Toilet-Bound Hanako-kun Season 1: A Spirited Dive into Supernatural School Mysteries

Toilet-Bound Hanako-kun (known as Yako-sen no Hanako-kun in Japanese) is a captivating anime adaptation of the manga by Iro Aida, which premiered its first season on January 9, 2020, and ran for 12 episodes. Produced by Lerche, this supernatural comedy-mystery series blends vibrant visuals, quirky humor, and heartfelt moments, creating a unique addition to the anime landscape. Season 1 introduces viewers to the whimsical yet eerie world of Kamome Academy, where rumors of supernatural “Seven Mysteries” intertwine with the lives of its students, particularly Nene Yashiro and the ghostly Hanako-kun.

Plot Overview

The story centers on Nene Yashiro, a first-year high school student at Kamome Academy, who is obsessed with romance and dreams of finding the perfect boyfriend. Desperate to make her crush notice her, Nene turns to a school legend: the ghost of Hanako-san, the seventh of Kamome Academy’s Seven Mysteries, said to haunt the third stall of the girls’ bathroom on the third floor of the old school building. According to the rumor, Hanako-san grants wishes in exchange for a price. When Nene summons Hanako, she’s shocked to discover that Hanako is not a girl but a mischievous boy ghost named Hanako-kun, who wields a kitchen knife and a playful demeanor.

After a wish gone wrong leaves Nene spiritually bound to Hanako, she becomes his assistant, helping him maintain balance between the human and supernatural worlds. Alongside Hanako and later Kou Minamoto, a second-year student from a family of exorcists, Nene navigates the mysteries of Kamome Academy. Each episode unveils layers of the Seven Mysteries, from a ghostly broadcasting room to mischievous Mokke creatures, while hinting at deeper secrets about Hanako’s past and the school’s supernatural underpinnings.

Characters

The charm of Toilet-Bound Hanako-kun lies in its colorful cast:

• Nene Yashiro: The optimistic, romance-obsessed protagonist whose impulsive wish drags her into the supernatural. Her kind heart and determination make her endearing, even if her naivety often lands her in trouble.
• Hanako-kun: The enigmatic ghost of the seventh mystery, Hanako is equal parts playful and mysterious. His cheerful facade hides a darker past, making him a compelling figure.
• Kou Minamoto: A brash but kind-hearted exorcist-in-training who initially aims to exorcise Hanako but becomes an ally. His loyalty and courage add balance to the trio.
• Supporting Cast: Characters like Tsuchigomori (the fifth mystery and a chain-smoking librarian spider), Mitsuba (a tragic ghost with ties to Kou), and Sakura (a mysterious upperclassman) enrich the story with their own secrets.

Themes and Tone

Season 1 masterfully balances lighthearted comedy with darker, emotional undertones. The show explores themes of regret, redemption, and the consequences of wishes, often through the lens of the supernatural. Hanako’s playful antics and Nene’s romantic daydreams provide humor, while glimpses into Hanako’s past and the tragic fates of other spirits add depth. The series also touches on friendship and trust, as Nene, Hanako, and Kou form an unlikely but heartfelt bond.

The tone shifts seamlessly between whimsical (e.g., Nene’s misadventures with a mermaid curse) and poignant (e.g., Mitsuba’s heartbreaking arc). This blend keeps viewers engaged, as the show never lingers too long in one mood.

Animation and Art Style

Lerche’s animation is a standout feature, with a vibrant, almost storybook-like aesthetic that mirrors the manga’s distinct style. The use of bold colors, exaggerated expressions, and chibi-style interludes enhances the comedic moments, while darker scenes employ shadowy palettes and eerie designs to evoke unease. The supernatural entities, like the Mokke or the Hell of Mirrors, are creatively designed, blending cute and creepy elements.

The opening theme, “No.7” by Yoji Ikuta, and the ending theme, “Tiny Light” by Akari Kitō, perfectly capture the show’s mix of mystery and emotion. The soundtrack, with its playful and haunting melodies, complements the narrative’s shifting tones.

Highlights of Season 1

• World-Building: The Seven Mysteries provide a rich framework for storytelling, with each mystery revealing more about Kamome Academy’s supernatural lore.
• Character Dynamics: The chemistry between Nene, Hanako, and Kou drives the series, with their banter and growth keeping the audience invested.
• Mitsuba’s Arc (Episodes 8–9): This emotionally charged storyline showcases the show’s ability to tackle heavy themes like loss and identity.
• Cliffhangers: The season ends with tantalizing questions about Hanako’s past and his connection to a mysterious figure, setting up anticipation for future adaptations.

Reception and Impact

Upon its release, Toilet-Bound Hanako-kun Season 1 was praised for its unique blend of genres, striking visuals, and faithful adaptation of the manga. Fans lauded the chemistry between characters and the balance of humor and heart, though some noted that the 12-episode run felt rushed, leaving certain plot points unresolved. The anime boosted the manga’s popularity, drawing new readers to Iro Aida’s work.

The series also spawned a passionate fanbase, evident in fan art, cosplay, and discussions on platforms like X, where users celebrated its quirky charm and emotional depth. However, some fans expressed disappointment over the lack of a confirmed second season by 2025, though a reboot project, After-School Hanako-kun, and a short film have kept the franchise alive.

Conclusion

Toilet-Bound Hanako-kun Season 1 is a delightful mix of supernatural mystery, comedy, and emotional storytelling. Its vibrant animation, memorable characters, and intriguing world-building make it a standout in the 2020 anime lineup. While the season leaves viewers craving more answers about Hanako’s past and the Seven Mysteries, it succeeds as a self-contained adventure that invites you to laugh, cry, and ponder the cost of wishes. For those seeking a blend of spooky and sweet, Kamome Academy’s haunted bathroom is well worth a visit.
