Ariel

Haruna's teacher at her magical school, also known as Dai-sensei (大先生 lit. Great Teacher), who has an affinity for Kyoto-style tofu and sends Haruna to get her some due to her credit cards being overcharged. It is unknown what her true motives are. ~! 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 top pupil, Chris, as the leader of the coup. It ultimately failed, and Chris and a few others involved took the fall; however, Ariel herself apparently managed to escape punishment. !~
