Aya Arima

As the youngest of three siblings and the daughter of Kojirou, this character possesses a deeply compassionate and sweet nature. Despite her kindness and genuine care for those around her, she frequently finds herself on the receiving end of her father's intense temper. Because Kojirou perceives her as being particularly clumsy and irrational, her childhood is marked by a difficult struggle to avoid his frequent outbursts of wrath.
