When 九十九十九 (Tsukumo Juku) came out in bunko, the covers happily described it as meta squared.
Tsukumo Juku himself is a character from Seiryoin Ryusui's meta/deconstructionist mystery novels (which are fascinating in theory but rather boring to actually read, sadly) and Maijo Otaro took the character and sprawled him into a horrifically long series of contradicting slices of his life, at one point declaring him so beautiful all who saw him fell in love, while also informing us that he has two heads and is disgusting. The character is regularly killed off throughout the stories, and at one point escapes into the real world and murders the editor working on the novel.
Maijo has been quiet for a few years; his last big project, The Disco Detective, has yet to come out in bunko (along with his second novel) but everything else kinda has. He did a thing on his website where he pitched a movie idea every week for a year, and each was more bizarre than the last. He seemed to be making a serious effort to move into film.
Apparently, he has. There's a movie out this summer called Neck (trailers appear to not be online yet), and he has a story credit. Plot appears to be standard boy meets girl, girl turns out to have a terrifying disembodied head in a tank in her laboratory. Never one to be satisfied with simplicity, he has also written a stage play on a similar theme.
Both productions feature a character who is a popular novelist name Echizen Mataro.
Echizen Mataro is launching a new series of books from BOTH Dengeki Bunko AND Kodansha Novels this April. One Pluto 0 novel from each in April, two each in June, and there's already one more scheduled for after that.
Echizen Mataro is giving interviews vehemently denying that he is from Fukui (Maijo Otaro is -- the fact that Maijo notoriously refuses to make public appearances is a small part of this whole stunt), declaring that Jojo's Bizarre Adventure is the greatest manga ever, that he is also an actor appearing in the movie Neck, and that he has the mysterious supernatural ability to divide himself into two people and write two novels simultaneously in his sleep.
Words fail me.
Edit: Apparently this awful thing is the Dengeki Bunko cover. I remember seeing that and thinking it was unspeakable. I trust Maijo enough to think he could make the wheelchair girl not the pandering moe cliche I assumed it was, but anyone wearing one pant leg pulled up like that is begging to have it chopped off.
Edit 2: Movie website. How could it not have Kuriyama Chiaki in it? Joe said much the same thing about Nicolas Cage when I sent around the trailer for Kick Ass, so I guess I've just proven that Kuriyama Chiaki is the Nicolas Cage of Japan.
