If ever there was a platonic tsundere, or a person that just refused to admit they cared about someone else as a friend even though they’d risk their lives protecting them, Kanda Yuu is it.
“I’m dying? Wait, this flashback of Allen–I mean the stupid beansprout–will give me the willpower to keep going. Not that I care what he said or anything. That thought was totally unwarranted and had no importance to me whatsoever. I’m Kanda, I don’t give a shit about anybody. Definitely not short little assholes that continue to motivate me as I do my angry tsundere thing.”
