Kenta Usui

Birthdate: February 29 1988 Height: 180cm Weight: 70kg Kenta Usui is a student that transferred to Karins high school. He is also her workmate. Kenta is the only human that knows of Karins vampiric nature. He learned what she was after witnessing her biting three victims one of which was his own mother. He has promised to keep this knowledge a secret. As his unhappiness causes Karins blood to rapidly increase she has taken it upon herself to cheer him up by making him a bento every day. He could not afford to buy his own lunch and is therefore grateful to her. Source: Wikipedia
