I'm dying to see it, so any help would be awesome :)
Also I was wondering about some issues.
1) Who in Kanjani8 smokes?
From what I know Yoko said in one episode of Recomen that he quit and he accused Hina of smelling bad, so Hina probably still smokes. In one of older entries from Subaru's j-web he said that he quit something bad for his health and I assume he might have been referring to smoking. Ohkura said during one of his solo cons that he's trying to quit, but I don't know whether he succeed. I heard that Maru doesn't smoke but I don't know if that's true and I don't know anything about the rest.
2) I've thought about compiling a list with how the boys usually call each other ^^ (I don't mean how they sometimes refer to each other with -san on TV, e.g. location shoots)
Yokoyama Yuu - Yoko (Subaru, Hina), Yokocho (Subaru, Hina, Yasu, Ohkura called him that once), Kimi-kun (Yasu), Yuuchin (Maru), Yokoyama-kun (Ryo, Ohkura)
Shibutani Subaru - Subaru (Yoko, Hina), Shibuyan (Yasu, Hina, Maru), Subaru-kun (Maru?, Ryo, Ohkura)
Murakami Shingo - Hina (all except Maru?), Shin-chan (Maru), Murakami-kun (Yasu, Ohkura)
Maruyama Ryuhei - Maru (all), Maru-chan (Yoko), Ryu-chan (Subaru)
Yasuda Shota - Yasu (all?), Yassan (Ohkura), Sho-chan (Maru), Yasuda (Yoko sometimes), Shota-san (Subaru)
Nishkido Ryo - Ryo (all except Yoko?), Ryo-chan (Ohkura), Dokkun (Yoko), Nishikido (Yoko), Ryo-kun (Subaru)
Ohkura Tadayoshi - Tatsuyoshi (Maru, Hina), Tatsu (Hina), Tacchon (all except Yoko), Ohkura (Yoko, Subaru), Kuranberi/Cranberry/or something like that (Yasu)
That's what I know, any alterations/other nicknames?
