Ariel is a supporting protagonist in the light novel and anime series Is This a Zombie?. She is Haruna's teacher at Matellis, who has an affinity for Kyoto-made tofu and sends Haruna to get her some due to her credit cards being overcharged. She is also known as the Head Teacher.

She is voiced by Ai Shimizu in the Japanese version of the anime and Monica Rial in the English version.


She has whitish-light blue hair with golden eyes. Her outfit seems to be a professor's uniform, mainly because of her occupation as a teacher.  Despite her youthful appearance she's easily over a century old, as evidenced by her more mature demeanor when compared to her student Haruna.]


She always smiles or is in a good mood, even when dangerous events occur. Though sometimes she takes risks. It is unknown what her true motives are. She is very protective of her students and will kill anyone who harms them.

It is later revealed that she had planned to overthrow Lilia Lilith, the Queen of Villiers, a century before the events of the series, and appointed her mentor, Chris, as the leader of the coup. It ultimately failed, and Chris and a few others involved took the fall, with Chris herself cursed into the form of a middle-aged man; however, Ariel herself apparently managed to escape.  She "reformed" for appearances' sake, but still strives to stop Villiers' constant warring with other kingdoms, especially the Underworld.
