Haimiya Is Scary Cute First Anniversary Illustration

Haimiya Is Scary Cute Marks One Year of Serialization
On November 6, 2026, the official Haimiya Is Scary Cute team celebrated one year since Sumu Kamiyama's manga began serialization.
The series originally launched on Manga UP! on November 6, 2025. Since then, the relationship between Haimiya and Kurose has continued to develop through the digital manga platform operated by Square Enix.
To commemorate the occasion, Kamiyama created a special illustration shared through the manga's official X account. The artwork serves as a thank-you to readers who have supported the series throughout its first year.
The announcement specifically celebrates the first serialization anniversary. It does not announce an anime adaptation or the conclusion of the manga. The series remains ongoing, with its fourth collected volume released on the same date as the anniversary.
New Artwork Features Haimiya and Kurose Together
The first-anniversary illustration depicts Haimiya and Kurose wearing dark school uniforms with white trim and school emblems on their jackets.
Haimiya appears with long silver-gray hair and a bright smile while putting her arms around Kurose from behind. Kurose, recognizable by his dark blue hair, smiles with a slightly embarrassed expression.
The upper portion of the artwork includes the Japanese anniversary message 「連載1周年!」. Kamiyama also added a thank-you message, a personal signature, and the date November 6, 2026.
The illustration highlights the central relationship that defines the manga: a senior girl whose intimidating appearance contrasts with the warmth she shows her younger schoolmate. It is special commemorative artwork created by the manga's author, not a new book cover or an anime key visual.
A Romantic Comedy About a Scary-Looking but Sweet Senior
Haimiya Is Scary Cute follows Kurose, a high school boy who attends the same school as an older student named Mio Haimiya.
Haimiya is widely regarded as intimidating. She stands out because of her gray wolf-cut hairstyle, multiple piercings, and blunt Kansai dialect, giving other students the impression that she is difficult to approach.
Kurose, however, experiences a very different side of her. Haimiya treats him with unexpected kindness and attention, leading him to gradually realize that her personality is far more nuanced than her reputation suggests.
The manga builds its romantic comedy around the contrast between outward appearances and genuine feelings. Everyday encounters, embarrassment, and the characters' changing emotions shape their developing relationship throughout the story.
Volume 4 Releases on the First Anniversary
Alongside the anniversary celebration, Square Enix published Haimiya Is Scary Cute Volume 4 on November 6, 2026, under the Gangan Comics UP! imprint.
According to the official Volume 4 synopsis, Kurose begins questioning his feelings toward Haimiya. Koyuki, one of Haimiya's classmates, directly asks whether he has romantic feelings for the older student.
Although Kurose feels his heart race whenever he is around Haimiya, he remains uncertain whether those feelings amount to love. Encouraged by Koyuki, he starts searching for a way to attract the senior's attention.
Meanwhile, Haimiya finds herself in an unexpected situation that requires her to wear a maid outfit. This is one of the developments highlighted by the publisher, although readers will need to follow the original manga for the complete sequence of events.
The standard edition is priced at 792 yen including tax, uses a B6 format, and carries ISBN 9784301008668.
Volume 4 Special Edition Includes a Full-Color Booklet
For the first time in the series, Square Enix also released a Haimiya Is Scary Cute Volume 4 special edition featuring an additional full-color illustration booklet.
The booklet contains 44 full-color pages and more than 45 illustrations by Sumu Kamiyama. The contents include new artwork created specifically for the special edition, alongside color illustrations that had not previously appeared in the collected manga volumes.
The illustrations feature Haimiya in different outfits, including her school uniform and street-style clothing. The booklet also comes with newly drawn cover art featuring decorative silver details.
The special edition costs 1,518 yen including tax, uses a B6 format, and has ISBN 9784301008675. The booklet is an exclusive feature of this edition and is not automatically included with the standard Volume 4 release.
Manga Continues with an Official English Edition
Haimiya Is Scary Cute remains in serialization through Manga UP!, Square Enix's official digital manga platform.
The Japanese series page lists Thursday updates, allowing readers to follow the continuing relationship between Haimiya and Kurose. Early chapters are accessible through the official service, while later chapters are available according to its reading system.
The manga also has an international release under the official English title Haimiya Is Scary Cute on Manga UP! Global, giving English-language readers access to the story through Square Enix's digital platform.
Since serialization began in November 2025, the series has produced four Japanese collected volumes within its first year. As of the anniversary announcement, neither an anime adaptation nor a Volume 5 release date has been officially confirmed.
Why This Matters
1) Four collected volumes coincide with the first anniversary
Since launching in November 2025, Haimiya Is Scary Cute has reached four printed volumes. Its first anniversary and the release of Volume 4 represent two distinct milestones occurring on the same day.
2) The artwork emphasizes the central relationship
Kamiyama's illustration shows Haimiya affectionately embracing Kurose, highlighting the warm interactions that define the romantic comedy. It offers new celebratory artwork without implying an unannounced anime or media adaptation.
3) The special edition showcases the creator's illustrations
The full-color booklet containing more than 45 illustrations gives readers access to additional Kamiyama artwork beyond the standard manga pages, including illustrations not previously collected in the regular volumes.
