Hideki Mizuguchi

Hideki Mizuguchi (みずぐち ひでき) is the lead delinquent in Nagisa Shiota's Class 3-5 in Paradise High School.

Appearance/Personality
Like most of his classmates, Hideki sports a black jacket over a patterned shirt along with black pants as part of his school uniform. Hideki has a pair of eyes with small pupils and has short black hair with the top part combed backwards.

Hideki does not like being ordered around by someone he sees as physically weaker than him, but he will yield if he were to be bested, notably shown when he meets his teacher Nagisa for the first time.

Plot
After letting Nagisa get mocked by his classmates, Hideki rose from his seat to threaten Nagisa not to order them around, or he would be killed. At that point, his teacher used the Stun Clap on him, maneuvered around Hideki and held him still with his middle finger poking at his neck. Shocked by the sudden turn of events, Hideki is wished good luck by Nagisa before class began.

Some time later outside, Hideki barked at a napping Nagisa to wake up and added that he and class only went outside because Nagisa wanted to study there.

Trivia

 * It takes two hours for Hideki to style his hair.
