Yukiho Kosaka

Kousaka Yukiho is the younger sister of Kousaka Honoka and a minor character in Love Live! School Idol Project.

Background
Yukiho's family own a Japanese sweets shop. She lives at the back of the shop with her mother, father, and big sister.

Personality
Yukiho is often shown doing embarrasing things when she's by herself. Despite constantly scolding her sister, Yukiho really does care about her older sister. An example would be in episode 11 when Yukiho dropped her umbrella and ran over to Honoka, crying out her name, after she fainted.

Relationship
She is the only little sister to Kousaka Honoka. It is also hinted in the anime that she has a good friendship relation with Ayase Arisa, Ayase Eri's little sisters.

Chronology
In Episode 1, it is shown that Yukiho doesn't plan on applying to Otonokizaka High School but to UTX, a very popular high school that is getting tons of students because of its idol group A-Rise. Yukiho says that there's no point in going to Otonokizaka since it's closing.

Yukiho doesn't make another appearence until episode 11, when she went to go see  μ's performance at the School Festival along with Ayase Arisa. Earlier in the episode, however, Yuhiko was surprised to see Honoka exercising at night. After Honoka goes, the camera zooms in at a Otonokizaka High School admission that Yukiho was most likely going to fill out. Midway through the episode, Yukiho was clearly concerned that Honoka was overworking herself by going out to jog in the rain. Honoka's response that she was only going to run for a little bit. It wasn't until after μ's performance that Honoka suffered the consequences of not getting enough rest, and fainted. Worried, Yukiho drops her umbrella and run over to her older sister, crying out her name.
