Background / History

Komachi lives with her younger brother. Because their parents are often still at work when they return home, the siblings handle many day-to-day matters themselves. As the older sister, Komachi tends to assume she should solve problems alone, even when she is struggling. Her brother once tried to share his embarrassing chuunibyou stories because he believed she would then share what troubled her; Komachi initially responded harshly, then learned he had been worrying about her as well. 114

She knows her brother's elaborate chuunibyou setting by heart, including his story of seven gods and his identity as the reincarnation of the “Eternally Indebted God.” She memorized it so she could indulge his fantasy rather than immediately destroy it, preferring his present embarrassment to the disappointment of having it crushed. 14

Her concern for her brother becomes a recurring reason for her involvement with the Service Club. She seeks help when he appears to be suffering from unrequited love, later accepts the painful truth behind his attempt to protect a female class representative from unsafe online photographs, and resolves to speak seriously with him. 72 74

Personality
