A first class adventurer and an executive of the Loki Familia. Among the small fraction of first class adventurers, she is considered one of the strongest.
Ais is a mostly quiet person who has trouble expressing her feelings through words so because of this she is thought to be mysterious yet she is actually mentally young. Ais doesn't look down on the weak despite being a First Class Adventurer but she is also believed to be an airhead, namely due to her quiet nature, however is very strong-willed, doing everything to reach her goal to become even stronger, even offering to train Bell just so she could try to determine the key to his quick growth. She also tends to react violently whenever someone does anything remotely perverted to her.
(Will fill out more later just trying to keep it simple mostly.)
