Episode 1: The Princes Who Fell From the Sky
Arise Satō (佐藤 有世, Satō Arise)
Yôka (Yōka) is one of Nina Yamada’s two best friends.
Yôka has black hair which she wears in buns and periwinkle eyes and she always has a fringe in her hair.
Yôka is a rather serious character in comparison to her friends. She appears to be concerned about her academics and passionate about school.
However, she is ultimately incorrect, seeing as Zero and Ichî come into the picture. She and Yôka begin spending less time outside of school with Nina during the Exam, having no choice since Zero and Ichî are stuck to her like glue. She and Yôka constantly ask Nina about her relationship with Zero and Ichî.
Yôka later plays a significant role as one of the directors of the school play, casting the characters and begging Forte to play Snow White.
After the Exam, Hatsuka and Yôka start hanging out with Nina again, supporting her and comforting her when Zero doesn’t come back, but she ends up being pushed away when the second Exam starts, though she still remains close friends with Nina.
