Characters

The names and nicknames of all the characters are puns and allusions to the central "quirk" of their personality. For example, the name Lily is a hint of a lilies, whose Japanese title "yuri" is also used to refer to lesbian love in Japanese pop culture.

Nozomu "Baka" Tanaka (田中望, Tanaka Nozomu): Voiced by: Chinatsu Akasaki^[1] (Japanese); Elissa Cuellar^[4] (English); Portrayed by: Yui Okada (2020 drama)^[5]; The central character and an incredibly stupid girl. Her stupidity and annoying behavior is so remarkable that even close friends call her "Baka", which means "idiot" in Japanese.
Akane "Wota" Kikuchi (菊池茜, Kikuchi Akane): Voiced by: Haruka Tomatsu^[1] (Japanese); Luci Christian^[4] (English); Portrayed by: Yuri Tsunematsu (2020 drama)^[5]; An aspiring manga artist and a fan of yaoi media. It is implied that she is developing feelings for her teacher Waseda, but is in denial about it. She also listens to the music of the Vocaloid producer Teishotoku-P, who unbeknownst to her is actually someone she knows.
Shiori "Robo" Saginomiya (鷺宮しおり, Saginomiya Shiori): Voiced by: Aki Toyosaki^[1] (Japanese); Genevieve Simmons^[4] (English); Portrayed by: Yurika Nakamura (2020 drama)^[5]; An emotionless smart girl who aspires to be a microbiologist. She is childhood friends with Baka and Wota, whom she met while in elementary school. She went to the same junior high school as Majime.
Saku "Loli" Momoi (百井咲久, Momoi Saku): Voiced by: Maria Naganawa^[1] (Japanese); Hilary Haag^[4] (English); Portrayed by: Mei Hata (2020 drama)^[5]; A short girl who looks like a primary school student. Her appearance is ironically combined with her childhood innocence, which is why Loli is constantly becoming a victim of "adult" misunderstandings. She lives with her grandmother as her parents are working overseas in Germany.
Minami "Yamai" Yamamoto (山本美波, Yamamoto Minami): Voiced by: Miyu Tomita^[1] (Japanese); Maggie Flecknoe^[4] (English); Portrayed by: Momoko Fukuchi (2020 drama)^[5]; A girl with a chunibyo personality, who dyed her hair blond. She often speaks with Waseda regarding her thoughts and plans.
Kanade "Majime" Ninomae (一奏, Ninomae Kanade): Voiced by: Rie Takahashi^[1] (Japanese); Kira Vincent-Davis^[6] (English); Portrayed by: Nana Asakawa (2020 drama)^[5]; Tomboy-ish shy girl who is incredibly popular with others because of her masculine appearance, but she herself doesn't notice it because of her social clumsiness. Thanks to her outstanding logical thinking, Majime is incredibly talented in mathematics, but at the same time completely ignorant in ordinary human relationships. For this reason, she admires Robo incredibly, who she considers equally smart and sociable.
Hisui "Majo" Kujyō (久条翡翠, Kujō Hisui): Voiced by: M.A.O^[7] (Japanese); Christina Kelly^[4] (English); Portrayed by: Ayaka Imoto (2020 drama)^[5]; A student who rarely comes to school and who has an interest in the occult. She has a twin sister named Kohaku.
Lily Someya (染谷リリィ, Someya Rirī): Voiced by: Satomi Satō^[7] (Japanese); Skyler Sinclair^[4] (English); Portrayed by: Yui Kobayashi (2020 drama)^[5]; A popular beauty and part-Austrian student who transferred to the school. Her role in the plot is a parody of lesbian characters, although it is unclear how much this is connected with her real sexuality or just phobia for men, which for some reason affects Tanaka too. One way or another, Lily becomes one of the most popular girls of their school, although her life is often complicated due to the quirks of other characters.
Masataka "Waseda" Sawatari (佐渡正敬, Sawatari Masataka): Voiced by: Kazuyuki Okitsu^[7] (Japanese); Scott Gibbs^[4] (English); Portrayed by: Keita Machida (2020 drama)^[5]; The class's homeroom teacher. He is only attracted to female university students. He also regularly has consultations with Yamai; a running gag involves his glasses breaking when Yamai mentions something regarding her chunibyo behavior. Outside of school, he is secretly a Vocaloid producer who goes by the name Teishotoku-P (低所得P, Teishotoku Pī).
Rie "USB" Mikami (三上理恵, Mikami Rie): Voiced by: Sayaka Senbongi (Japanese); Avery Smithhart^[4] (English); Portrayed by: Nazuna Iseri (2020 drama)
Kohaku Kujyo (久条琥珀, Kujō Kohaku): Voiced by: Reina Ueda (Japanese); Chaney Moore^[4] (English); Portrayed by: Noa Kita (2020 drama)^[5]; Majo's twin sister. Unlike her sister, she is the complete opposite.
Airi "Nora" Nobara (野原愛莉, Nobara Airi): A high school girl who has poor social skills. She lives alone due to a desire to own cats, which could not be done in her parents' residence. She also works part-time as a convenience store clerk.
Utako "Hime" Nakamura (中村詩子, Nakamura Utako): A high school girl who is the daughter of a ramen shop owner. She is known in school for keeping a cute personality, and she also posts videos about fashion online. When she was in junior high school, she was frequently bullied for having an unattractive appearance. She then met Baka, who then gave her the nickname "Hime" and helped inspire Hime's father to improve their restaurant business, which was failing at the time.
Shiikyon (シーキョン, Shīkyon): Voiced by: Kaori Nazuka (Japanese); Olivia Swaysey (English); Portrayed by: Risa Naito (2020 drama); The school's nurse on duty and fellow chunibyo of Yamai.

Masayoshi Suzuki (鈴木正義, Suzuki Masayoshi): Voiced by: Junichi Yanagita (Japanese); Blake Weir (English); Portrayed by: Ryo Yokoyama (2020 drama)
