Tsumugi is an honors type student who speaks in a docile and gentle way, but she becomes very passionate when she talks about her favorite series or cosplays.

While Tsumugi is the Ultimate Cosplayer, she only enjoys making costumes, not wearing them, as she is not really fond of people looking at her.  However, she hates cosplayers who care more about standing out than love of the characters, so she wears her own costumes as well but with love.  She deeply loves cosplaying as she states that cosplaying is an expression of love. She has deep respect for fictional characters and gets very offended if they are disrespected.

In this reading, Tsumugi should speak with confidence and enthusiasm.  She's speaking as a Danganronpa fan, and addressing other Danganronpa fans.  Think of her as a passionate fan talking about her favorite show, and trying to get others interested in it too.
