Reito-sama said: Chihina: Kamen Rider W (Chihina-san)!!
It says "(Gotou-san)" not "(Chihina-san)". It's a seiyuu joke, since Gotou Yuuko voices Mikuru and Bell Zephyr, and Gotou Saori voices Chitose and Barasuishou.
This tickle a bit, aru!Ch, Chitose-san...!Right!TRANSFORM!!KAMEN RIDER W (Gotou-san)!!Eh?
