Kumamine Puts a Cute Spin on Jujutsu Sorcerers
Bandage manufacturer Hakujuji has announced a new collaboration campaign pairing its FC Kizu Shochi wound care line with the Jujutsu Kaisen anime. The hook: all eight character illustrations are drawn by Kumamine, the Kyushu-based illustrator and manga artist best known for creating Phone Cat and Work Cat, two characters that became some of the most recognizable memes on Japanese social media.
Kumamine's signature style skews cute and comedic, so seeing Yuji Itadori and company filtered through that lens is the main draw here. The campaign covers nine products across 43 SKUs in Hakujuji's wound care lineup, from large adhesive bandages to gauze and wrapping bandages. A battle anime about cursed spirits and the sorcerers who fight them partnering with a first-aid brand is a pitch-perfect pairing, and Hakujuji knows it. The company has run the same promotion format annually with a different anime each year: Demon Slayer in 2020, Haikyu!! in 2023, Blue Lock in 2024, and Wind Breaker in 2025. This marks Jujutsu Kaisen's second Hakujuji tie-in after an initial 2021 campaign.
How the Campaign Works
Customers buy eligible FC Kizu Shochi products at retail, photograph the receipt, and submit it through Hakujuji's official LINE account. Each product earns one point. There are two tracks:
Guaranteed Course: Buy any two items from the FC Moist Healing Pad or FC Moist Sheet lines (2 points). Choose one of four Kumamine-illustrated sticker sets, each containing two stickers.
Lottery Course: Accumulate points from seven other eligible products for a shot at bigger prizes:
- 3 points: original QUO prepaid card worth ¥5,000 (100 winners)
- 2 points: original T-shirt and pin badge set with all eight character designs (100 winners)
- 1 point: mini acrylic stand set of all eight characters (300 winners)
Postcard entries are also accepted for those who prefer analog. The campaign site has full product details and entry instructions. Receipts must be dated between June 16 and September 15, 2026, with the LINE submission deadline set at September 8.
Why Kumamine Matters
For readers outside Japan, Kumamine may not ring a bell by name, but there's a good chance you've seen the art. Phone Cat (電話猫) started as a simple illustration of a cat on a phone call, and its offshoot Work Cat (仕事猫) became a workplace safety meme icon across Japanese internet culture. The cat, wearing a hard hat and cheerfully approving obviously dangerous situations, has appeared on official safety posters, capsule toys, and countless parody images. Seeing those characters' sensibility applied to Jujutsu Kaisen's cast of cursed-energy fighters is the kind of tonal mismatch that makes collaboration merch fun.
Looking Ahead
Jujutsu Kaisen Season 3 adapted the first half of the manga's Culling Game arc, airing on MBS/TBS in Japan from January through March 2026. The second half is expected in the Summer 2026 anime season. Crunchyroll holds international streaming rights for the series, with all Season 3 Part 1 episodes currently available.
The campaign itself is Japan-only. Hakujuji's FC Kizu Shochi products are sold at domestic drugstores and retailers, and both the LINE entry system and the postcard option are designed for Japanese addresses. International fans looking to pick up the Kumamine-illustrated goods will likely need to use a proxy purchasing service.
Gege Akutami's original Jujutsu Kaisen manga ran in Shueisha's Weekly Shonen Jump from 2018 to 2024 and has surpassed 150 million copies in circulation worldwide. A spinoff manga, Jujutsu Kaisen ≡ (Modulo), with art by Yuji Iwasaki, ran as a short serialization in the same magazine starting September 2025.
