宮下 かなた

The circumstances on the accident that lead to the death of her parents have resulted in a strange disorder that has stopped her mental and physical growth.

Her speech and mannerisms are very juvenile, and it highlights the large gap between her actual age and behaviour. She always carries a stuffed orca around.

She sometimes sees hallucinations of her mother and father from her memories before the accident. She has recently started seeing her father in the protagonist, and has begun calling him "papa" and adores him greatly.

She is a shy girl who always acts as if she is hiding behind Kurumi, because her sister is her only living relative.
