Akane Akaza

Driven by an intense, secret obsession with her younger sister, Akari, this character harbors a fixation that remains entirely hidden from her sibling. She maintains a massive collection of Akari-related memorabilia, a hoard so extensive that it leaves Kyouko utterly stunned upon discovering the contents of her bedroom. Though she appears to be a typical older sister, her hidden passion for collecting traces of Akari defines her true, unsettling nature.
