Animenewsnetwork - Masako Shimomura has a secret. It's not a surprise to anyone who's been watching Magimoji Rurumo thus far, but it's a secret she'll do almost anything to keep from getting out. The bespectacled girl, a quiet background member of the Disciplinary Committee, is...a cosplayer! Cue the gasps—well, there are none. Pretty much the only times she's been worthy of attention before is when she's admiring Rurumo's witch "cosplay" or whisking a cosplay accessory out of sight.
