Captain Little Sister (Patreon)

"She'd be of the captain's family, acting like a big sister even though she's younger than him. She's a bit frustrated to have no magical potential whatsoever, so she developed her physical strength to make up to it"

The character have blue hair, and I need to said that in the Itheriont's world it is possible, but always means an "magic infection". According to her personality, probably she tried to force her limits, beyond her capacities with the Magites, so suffered a small mutation: innatural hair color.

It is normal for wizzards to have it too (Alyn has purple eyes and Kazan has red eyes)
