So I was writing a reply to a comment and mentioned my headcanon that ethics, which is listed as Gakushu’s least favorite subject, is an actual course that Gakushu is failing miserably. Then I thought, “You know, I bet Karma’s in that class too and doing splendidly, since he probably does a good job of disguising his near-sociopathy,” which would drive Gakushu nuts. Thus, this cracky fic was born.
I took some liberties to make it possible for Karma and Gakushu to share a class, since I don’t think Kunigigaoka allows Class A and E to do that, and I’m not sure how electives work in Japan, so please pretend canon/reality work as described. It contains a reference to this half-written fic of mine, but having read it is not required. It just makes one line a little funnier.
