The happy go lucky servant to the Kirishiki family. However, there's more to him then meets the eye...

Tatsumi is a special kind of vampire called "Jinrou", who can withstand the sunlight unlike other Shikis and is very difficult to kill. He's a sadistic individual and enjoys tormenting his victims. He also acts as the commander of the Shiki-turned villagers. He has a great respect for Sunako.
