Utage has the appearance of a very young girl, although she is actually the Kanade's homeroom teacher. She has long, bright pink hair, an ahoge, and green eyes. A small section of her hair is tied into a ponytail by a blue bow on the left side of her head. She tends to wear casual clothing, such as a long-sleeved t-shirt under a short sleeved shirt and a semi-short skirt. Kanade describes her as a "legal loli". She is sometimes seen with a small lollipop in her mouth.
Utage has a rough, rather crude personality, and speaks in a casual tone. She is apparently a former pro-wrestler, and once even used a choke hold on Kanade during homeroom. She claims that "Absolute Choice" messed up her personality, and that she used to be more polite and reserved, however Kanade says there's no way that's true.
In the past, Utage has experienced the Absolute Choice. She was somehow able to complete all of the absurd missions given by God and eventually get rid of the curse.
Because of this, she seems to have a lot of knowledge about the curse. Unfortunately for her though, even if the curse have been lifted, there were still some shackles left. Whenever she tries to share the information on how to end the curse, she will get painful headaches.
