Fujikawa Himawari

Weakness: Being tickled. Gets sexual excited when body or hair is lightly touched.

Has excellent grades and is a member of the tennis club where she also excels. She is also a member of the student council and looks to be next in line for student council president.

She has known Tsukushi since childhood, however, she has no romantic interest in him or any man at all because she is a lesbian. Rather, she has strong feelings for his sister, Nadeshiko, which she keeps to herself.

One day however, she witnesses Tsukushi and Nadeshiko having sex and misunderstands it as Tsukishi forcing himself on Nadeshiko...

"You already know that I love Onee-sama, so there's no need for me to tell it to others."
