She has a tomboyish side but usually handles housework. She is suspicious and hostile toward the Blue Dragon tribe due to their rivalry.

While she calls Azusa her sister and claims her feelings are sisterly, she often hints at romantic interest. In Season 2, Episode 8, she refers to an invitation to an art exhibition as a date.

Laika is a Red Dragon who first appears challenging Azusa to a test of strength, claiming to be the strongest in the province of Nanterre. After being defeated, she decides to become Azusa’s student to improve herself.
