An alien from the planet Vulcan, Yomi is a sweet being who fell in love with Yoru from the moment she met him. Though her behaviours can be strange, and she has a hard time understanding the cultural idea of being one's own self, she does her best not to cause any trouble to her friends. Comes from a culture where her and her siblings obey one overlord, so she often watches what she says or does. Uses claws to fight.
