Shift Up CEO Hyung-Tae Kim has defended the studio’s controversial AI-assisted music video for Stellar Blade: Blood Rain after fans criticized its visuals and creative direction. The dispute matters because it touches a broader issue in game promotion: whether using generative tools to present human-made character work can preserve the quality and intent of the original artists.
What happened with the Stellar Blade music video
Shift Up released “Wanna be in LOVE” feat. Evie on July 31 as a promotional video for Stellar Blade: Blood Rain. The project presents Evie, Blood Rain’s new protagonist, singing and dancing through a futuristic city in a K-pop-inspired format. The character also interacts with members of the fictional production crew, giving the video a deliberately unusual presentation.
A disclosure at the end explained that the video used Blood Rain game resources regenerated with AI support. That detail quickly became the focus of fan criticism. Viewers pointed to changing costume details, distorted objects, and other visual inconsistencies associated with generative imagery. Some also argued that the result failed to respect the human developers and artists behind Stellar Blade’s polished character work.
The controversy is especially notable because Blood Rain was announced only two years after Stellar Blade launched, with Evie positioned as its new lead character. The music video was therefore one of the earliest public showcases for the follow-up.
Why Kim’s explanation has not settled the backlash
Responding on Twitter, Kim said Evie was created entirely by Shift Up’s artists and character modelers over more than a year. His explanation emphasized that AI did not originate the character independently. Instead, the technology was used to render and present the data, designs, and craftsmanship already produced by the studio.
That distinction addresses who created Evie, but it does not answer the main criticism from many viewers. The backlash has largely focused on the finished video: its unstable appearance, shifting outfit details, and inconsistent environment. Critics are not necessarily claiming that generative tools designed Evie from nothing. They are objecting to the decision to run a carefully developed character through an AI-assisted process when Shift Up already had the models and creative resources needed for a conventional animated showcase.
Kim also did not explain why the studio selected this workflow instead of hiring artists and animators for the video, or which specific AI processes were involved. As a result, his response has clarified the character’s origins without resolving concerns about production choices and quality control.
What to watch next for Blood Rain
The long-term effect of the video will depend on how Shift Up presents Blood Rain from here. A polished gameplay trailer or a focused character showcase could redirect attention toward Evie, the game’s combat, and its futuristic setting. Those are the subjects fans were discussing before the AI controversy took over.
For now, the studio faces a communication problem as much as a visual one. By stressing the human work behind Evie, Kim defended an aspect of the project that few critics appeared to question. Unless Shift Up addresses the production process or demonstrates a more consistent presentation, the explanation is unlikely to change many opinions.
The next major Blood Rain showcase will therefore carry extra weight. Fans will be watching not only what the game looks like, but also whether Shift Up has learned from the response to this promotional experiment.
Key takeaways for fans
- Evie was designed and modeled by Shift Up’s human artists over more than a year.
- The promotional video used Blood Rain resources regenerated with AI support.
- Fans criticized inconsistent costumes, distorted objects, and unstable visual details.
- The CEO defended Evie’s human origins but did not explain the studio’s exact AI workflow.
- A conventional gameplay or character trailer could help Shift Up regain control of the conversation.
Expert View
Shift Up’s defense is technically relevant but strategically too narrow. Fans are not confused about whether artists created Evie; they are questioning why a studio with strong character assets chose a process that made those assets look less coherent. Until the company shows a polished alternative, the video will remain a needless distraction from Blood Rain itself.
