Shouma Ojiro

Shōma is Kazuma's younger brother. He's also a student at Kumaneko High School. He's very popular among the girls at school. Though due to his cold and rude attitude, they call him "Ice Prince". Shōma originally didn't believe that Fumino is a girl. He finally believes it after seeing her underwear. He once tried to bribe or supposedly give Fumino money to live comfortably until she graduates, in exchange for leaving Kazuma. However, she smacks it away and called him an idiot for thinking that she will leave him for money. Despite being brothers, Shōma and Kazuma have different mothers, but they do talk to each other in polite terms. Since Kazuma had left the family, Shōma had to take over his responsibilities. He also insults Kazuma for becoming a teacher, claiming it's below his social status. Apparently, he doesn't know when Kazuma's birthday is, which shocked Fumino. He goes on to tell her that it isn't celebrated in the Ojiro household. He loves his brother very dearly although he doesn't really like to show it. (Source: Wikipedia)
