I had watched it on some Asian channel a long time ago, but I can’t find any information about it anywhere anymore. I remember a few of the characters being named something along the lines of “Fandom” and “Mandom”. I also recall a scene where one character claims he can block any attack, and encourages his friend to attempt to stab him with a real knife (and fails to block it, with more attempts to follow). I understand it may be extremely vague, but any assistance will be welcome. Thanks!
