it's hard seeing the Juniors in the "Seishun Amigo" PV, but Yamada's in there. haha. he's also been backdancing at live performances also because YamaPi was carrying him in this one episode of Mini Music Station, LOL.
i also thought Kitty GYM was the biggest WTF when it was announced also.
but, what can i say, i love "Fever and Future"! and i didn't realize Yamada was in that unit.
maybe you thought Yamada was tall because Kame-chan's only 171 cm. LOL.
