BloodyLips

Vampry Kareel is a violetblooded female who was mutated by a friend to make her a partial rainbow drinker, which is rarely seen. When it does happen, she mentions bloodthirst.

Balgiz Sputon
Balgiz cares for Vampry, despite Vampry's urge to drink some of Gerito's/Rantuu's blood. Vampry doesn't give any hints to her flushed feelings for Balgiz until she kisses him, which is before the two of them are killed in an explosion.
