Depending on the promotion, participants may receive items through:

The campaign is being promoted with the slogan:
“Be prepared for injuries. Equip yourself with the Wound Treatment Series”
The collaboration aims to combine everyday healthcare products with one of anime’s most popular franchises in a fun and approachable way.
Kumamine’s Unique Art Style Wins Over Fans
Illustrator Kumamine is widely known for creating adorable character designs that balance humor, warmth, and expressiveness.
For this collaboration, the artist transformed several Jujutsu Kaisen characters into cute, friendly versions of themselves while incorporating bandages, tape, gauze, and first-aid supplies into the artwork.
Fans immediately recognized Kumamine’s signature style and praised how naturally the characters fit into the healthcare-themed campaign.
Many social media users commented that the artwork successfully captures each character’s personality despite the unusual setting.
Yuji Itadori Takes Center Stage
At the center of the illustration is Yuji Itadori, voiced by Junya Enoki.
Yuji is shown smiling brightly while holding a bandage, perfectly matching his energetic and caring personality.
As the protagonist of Jujutsu Kaisen, Yuji often places himself in danger to protect others, making him a fitting representative for a campaign centered around injury treatment and recovery.
His cheerful expression immediately became one of the most recognizable elements of the promotional artwork.
Choso’s “Piercing Blood” Gets a Hilarious First-Aid Twist
Perhaps the most talked-about detail in the illustration involves Choso, voiced by Daisuke Namikawa.
In the artwork, Choso appears to be using his famous Blood Manipulation technique, Piercing Blood, to create something resembling a medical pad or compress.
Fans immediately noticed the visual joke.
Social media comments included:
“Big brother is making a compress using Piercing Blood!”
“That’s the funniest use of his technique I’ve ever seen.”
The playful reinterpretation of one of the series’s most dangerous abilities became one of the illustration’s standout highlights.
Naoya Zenin Unexpectedly Becomes a First Responder
Another character drawing significant attention is Naoya Zenin, voiced by Koji Yusa.
In the illustration, Naoya appears to be rushing toward someone while carrying bandages.
The image sparked countless jokes online because Naoya is not typically known for being compassionate or helpful.
Fans humorously commented:
“Naoya is coming to treat me at top speed!”
“He’s surprisingly kind in this illustration.”
The contrast between Naoya’s personality in the story and his role in the collaboration made the visual particularly entertaining.
Other Fan-Favorite Characters Join the Campaign
The illustration also includes several other popular characters from the franchise.
Featured characters include:
- Megumi Fushiguro
- Yuta Okkotsu
- Kinji Hakari
- Hiromi Higuruma
- Panda
Each character is paired with different wound-care items, such as:
- Medical tape
- Protective pads
- Bandages
- First-aid kits
- Gauze products
The illustration cleverly matches the products to each character’s appearance and personality, encouraging fans to spend time discovering the various hidden details.
Fans Praise the Attention to Detail
One reason the collaboration has been so successful is the amount of thought that appears to have gone into each design.
Rather than simply placing characters next to products, Kumamine incorporated visual jokes and references that longtime fans immediately recognized.
Popular reactions included:
“The attention to detail is incredible.”
“Every character feels perfectly in character.”
“Kumamine’s art style makes everyone look adorable.”
“I can’t stop looking at all the little references.”
Many fans noted that the illustration rewards careful viewing, with new jokes and connections becoming apparent each time they revisit the image.

A Collaboration Fans Didn’t Know They Needed
At first glance, a partnership between Jujutsu Kaisen and wound-treatment products may seem unexpected.

Combined with Kumamine’s charming illustrations and numerous character-specific references, the campaign has already become one of the most memorable anime collaborations of the year.
As the June 16 launch approaches, fans are eagerly awaiting the full campaign and the opportunity to collect exclusive merchandise featuring these delightful new illustrations.
For many Jujutsu Kaisen fans, the collaboration perfectly balances humor, creativity, and character appeal—proving that even first-aid products can become exciting when paired with the right anime franchise.
