Why are you such a pervert, Araragi-san?Oh, speaking of which, Araragi-san...What?! How could you grab a sound-minded model student such as myself just to speak so horribly of him?What is it, Hachikuji? You're being unusually formal.Are you sure you don't mean soundly criminal model student of perversion?The original Japanese puns are approximately as follows: kenzen is both "sound-minded" and "about to be imprisoned"; mohan is both "model" and "criminal pattern"; seito is both "student" and "sex-crazed".I know this is a comic, but I think if we're having conversations where the best parts can't be understood without looking at the characters, something is seriously wrong!
