Shiki is the lead vocalist of his high school's music club that later forms into a five-men idol band. He is a very energetic boy who loves to sing and loves his high school buddies, so rather than going their separate ways after graduation, Shiki intends to mastermind their debut as an idol unit. He also tends to add "honkii" or "mega" to any descriptor he uses, and ends all of his sentences with す（ssu).

He refers the Producer as "Producer-chan" and his buddies by their given name in katakana plus "cchi", though he also refers [Hayato Akiyama](https://anilist.co/character/123624) as "Hayato Senpai". He's not the best at academics, so he studies with his buddies a few days before exams.

In the anime, it's revealed that Shiki thinks that he isn't good at anything except singing, and in middle school, he would spend all of his free time at karaoke. However upon meeting HighxJoker at his first year entrance ceremony in high school, and seeing them perform, he became inspired to do something with his youth and begged Hayato to let him join the band.

Shiki is a fan of spicy food and candy, and is always seen with mascot character Kumacchi, either on his clothes, phone, or as a plush.

Doujima is a first-year high school boy and a member of the student council.

Low-level yakuza and underling of Sakyo Furuichi, who he calls "aniki" or "bro". He's extremely devoted to Sakyo, and is often seen helping him with various tasks and hanging around the company. As a result, he gets quite familiar with the members of MANKAI.

Sadaharu is a close friend of [Jirou Yakuin](https://anilist.co/character/191673/Jirou-Yakuin), being one of the few people Jirou is comfortable being open around. He is paired with Satsuki Kaneyama in their school's Marriage Practical.

Sadaharu is portrayed as being a mild mannered and eccentric otaku who enjoys reading manga, watching anime, and playing video games. Like Jirou, Sadaharu also has lousy luck with women, preferring the women to be "2D" instead of real so they can't end up hurting his feelings. However, it appears that he and his practice partner get along well which indicates that the practical has somewhat improved his social skills with women. Sadaharu is considered to be the series primary comic relief character, having a knack for making light of serious situations by comparing them to similar events found in many Japanese media and pointing out common tropes. He often showcases incredible creativity by imagining himself or others in fictional circumstances that almost appear to break the laws of reality, with his rampant imagination even causing him to the break the 4th wall on a few occasions. Despite his absurd antics, Sadaharu is ultimately a good, kindhearted person and will go out of his way to help and support those he cares for when he sees fit.
