Piloting daimidaler centers around fondling breasts.
In the first episode Koichi gropes Kyouko which reveals his ability to produce HI-ERO particles and charge Daimidaler. In the second episode Koichi had gotten bored of Kyouko's boobs and only starts producing them again when he rips open her shirt and lifts up her white bra to see half of her nipples.
Each female character gets their own unique bra which for each character uses it consistently.
Chieko has more of a triangle bra than a round bra and just like Kyouko her bra is revealed by Koichi.
Kirikos bra is more pink than Kyoukos bra is and also has a bow in the middle of it.
None of these characters bras are seen in the anime except in Koichi's fantasy so it may not be canon but Moriko has a bright red and black bra with a pattern, Soriko has a pink bra and Sewashiko has a light purple bra with a bow.
The panties of all the characters match the colo(u)r(s) and design of their bras. Edit
