Mochizuki, Kotarou

望月コタロウ

As the younger brother of Jirou Mochizuki, he does not appear to display vampire abilities like the "Hide Hand." However, he seems to possess an exceptionally high pain tolerance, as he is thrown into the ground and walls without injury in nearly every episode. Mimiko Katsuragi notes that he does not look like Jirou's brother because, unlike Jirou, he is not harmed by sunlight or water. Furthermore, they look completely different: Jirou is tall with black hair and brown eyes, whereas his brother is short with blond hair and blue eyes. Kotarou explains that they are brothers because they are the last two surviving vampires of their unique bloodline. Both wear goggles around their necks. He shares the same speech pattern and bears a striking resemblance to Jirou's former lover, Alice.
