with explosive wind magic for short bursts, though she cannot sustain it. She also serves as a pillar of support, snapping Subaru out of it with sharp advice when he falters mentally.

Characteristics: A former merchant who speaks in a Kansai dialect. Despite her cute appearance, she is a cold pragmatist who will use others as pawns for her own profit. However, this is rooted in her experience of rising from the very bottom. Behavior: Focuses on information gathering and situational analysis. She shows a bold, gambling spirit by personally participating in dangerous underground searches and cooperates closely with Subaru's group for her own intellectual curiosity and gain. Emotions: Maintains a relaxed smile outwardly, but harbors a deep inner longing to prove her own worth. She experiences complex psychological shifts due to secrets regarding her body (her relationship with the artificial spirit Echidna), revealing human insecurities hidden behind her usual calculating persona.
