Mikaru also seems to be a sickly girl, collapsing to the floor every time Michel appears somewhere else or when Kaito is near Lucia (in order to keep Kaito to herself). In the manga, when Kaito states that he loves only Lucia and could never love Mikaru the way that she "loves him", Mikaru takes off her clothes and offers herself to him in desperation of keeping him; Kaito turns away from her and leaves.
