UPD3 WHO IN THE JIMUSHO IS HUMAN AND WHO'S NOT and my theory is as follows
Daisempai - Higashiyama is the original version 1.0 jimusho robot
SMAP - all human, but Goro did sell his soul to the devil once. Mostly for fun, but partly for something to do with his hair. The devil realised pretty soon that he was in wayyyy over his head with SMAP, and likes to pretend the whole thing never happened. читать дальше TOKIO - All human. Even Leader.
V6 - Many people (though most often Taichi) have tried to figure out what the hell Okada is, but so far no one but he himself knows (except probably Domoto Tsuyoshi, but he's pretty good at not telling as well)
KinKi - the only 100% non-human group: one (1) jimusho robot, version 2.0, and one (1) space alien.
Arashi - Like Goro, all of them (except for some reason no one's quite sure of MatsuJun) sold their souls to the devil. Unlike with Goro, the devil's never regretted this deal.
T&T - Tsubasa is secretly a superhero by night. His superpower is invisibility.
News - Yamapi is a zombie. He died sometime just after News debuted, and the jimusho brought him back with black magic. They have a team of 7 people constantly working on keeping up the spell that keeps him walking and talking.
