I actually have a physical copy of Kyo's first book, just need the second one with "mama".
Regarding the TMNS demo tape, yes, that's what I'm looking for. I've never seen it ripped anywhere, some dude on batsu had it back in the day but I can't register an account there.
It's one of the most rarest releases, along with the message tapes, DEG live in Hongkong, the GAUZE promo LP and some other stuff.
Oh and Sea of Retards is a hoax, I know that much.
And I still don't know who the person on that picture is. Is it Kisaki or who?
