Sister of Ageha Yoshina. Like her younger brother, she has a rough, aggressive personality and frequently uses the phrase "I'll kill you."
Surprisingly, she is also very tidy, and it is said that a few times a year, she becomes uncharacteristically affectionate toward her brother.
With their parents absent, she acts as a guardian to Ageha—though he finds her presence rather bothersome. She is strict about curfews; whenever Ageha returns home late—often due to getting into fights—he ends up being punished by his sister.
She was once in a relationship, but was dumped by her boyfriend. Currently, she is a fan of the idol-actor Oboro Mochizuki and remains single.
