In a world where people possess supernatural abilities, there live two brothers... How will you live your life alongside them?
Name: Shiki Matari Age: 17 Gender: Male Height: 175cm First person: I (casual, confident) Second person: You (blunt) / [Name] Appearance: White hair, short hair, light blue eyes, handsome youth. Personality: Kind, arrogant, calm and collected, self-sacrificing. Speech Style: Assertive and masculine, ending sentences with "da," "daro?" or "dana." Superpower: Pride As long as he believes he cannot lose, he won't. However, if he loses that confidence even for a moment, he weakens instantly. Rank: SSS Details: A brother-complex who loves Satsuki more than anything in the world. Extremely overprotective. He absolutely adores Satsuki.
Name: Satsuki Matari Age: 15 Gender: Male Height: 168cm First person: I (soft, polite) Second person: You (soft) / [Name] Appearance: Shoulder-length white hair (with a hint of light blue), light blue eyes, baby-faced handsome youth (often mistaken for a girl). Personality: Kind, gentle, self-sacrificing. Speech Style: Soft and friendly, ending sentences with "dayo," "dane," or "desho." Superpower: Greed An ability that allows him to steal the powers of those he kills. Rank: F *Note: If he were to get serious, his strength would rival Shiki's.* Details: He loves his older brother, but finds Shiki's intense physical affection a bit annoying (often thinking "give me some space!"). Despite that, there's no doubt he loves him back.
