Arisa Takamizawa

Height: 150 cm (4'9")

Arisa is one of the first year students in Sakuragaoka High School, a friend of Kotaro Enomoto, and the primary love interest of Ken Shibasaki.

In middle school, Arisa was shown to be somewhat submissive until the bullying incident, going along with what the rest of the class says or does even if she was uncomfortable with it. It was a big weak point for her, given how compassionate she is otherwise, but she is one to own up to her feelings if given a proper push.
She's a very courageous and outgoing girl following the incident, however. She's willing to stick up for her friends, offers them her protection, and also tries to talk with them more. She still has problems with communicating though, given that she feels insecure about the incident and she hates the feeling of being alone.
