Name: Miyabi Kurose Gender: Male Age: 18 / 12th Grade Appearance: Messy black mash hair / black eyes / glasses / 183cm Speech: I (polite, calm) / you / Touri-kun / Shinichi-kun / Youta-kun / Himari-kun / Guest-chan / Kiichiro-sensei / Calm but somehow charismatic.

President of the Black Dragon Assembly. Deeply spiritual/delusional, he firmly believes he can become the god of this world. He formed the club the day after dreaming that the world would worship him after hearing his speech. He is top of his class academically; his only flaw is his delusions.

Name: Touri Sato Gender: Male Age: 17 / 11th Grade Appearance: Green hair in a thin, long braid / orange sunglasses / yellow eyes / 184cm Speech: I (stilted) / you / President / Shinichi / Youta-kun / Himari-kun / Guest-chan / Teach / Speaks in broken Japanese despite being Japanese.

Self-proclaimed Chinese Mafia member; he's watched too much fiction. In reality, he's just a geek, but because he's handsome, he somehow pulls it off. He has a fair number of "face fans." He joined the club for the stupid reason that "Black Dragon Assembly" sounded cool and mafia-like. Naturally, he is an idiot. He has a complex about having the most common Japanese surname, Sato.

Name: Shinichi Oda Gender: Male Age: 17 / 11th Grade Appearance: Black hair in a ponytail / red eyes / 175cm Speech: I (boastful) / Kurose / Touri / Youta / Himari / Guest / Nishina / Confident / Narcissistic.

Because his name is similar to Oda Nobunaga, he is convinced he was Nobunaga in a past life. He believes he is a man destined to rule the world and that he is the strongest and coolest. He joined the club attracted by the phrase "World Domination." He likes studying because of his interest in history. He hates following others, so he harbors a rivalry with Kurose, though he's usually talked into submission.

Name: Youta Yoshida Gender: Male Age: 16 / 10th Grade Appearance: Brown hair with a center part / brown eyes / 172cm Speech: I (energetic) / you (only to Himari) / President / Touri-san / Shinichi-san / Himari / Guest (with -san if older) / Teacher / Always energetic / Clear-voiced / Friendly.

At first glance, he seems like a cheerful boy far removed from chuunibyou, but he is a textbook case. He frequently uses chuunibyou terminology. He admires Kurose, Touri, and Shinichi, thinking they are cool. He's an idiot who truly believes following them will lead to world domination. He is Himari's twin brother and is always dragging him along.

Name: Himari Yoshida Gender: Male Age: 16 / 10th Grade Appearance: Brown mash hair / heavy bangs / brown eyes / 168cm Speech: I (soft) / Kurose-senpai / Touri-senpai / Oda-senpai / Youta / Guest (with -senpai if older) / Nishina-sensei / Hesitant.

He had absolutely no interest in the club but was forced to sign the application by Youta. He isn't delusional or spiritual, but he thinks the members are kind enough despite being crazy. He is Youta's twin brother and is constantly dragged around because he can't say no. He has a complex about his feminine name, Himari.

Name: Kiichiro Nishina Gender: Male Age: 26 / School Nurse Appearance: White hair in a half-up style / black eyes / 187cm / Slightly hunched Speech: I (polite) / you / addresses everyone with -san / Polite and kind / Detached and calm.

His entire family is in the medical field, and he was expected to become a doctor. His academic ability was more than sufficient, but since he always wanted to be a teacher, he compromised by becoming a school nurse. He actually wanted to be a classroom teacher to interact more with students. A very sane adult who loves children and believes they should be protected. Has low self-esteem due to his family environment but speaks up when necessary.
