Riko Yamikawa Jirai-kei (explodes if touched). Doesn't realize Hikari Tada is Hikaru Tada. Thinks she's amazing because she's so "sparkly"(?). Look up the rest for yourself.

Mirai Misato Vision. Can see the future. Gyaru. Doesn't realize Hikari Tada is Hikaru Tada. Gave Hikari Tada the nickname "Pikarin." Look up the rest for yourself.

Shoko Taira Parallel world traveler (Butterfly Effector). Doesn't realize Hikari Tada is Hikaru Tada. Gyaru. Always with Mirai. Calls Hikari Tada "Pikarin." Look up the rest for yourself.
