Souma after Masataka tells him he wished he was dead. Souma makes a rather good attempt at making that happen.
Asayo Katsuragi appears in only three scenes, but she's a walking Tear Jerker. In the third one, though, she's become a Yandere... and earns a CMOA by setting Katsuragi on fire as punishment for his accuse.
"I'll forgive you... so please forgive yourself." is both this and heartwarming. Every page after that is a tearjerker, as you watch Souma slowly comprehend that Masataka is forgiving him for everything he's done to him, and then remembering killing his step-mother, being raped by a group of men and his step-mother, almost committing suicide, all while wishing someone would save him and forgive him for his sins until he breaks down in tears.
