In the Anime
She is usually elegant and graceful when teaching her class, but she isn't serious and can be mischievous when she isn't teaching. She knows about Comb-bowie Sensei's crush on Musicatchi Sensei, and likes to cause him problems whenever he tries to confess his feelings to her. When Comb-bowie Sensei is upset, Ms. Modetchi often watches and grins to herself.
She is also seen flirting with Comb-bowie Sensei, but it is unknown whether she does it because she truly has affection for him (also explaining why she prevents him from confessing to Musicatchi Sensei) or if she just does it to distress him more.
She is voiced by Akemi Okamura.
Her name comes from the Japanese word "moderu" (モデル), which means "model".
