あとがき / p o s t s c r i p t
Seiko has an overactive imagination, so it seems. Making a reference to a certain spats-loving mecha-girl anime but with some mild artistic liberties.
ソワ [sowa] : Used as a sound effect for fidgeting
ビ( )ッド( )ペレーション [bi?ddo?pereeshon] : A reference, but in a fashion such that it's not a direct mention.
