teach-kun has a bad memory most of the time but can remeber important details from time to time, he is aware of sam-kun's existance and tries not to forget it, but fails most of the time, he tries to be helpful despite his bad memory and having to deal with a yandere(sam-kun), an alcoholic(kobayashi) and some alien-rabbit thingy(dada-sama). Likes kobayashi, unknowing of sam-kun, DESPISES dada-sama
