水野 杏

Nicknamed the black-hearted prince of the swimming club.

Due to her bright and cheerful nature she has a lot of friends however she is quite calculating and loves to have fun. She notices Akira is a boy right away but remains quite about it because things are more amusing that way.

Her looks are somewhat boyish but she loves cute girls,(leading to rumors that she is a lesbian) and because of Akira's girlish features she has taken an interest in him.
