Shousuke Samon

Shousuke Samon is a main character of the Samon-kun wa Summoner manga. He entered Solomon High as a transfer student in class 2-B.

Samon claims to hate good people, as he believes them to be hypocrites that hide their greed, being that the reason why he started bullying Sakura Teshigawara. Instead, he likes "greedy people" who are honest with themselves and with their desires. Ironically, this has lead him to act kindly, as when he helped Kotori Kago deal with her mother's controlling nature, stating that Kotori had a "pure" greed (her desire to hang out with her friends) that made him like her.

He is a sadist, and loves to torment people, particularly those who are hardworking and good, like Teshigawara. It is constantly shown that when faced with a challenge, he will always try to use demons or cheap tactics to win, though they usually backfire; and when this happens, he will shamelessly beg for forgiveness. He is extremely arrogant due to his high intelligence, but because of this, he is not very popular with his peers, and has trouble socializing, though he doesn't care much about it.

Despite all of this, he usually keeps a cheerful and carefree disposition, and smiles constantly. Samon is very competitive, though his poor physique usually gets in the way of his plans. He likes cats and sweets and has a fear of insects.
