Kenji Nojima (anime)
He has brown eyes and short, curly, and light brown hair. He is usually seen wearing a purple woolen vest over his normal school uniform. In addition, he wears his student council red and white striped armband on his left arm. He is noted to be charming and handsome.
He is generally a calm person who serves as a balance in the student council. He has an extremely low tolerance for alcohol – so much so that even just the smell of it can make him drunk. Shinba is very popular with girls and calls them "my little kittens. He enjoys the attention from his fans. As demonstrated during graduation and student council's message game, he is prone to crying. When he is about to step down from the Student Council (at that time, Kikuno Asahina was saying 'Good luck, dumb senior,'), he is shown to be turning his face and trying not to cry, thus earning him a sarcastic comment from Agata. He demonstrates pride in his title: magician of love. He proves that he can fix romance problems when attempting to rewrite Sōjirō's misunderstandings in the Saaya love diagram issue.
- He's good at analyzing people's romance problems and elaborating it to their specific need (and he's usually right).
- He's also good at cooking.
