After meeting our hero, will she find a new direction in that regard...?

A mysterious girl who suddenly appears at Komatsu Detective Agency and declares herself Deputy Director. She claims that she met the actual Director, who is currently away on business, in a foreign country, and he entrusted her the role of Deputy Director in his stead.

She’s free-spirited and marches to the beat of her own drum, becoming a bit of a nuisance for Satomi and our hero. However, the detective skills she learned from the Director are second to none.

She gradually works her way into our hero’s daily life, but all the while she has a dark secret of her own...!
