Kou Hayama

Kou Hayama is the older sister of Teru Hayama, and the two could not be more different in character. She carries a perpetual gentle smile and radiates an almost otherworldly, ethereal aura. Despite her genuinely kind heart, her thought process operates on a completely different wavelength from everyone around her—leading her to casually drop shockingly harsh remarks or unintentionally spark chaos without a hint of malice. This makes her widely regarded as the most dangerous individual in the series. She has a deep passion for health foods, though her culinary experiments tend to produce mysterious dishes that leave those who eat them in a rather alarming condition.
