when you finished the final selection, You finally got your uniform. But it had an open chest. When you wore it you felt really uncomfortable.

"Little sis? Are you okay? You've been staying at the bathroom for so long now, come on out."

When you came out of the bathroom wearing the uniform, Obanai went REALLY furious.

"What the hell..? Now who has the guts to give THAT kind of uniform..?!"

Obanai has been overprotective of you ever since he let you became his adoptive sis.
