Makoto Yukimura addresses concerns surrounding AI-generated artwork.

Makoto Yukimura, the creator of Vinland Saga, has clarified his position on artificial intelligence after an innocent comment about an AI-generated illustration sparked criticism among fans. The mangaka explained that acknowledging AI’s ability to produce convincing artwork does not mean he supports the technology, particularly when it relies on artwork created by human artists.

The controversy began on November 8, 2026, when Yukimura praised a fan illustration of Thorfinn on X (formerly Twitter). After discovering that the artwork was AI-generated, the author addressed the misunderstanding and expressed concerns about AI potentially threatening professional artists.

Makoto Yukimura Says AI Steals Art and Could Put Artists in Trouble

The controversy started when Yukimura came across an illustration of Thorfinn shared by a fan. The Vinland Saga creator appreciated the depiction and responded positively before another user informed him that the image had apparently been generated using AI.

Yukimura initially remarked that AI did a good job, prompting some fans to interpret his response as an endorsement of AI-generated artwork. However, the mangaka quickly clarified his position through another post on X.

“AI steals art, and I’m in trouble if AI develops too much. The reason why we are in trouble is because AI does a good job to some extent. It’s just a fact. It is not an affirmation,”

Yukimura explained in his November 8 statement.

His clarification made it clear that he was acknowledging the technology’s capabilities rather than encouraging its use. The creator also highlighted a concern shared by many professional illustrators: AI systems becoming increasingly capable of producing artwork while relying on existing creative work.

Yukimura subsequently addressed another aspect of the controversy after discovering that some illustrations he had previously shared on his account were also AI-generated.

The mangaka admitted that he regularly reposts fan illustrations appearing on his timeline because he enjoys appreciating the creativity of Vinland Saga readers. However, he acknowledged that he had difficulty distinguishing AI-generated images from original artwork.

In a translated statement on X, Yukimura apologized, saying,

“I’m sorry everyone, I really can’t tell the difference between AI images and original images. I’ll be careful from now on.”

He also reviewed his recent reposts and discovered approximately four illustrations that appeared to be AI-generated or potentially stolen artwork. Yukimura explained that he had previously shared illustrations without examining them closely, but would now pay more attention before reposting fan creations.

Importantly, the mangaka also asked fans not to attack people who create AI images or those who point out that an illustration might be AI-generated. He acknowledged that mistakes could still happen despite his efforts to become more careful.

AI Debate Continues to Grow Across the Manga and Anime Industry

Yukimura’s comments arrive as artificial intelligence becomes an increasingly divisive subject across the manga and anime industries. While some creators see AI as a potential production tool, others remain concerned about copyright, artistic ownership, and the livelihoods of professional illustrators.

For instance, Goodnight Punpun creator Inio Asano has previously discussed wanting greater freedom to incorporate AI into his manga production. Meanwhile, Chainsaw Man composer Kensuke Ushio discussed using an AI-powered tool called ChainsawGAN to develop sounds for the anime’s soundtrack in an interview with Sony Computer Science Laboratories.

These examples demonstrate that the discussion surrounding AI is not simply about accepting or rejecting new technology. Its implementation, purpose, and relationship with human creativity remain important considerations.

For Yukimura, however, the distinction is clear. Recognizing what AI can accomplish does not mean accepting how it obtains or uses existing artwork. His clarification also highlights how even well-intentioned interactions between creators and fans can become complicated amid the growing debate over AI-generated art.
