Matsuyama was Toriyama's close friend and he was one of the guests of Manga Barcelona (Friday 5th to Monday 8th of November -> https://www.manga-barcelona.com/es/inicio.cfm).
Being a dirty mexican adoptee I do Speak Spanish So I Went There
I was able to interview him for the one and only ANIMELAND magazine (as I was closeby and I said I'd jump him, which I fully did lol) and attend all of his Masterclasses / Meet and Greet / live drawings and QnAs.
You can watch his QnA on the salon's VOD on twitch (available for a few days still) at around 4h27: https://www.twitch.tv/videos/2636722765
(sadly they did a solid part of it in Catalan lol, but if someone understands japanese well enough, please do a JPN transcription!!)
He said his impression of Torishima was that Torishima was someone who "scolded Toriyama a lot" (but after reading his recent book BOTSU, "he's a good person after all" he said)
He also gave his schedule when it came to working with Toriyama (arriving at his house during the evening, having dinner, having a bath after the family, then working until midnight, having a snack, then working until 4am)
Due to obvious stuff, he wasn't willing to sign anything "by Toriyama", such a DB books or merch, (or even Dr Slump), but in the case of BIOSPHERE, where he did all the colors and backgrounds, he accepted signing it (or at least he accepted signing mine, but I had extra aura so maybe I was given an exception lol).
He was also happy to see a LOT of people bring the spanish fanzine BirdlandPress2.0, where he was an interviewee for number 1, and a contributor for number 2 (and onwards). (https://birdlandpress2.com/ pdf for n°1 is free and up for grabs here, and the physical copies are Spain only, and of course it's all in Spanish...)
Soooo... yeah. Since there was so much stuff that was asked / said / commented / shared, please AMA about anything here and I'll do my best to tell you all about it
