I may be a Ritsuko x Hajime shipper but the fact that Hajime dealt w/ Kana & her friends w/o hitting them like Ritsuko in middle school & even raised his threat from security guards to actual cops & actually got Kana to apologize for her actions to Haru was pretty badass. He was even inspired by Yusuke when threatening them.
I can't wait to see this in S2.
