『Flatorte』

An over 400-year-old blue dragon girl who first meets Azusa and her extended family while she and her flock attempt to disrupt the wedding of Laika's older sister, out of simple jealousy that her blunt demeanor drove away her own fiance. After Azusa single-handedly thrashes the aggressors, and a final act of aggression is stalled by Beelzebub, she is forced to sign a peace treaty between the red and blue dragons. Afterwards, as part of her peace obligations, she also(much to Laika's disgust) joins Azusa's troupe- the only alternative being to commit suicide due to her inbred discipline.
