The main character and a first year high school student. He aims to attend medical school after graduating from high school. Eita is very smart and always places at the top of the class during term exams. He doesn't like romance and love, as he calls himself "anti-romance." However, there is a reason for this: his parents divorced to search for 'the real one' and left him alone, never appearing before him again. This is why he lives with his aunt, Saeko-san.
