sora's a shinya tier oyaji vk whore there isn't anyone he wont drink with LOL
i don't know about tutoring/students, but [just from what i've heard/read online idk what their relationship is] at some point when dezert stopped flopping (outo no susume era) i think he reached out to tetsu and more or less became friends with the derlanger guys
tbh something is happening with dezert's promotion, y'all remember the tatsurou x chiaki interview? either they had major connections from their dominor days and some legendary yakuza queens started backing them once they started getting popular or just played really smart with their networking and more or less won their fame.
someone from d'erlanger personally manages dezert don't tell anyone
can we get dezert jouren's tea??!?!
