TV-Series
Description
Aiko Kudō attends Fumizuki Academy as a top-ten academic achiever in Class 2-A, having transferred near the end of her first year. She stands approximately 5'2" tall, taller than Mizuki Himeji and about the same height as Minami Shimada, weighing 46 kg, with light green hair styled in short spikes and hazel eyes.

Her personality is friendly, easy-going, and mischievous. She refers to herself using the masculine pronoun "boku" and delights in playful teasing, particularly targeting Akihisa Yoshii and Kouta Tsuchiya with perverted remarks that often cause comical nosebleeds. Her interactions suggest a romantic interest in Kouta, evident in Season 2 when she attempts to attract his attention in a bathing suit. Unlike other female classmates, she does not intentionally inflict physical harm on male students.

Aiko excels with electronic gadgets, frequently using a micro-recorder to capture and manipulate conversations, editing them to create misunderstandings, often targeting Akihisa for comedic effect. Her practical learning style contrasts with Kouta’s theoretical approach, especially in subjects like physical education and health, where she emphasizes hands-on experience over note-taking.

Her summoned being, a Shoukanjuu, wears a sailor-style school uniform and wields a battle axe augmented with electrical accessories. In its occult form, it manifests as a Noppera-bou—a faceless entity—which Yuuji Sakamoto interprets as symbolizing her desire to conceal her true self.

Aiko disregards Fumizuki Academy's hierarchical class divisions, socializing freely across classes. Within Class 2-A, she maintains friendly relationships with Shouko Kirishima and Yuuko Kinoshita. Her dynamic with Kouta extends beyond teasing; light novel volumes depict simulated scenarios where they have a son who inherits Aiko’s appearance and Kouta’s eyes. This son exhibits a serious demeanor but shares Aiko’s tendency toward eroticism. Another simulated future suggests she aspires to become a doctor.

Her name, Aiko Kudō, combines "Kudō," meaning "worker" and "wisteria," with "Aiko," meaning "love child."
