Aya Arima

Kojirou's daughter and the youngest of the three siblings. Although she was a very sweet child who cared a lot about others, she was often the target of her father's wrath, as he considered her to be the most clumsy and irrational.

~!After her father forced her to go back to school late at night to pick up a notebook that she forgot to take home, she would fall victim to a serial killer, prompting the family to break apart and traumatize her oldest brother.!~
