I've never loathed an MC as much as I loathe Asaishit. His character was incredibly annoying and I honestly hated every chapter except chapter 5. That piece of shit got what he deserved (in my opinion) Loved onii-chan so much, the best badass big bro ever. And loved Yoru although I wish he didn't end up with the doofus in the end. Onii-chan and Yoru were the only reasons that made this worth reading. (Sorry Harada-sensei, still love you and your other works)
