Her slender build might be described in detail when she's running through the school corridors to gather clues. Her gentle personality could lead to her befriending Shinichi in a very sweet way, like sharing her thoughts on the case over a cup of tea in the school garden.

Aria's slender fingers turn the pages of the book delicately as she explains her theories to Shinichi. Her gentle voice is like a soft melody.

I recommend Witch Chasing Her Husband: The Genius Witch Doctor. Although the female protagonist of this novel was a demoness, she was very gentle, smart, and had very high witch doctor skills. This was a fantasy romance novel about a different continent. The plot was very interesting. I hope you like my recommendation.
