Please Get Out of My Family

Favey Croshe founded her house on an agreement with elemental kings, giving her descendants elemental affinity...all except Winadella, that is. When Winny is kicked out of the house for being useless, Favey awakens from a 300-year death to possess Winny and help her get revenge on the family who cast her out like trash. Luckily, one of her old pupils, the half-dragon Wallika, is willing to help his master humble the arrogant elementalists and...maybe even offer Winny a new home. Source: Tapas
