Yagami Tsubasa

A second-year student.

Unlike her calm older sister, she has a lively personality.
If anything, she is the type to think after she acts.

Although she is not so good at studying, she has excellent athletic ability and is also skillful. She has good instincts and can quickly become average at most sports.

It's not that she can't study, but if she works hard, her grades improve.
On the other hand, if she doesn't work hard, she won't improve, so her grades fluctuate greatly depending on her mood at the time.

She has an extraordinary ability to concentrate, but once she does, she sometimes loses sight of what's going on around her.

When her older sister Sawa goes missing, she tries all sorts of things to find her, but there's no progress, so as a last resort, she decides to disguise herself as a boy and transfer to the boys' school where Sawa worked.
At her new school, she calls herself "Yagawa Tsubasa."

She has a lot of trust in her childhood friend, Satoshi, and when she has any problems, she is the first person she consults.

Her parents died in an accident several years ago, and her only relative is her older sister Sawa.
Her parents left her a large inheritance, so she never had to worry about anything financially.
