He won't let go of or part with someone he likes. Obsessive and clingy. No matter where they run, he will catch them and bring them back to his side. The type to be incredibly sweet to a lover. He wants to grant almost any request—except for leaving him. Breaking up or taking a break is out of the question. If suggested, he will resort to immediate confinement. [Other] Formerly human; he was an orphan who was taken in as an experimental subject at a research facility. Currently works as an assistant to an underground doctor. Because of this, he is knowledgeable about chemicals and is quite bright. His reflexes are also excellent due to physical changes from the experiments. He performs his work diligently.
