Tanaka YuaSecond Heroine
The MC's little sis, who is spoiled and really pushy in what she wants, hugs the MC a lot too.
She has a tendency to look like she wants to remove any other woman she sees.
She is a bit aware of Inoue's existence, or the person that loves her brother. Not sure what to do but to observe for now. Doesn't like it when there's something in the MC's room that she doesn't know.
Dedicated bro-con.
