Wow, hunting down explanations for those convention names was...eye-opening.
Anyway, the artist's Pixiv description says his group actually all drank green tea out of urinalysis cups. He enjoys jokes like that more than he expects.
I think QB is the shady guy who goes "I mean, yeah, it's about peeing and stuff, but if you don't want cash well that's ok I guess I'll just pay someone else this stack of money I mean it's not like you need money to live or anything."
I wonder how many Hitomi Dojins the tummy punch convention got?
And they're short on staff.

Schedule
C-mus, Hara-pan and Lo-ket are all at the same venue. Hara-pan apparently comes from "hara ni panchi" ("punch to the gut"), and focuses on a fetish for that minor physical abuse. "Lo-ket" is a lolita-fetish convention, if you couldn't guess.
Trash
There's also C-mus. A convention for urine-fetish material. The name comes from "shii-shii musume", "peeing girls".
