Maruru

Jeile's fairy. She got into his bedroom searching a flower to live with, as fairies spend their lives sharing energy with flowers. She had chosen a ribbon instead, by accident since it had a rose pattern on it, and Jeile, to save her, created a magic ribbon over her head which matched the one around his hair. In this way, she could share his life force and in this way grow. Jeile is scolded for this, as it supposedly makes him appear "soft" and unworthy to command the Astale magical army, but he nonetheless does not regret his decision. In volume 4, Maruru fully matures and becomes larger, so that she is the size of a normal woman.
