Naruse Kumi

Always full of energy, she is an innocent and honest schoolgirl of today. She is Makiko's daughter and Kazunori's niece.

Since she has lived in the same house as Kazunori since birth, she calls him “big brother” and loves him like an older brother. She has started to view her uncle as a man, lately.

However, since he is not noticed, she is always looking for a chance to attack him, and if anything happens to him, she will come on to him.
