Shift Up’s official AI-generated ‘Wanna be in Love’ video for Stellar Blade: Blood Rain has triggered fan backlash, raising bigger questions about sequel marketing, authorship, and how much generative AI may shape the game.

Shift Up’s official AI clip has become Blood Rain’s first real pressure point
Shift Up released an official music video for Stellar Blade: Blood Rain on its YouTube channel, and the strongest reaction has not been to the song, the new protagonist, or the sequel’s city setting. It has been to the label attached to the upload. According to VGC, Dot Esports, Kotaku, and Inven Global, the “Wanna be in Love” video carries YouTube’s AI disclosure, with wording that says sounds or visuals were altered or fully generated. Dot Esports also reported that the video is marked “made with AI.”
That confirmation turns the promotional clip into the first major Stellar Blade sequel backlash since Blood Rain was revealed at Summer Game Fest 2026. The sequel itself still has no confirmed release date, according to VGC and Eurogamer. Inven Global described Blood Rain as a sequel to the 2024 Stellar Blade, set after the original game in a cyberpunk-inspired city, with Shift Up CEO Kim Hyung-tae serving as general director. Inven also reported that Shift Up plans to self-publish the title.
The tension is simple, and it lands hard for an action game built on visual identity, animation impact, and character presentation. Shift Up is trying to introduce Blood Rain’s new lead through music, fashion, and mood. Fans are instead freezing the frame, catching the seams, and asking whether this is a preview of how the studio intends to market, and possibly build, the next Stellar Blade.
What the ‘Wanna be in Love’ video actually shows
The official clip presents Blood Rain’s protagonist as a K-pop-style performer singing and dancing through an environment that resembles the sequel’s setting. VGC described the video as featuring Evie against a backdrop similar to Blood Rain’s world, along with AI-generated behind-the-scenes shots that include a fake production crew wearing Shift Up shirts. Eurogamer similarly reported that the video shows Evie singing into a microphone and exploring the sci-fi city glimpsed in the game’s Summer Game Fest reveal trailer, before ending with Shift Up development team members filming, chatting, eating, and high-fiving the fully AI-generated character.
The protagonist’s name is one of the small but notable points of friction in the reporting. VGC, Eurogamer, Push Square, Dot Esports, and Kotaku refer to the Blood Rain protagonist in the music video as Evie. Inven Global’s English article refers to the new protagonist as EVE or Eve and says this marks the first time EVE has appeared in musical content as a character. The sources agree on the larger point: the video is official Shift Up promotional material for Stellar Blade: Blood Rain, and it is built around the sequel’s new lead.
Several outlets also noted details that make the AI generation visible. Kotaku pointed to inconsistent facial appearances from shot to shot, AI-hallucinated text on a vending machine, and distorted book titles, including a mangled version of Marcus Aurelius’ Meditations. Push Square cited uncanny facial expressions and visual inaccuracies. VGC said the visual style is unmistakably AI-generated, even before considering YouTube’s disclosure.
Fans are not reacting like this is a harmless side experiment
The backlash has been unusually sharp because the video was not a leak, fan edit, or off-channel experiment. It was published through Shift Up’s official YouTube presence and promoted by Kim Hyung-tae on X. Dot Esports reported that Kim shared the video and invited fan reaction. Push Square likewise reported that he encouraged followers to share their thoughts.
Those thoughts quickly turned hostile in many corners of the audience. VGC reported that “Are we deadass?” appeared multiple times in the YouTube comments, while another commenter wrote, “They really thought they were cooking with this AI slop.” Eurogamer cited similar confusion from commenters, including “The CEO wasn’t kidding, huh?” and “I mean...you could have made an animated loop with her actual model, you own the game and its assets after all…”.
The criticism also came from close followers of Shift Up rather than only from general anti-AI spectators. Push Square reported that a major fan account asked, “Where’s the artistry from a company founded and run by artists?” and added, “I can’t help but feel profoundly disappointed.” Dot Esports cited the same fan account describing the video as a showcase of Shift Up A.I. Labs that came across as “uninspiring, generic” and synthetic. Kotaku quoted fans saying Shift Up should stop using generative AI to promote Stellar Blade, with one warning that backlash could damage the IP.
The response was not unanimous. VGC reported that some viewers enjoyed the clip, with one saying, “Yeah… I’m in love…,” while another said the video was funny and they were not angry. Dot Esports noted that some fans still saw the song itself and Evie’s design as highlights. Still, the dominant story across VGC, Push Square, Eurogamer, Kotaku, Dot Esports, and Inven Global is that an official AI generated game trailer-style music video has made part of the fanbase more anxious about Blood Rain than excited for it.
The controversy lands because Shift Up has already signaled interest in AI
The Stellar Blade AI controversy is larger than one music video because the studio’s public posture around generative AI did not begin with “Wanna be in Love.” Eurogamer reported earlier this year that Shift Up’s CEO and Stellar Blade director went “all in” on AI, saying the technology was essential for competing with large rivals such as China. Dot Esports reported that Shift Up was upfront about the AI usage in the video, while Inven Global said Kim Hyung-tae has frequently expressed positive views on AI.
Push Square went further, reporting that Shift Up appears to be “all-in” on generative AI and linking the concern to previous allegations that Blood Rain’s reveal trailer contained generative AI assets. That point should be kept in its proper lane. Push Square describes the reveal trailer issue as alleged, and the provided sources do not establish exactly which assets in the game itself are AI-generated, or whether generative AI is part of Blood Rain’s development pipeline beyond promotional material.
That uncertainty is exactly the problem for Shift Up. The confirmed fact is that the official music video uses AI-disclosed material. The open question is how much Shift Up generative AI work will touch the final game, whether in concepting, background assets, marketing, character material, or production shortcuts. Eurogamer states plainly that it is unknown to what extent generative AI will be featured in the actual game. Until Shift Up explains its production process more specifically, fans are filling the silence with the most visible evidence in front of them.
Blood Rain’s marketing has a rhythm problem now
Stellar Blade earned attention through the kind of action-game language players can read instantly: the cut of a dodge, the weight of a slash, the clarity of a boss wind-up, the silhouette of a lead character framed against hostile architecture. Blood Rain’s reveal trailer, according to Inven Global, showed a new protagonist in a cyberpunk-inspired city with melee-focused combat. Eurogamer described the city as the same sci-fi environment glimpsed again in the music video. Push Square said Blood Rain’s visual identity captures the urban flavor of cities like Chongqing and Hong Kong’s dense residential architecture.
That makes the AI music video feel mismatched to the sequel’s strongest sell. An action game’s marketing depends on trust in motion. If a character’s face shifts between shots, if background text breaks apart, if a fake behind-the-scenes crew appears inside an official promotional clip, the audience starts looking at production rather than performance. The clip may have been meant as a playful character theme, but the conversation has shifted from Evie’s personality to whether Shift Up is willing to place generative AI artifacts in front of the public and call the result official.
Inven Global framed the video as a possible sign that Shift Up may use the new protagonist for wider promotional activities. That makes sense for a studio introducing a sequel lead. Character songs, idol-style presentation, and cross-media trailers can all work when they sharpen a game’s identity. Here, the first post-reveal character-forward push has created a different association: Stellar Blade 2 AI music video backlash before Shift Up has announced a date, price, platform lineup, or a detailed gameplay presentation.
The K-pop Demon Hunters detail adds another layer of confusion
One of the strangest reported details is a keychain shown in the video. VGC reported that Evie holds up a keychain reading “K-Pop Demon Hunters,” featuring Derpy the Tiger from the same series, and noted that K-Pop Demon Hunters is not associated with Stellar Blade or Shift Up. Inven Global also reported that the video includes Korean cultural elements such as EVE eating Buldak Ramen and purchasing a K-Pop Demon Hunters keychain.
The sources do not explain why that item appears in the official clip. VGC specifically says it is unclear why it is featured so prominently. Because the provided reporting does not establish a licensing arrangement, a collaboration, or a deliberate parody, the safest reading is that this is an unanswered production and approval question rather than a confirmed crossover.
That matters for the broader AI debate because generative tools are often criticized for muddying authorship, provenance, and visual control. In a game trailer, every prop usually communicates something: faction, worldbuilding, tone, timeline, joke, brand deal, or character taste. When an unexplained third-party cultural reference appears inside an AI-disclosed official video, fans are left guessing whether it was intentional art direction, a prompt artifact, an approved gag, or something else entirely. Shift Up has not provided a specific explanation for the video’s production process, according to Inven Global.
What is confirmed, what remains unknown, and whether players should wait
For now, the confirmed picture is limited but significant. Shift Up released an official “Wanna be in Love” music video for Stellar Blade: Blood Rain. Multiple outlets report that the YouTube upload discloses AI usage, with the label saying sounds or visuals were altered or fully generated. The video promotes the sequel’s new protagonist, uses the sequel’s city aesthetic, and has drawn heavy criticism from fans, including established Stellar Blade and Shift Up followers.
The unconfirmed part is equally important. There is no confirmed Blood Rain release date in the provided sources. Eurogamer reports that earlier estimates placed launch before 2027, but also says Shift Up has not given official word and that a release next year is only looking more likely, not confirmed. The sources also do not confirm final platforms, price, performance targets, editions, or whether the sequel itself will contain generative AI-created assets. VGC separately reports that the original Stellar Blade is coming to Nintendo Switch 2 later this year, but that is not the same as a confirmed Switch 2 plan for Blood Rain.
For players, the practical guidance is to treat the music video as a warning sign about Shift Up’s communication rather than proof of the final game’s quality. Blood Rain’s combat, level flow, boss design, and technical finish still need to be shown in detail. If you are excited by the sequel’s urban setting and melee focus, the Summer Game Fest reveal remains the stronger piece of game-facing material cited by the sources. If generative AI use is a dealbreaker for you, wait for Shift Up to clarify how the technology is being used in Blood Rain itself before wishlisting, preordering, or buying into sequel marketing.
The burden now sits with Shift Up. A studio known for striking character art and polished audiovisual presentation has chosen to put an AI-disclosed music video at the front of Blood Rain’s post-reveal campaign. The next trailer has to do more than look cool. It has to restore confidence that the sequel’s style, motion, and world are being authored with the care players expected after Stellar Blade.
