Shinichi Katori

He is a spontaneous boy who appears whenever love advice is needed. He is from class 3-5 and is the president of the drama club. Shinichi is a quirky and upbeat teenager. He tends to speak in short English phrases at times; he also tends to be a playboy around girls (though he may not be aware how much it affects their feelings) and even calls himself a "Dating Master" and "Love Master", much to everyone's annoyance and amazement.

In a later chapter, it is revealed that Shinichi has been fighting an illness that causes him to cough up blood. Because of this, he has been repeating years at high school. So many times in fact, that he originally attended high school even before the current third years began high school.
