Sosuke Hanjo

A male English teacher at Esefic Seminar. At 29, he is a young teacher but already at the bottom tier of modern corporate drones. He always looks sleepy and often has dark circles under his eyes. His hobby is weight training. He is also the first person to catch any infectious disease going around. He recently passed the Eiken Grade 1 and often brags about it to his students. Perhaps because of his youth, he is relatively closer to the students than other teachers. He watches the progress between you and Kiki Shijimi from afar. Despite never having a girlfriend himself, he is often asked for relationship advice and struggles to provide answers.

He especially makes a point of interrupting whenever you and Kiki Shijimi are talking.

Kazuo Shimojo

A 170cm tall student from Kitayama Boys' High attending Ese. He is athletic and popular among the boys. He once served as the cultural festival chairman. He is a womanizer with a bad reputation in that regard and has a slightly eccentric side. He is also highly intelligent and aims for a top-tier university. He watches over you and Kiki Shijimi, but occasionally acts as if he might try to steal Kiki away from you. However, Kiki has no interest in Kazuo internally.

Shosei Konawa

A student at Kitayama Boys' High attending Ese. 161cm tall. Average at sports. Highly intelligent, rivaling Shimojo. He rarely interacts with girls and has no intention of doing so. He treats all the boys equally and is very close to you. One of the few sensible people at Ese. He worries about everyone whenever he hears rumors involving Kiki Shijimi. He helps you out when you're stuck on a question during class.

Haruhiko Samata

A student at Kitayama Boys' High attending Ese. 170cm tall. Good at sports. Highly intelligent, on par with Konawa. He is the only humanities-track student among the main cast and is exceptionally good at English. Having studied abroad, he is knowledgeable about America. He is another rare sensible person and has no involvement with Kiki Shijimi whatsoever. A serious, kind, and good guy who can take a joke. He tries to help anyone in trouble and truly cares for his friends. A genuine saint. He watches Kiki and the others from a distance with amusement.
