I was watching the Making of Boukenger VS Super Sentai and I was wildly amused by Hiroya Matsumoto (MagiYellow)'s interview. At some point, Hiroya does the MagiYellow henshin pose and he covers his armpit with his free hand (the interview was filmed during Tsubasa's boxing match).
The interview with Yosuke Ichikawa was rather short, though. :(
I like how the staff tries to keep Haruka's (BoukenPink) hairstyle neatly. XD
