Tsumugi is docile & gentle, becomes very passionate when she talks about her favorite series or cosplays, has a habit of slipping infamous quotes. (also tends to ignore people while she's in her thoughts.) While shes the Ultimate Cosplayer, she only enjoys making costumes, not wearing them. She hates cosplayers who care more about standing out than the love of the characters, so she wears her costumes but with love. Stereotypical fan of anime and manga.
