Banned in China — the animated film adaptation, Midori, is banned in Japan, and the master reels were confiscated.
Draco in Leather Pants: Muchisuke the mummy man; a noticable amount of the manga's fan base loves him despite the fact he rapes Midori multiple times, even in the live action version
Kanabun as well is fairly well liked despite killing puppies as his introductory scene. In the live action version, he is surprisingly played in a creepily appealing and also sympathetic way by Su G's Takeru, who portrays him like an excited little kid.
Jerkass Woobie: Kanabun in the live action film. It is hard to root for him, given his actions, but it's hard not to feel sorry for him when Mr Arahi, his lover, sells his body to the government official in order to keep the freak show going. His bitter attitude is almost justified if he didn't try to kill Midori.
Even worse, selling his body was all for nothing when he is abandoned for a new boy toy near the end.
