Ayase Yuki

Very much the opposite of her name, Yuki is a very unlucky person. Her parents passed away when she was young, so she was raised by her grandparents. However, they too passed away upon her graduating high school. She loses hope after her boyfriend Shinohara Reiji- whom she perceived as her one and only instance of "good luck"- cut ties with her. Yuki was then taken in by Mochizuki Akira.

Though she was greatly weakened because of Reiji dumping her, Yuki is usually a very resilient, strong and cheerful person. It's not like she's bad-looking, but since she has no interest in fashion whatsoever, she appears plain.
