Shinnosuke Nekota

The main protagonist of the story, from the very beginning, it is shown that Nekota is an energetic and slightly perverted troublemaker; he constantly tries to get a peek of girls panties through low angles and directly pulling skirts up. He has a genuine crush on his 'rival' Hoshino Sakura and confesses to her prior to finding out the fact that Sakura will most likely become his step sister. Neko keeps his heart set on Sakura throughout the plot being tempted by many girls who have all fallen for him.

Socially, Nekota is seen as the most popular to the guys but is generally detested by the girls who are in his class. Nekota was convinced to join the school's baseball team and turned the team around, his involvement in the team resulted in both one-year-older and one year younger team managers to fall in love with him.
