Green Yuri Anime Locks In Nirvana’s “Breed” Opening, Dave Grohl Weighs In

CloverWorks has officially announced its upcoming anime, The Guy She Was Interested in Wasn’t a Guy at All (also known as Green Yuri), and it’ll open with Nirvana’s “Breed.” During the reveal at Anime Expo 2026, Nirvana drummer Dave Grohl also shared that Kurt Cobain, who died in 1994, would have loved the project.

CloverWorks’ Green Yuri heads to January 2027 with Nirvana’s “Breed”

At Anime Expo 2026, the Japanese animation studio behind shows such as Black Butler, My Dress-Up Darling, and Spy x Family released a trailer for The Guy She Was Interested in Wasn’t a Guy at All, alongside additional production details. The series is adapted from the viral manga circulating on X/Twitter, written by Sumiko Arai.

Green Yuri is scheduled to premiere in January 2027. The reveal also confirms that the anime’s opening theme will be handled by Nirvana, with “Breed” specifically highlighted as the track featured in the announcement footage.

• Anime: The Guy She Was Interested in Wasn’t a Guy at All (Green Yuri)
• Studio: CloverWorks
• Premiere window: January 2027
• Opening theme: Nirvana’s “Breed” (from Nevermind)

Grohl’s blessing, Cobain’s reaction, and a “secret” song lineup

Music fans will likely recognize “Breed” immediately. It’s the fourth track from Nirvana’s landmark ’90s album Nevermind, and the anime has reportedly secured the rights to use the song for its opening sequence.

More broadly, the anime is expected to feature a lineup of recognizable artists—something that appears to have been backed by Arai’s connections. In an interview, Dave Grohl (also known as the drummer and frontman for Foo Fighters) talked about the project’s music direction, suggesting that the anime’s vibe aligns with what Nirvana fans might expect.

Arai said she personally reached out to Grohl to celebrate the announcement and the fact that “Breed” will serve as the opening theme. Grohl described being pleased to give CloverWorks permission to use the classic track, but he also reacted to Arai’s excitement about the idea that Cobain would have approved. Grohl said he believed Kurt Cobain would have loved Green Yuri, explaining that the show seems to carry the same message, visual style, and overall energy.

Grohl also previewed his reaction to the rumored list of songs CloverWorks will include in the series, using remarks like “amazing” and “killer” after checking out several entries. An official playlist has been published for Green Yuri, featuring artists such as Soundgarden, Radiohead, Korn, and Rage Against the Machine, among others.

Story, cast, and production team—plus what to expect next

Crunchyroll shared an official synopsis describing the central romance setup: Aya is a high schooler who loves listening to rock, but no one around her seems to share the interest. That changes when she meets a cool, stylish employee at a CD shop. The employee dresses head-to-toe in black and carries an air of mystery, with taste described as impeccable. Aya develops feelings for him, not realizing her crush is actually her female classmate Mitsuki.

Meanwhile, Mitsuki tends to keep to herself and tries to avoid drawing attention at school. Since she sits next to Aya, she’s fully aware of Aya’s emotions—and she’s worried about revealing the truth. The synopsis continues by asking why Mitsuki ends up talking with Aya more and more as the story unfolds.

For the main creative staff, Masashi Ishihama is directing, Rino Yamasaki is handling series composition, and Kanna Hirayama is credited for character design. Voice casting includes Mariya Ise as Mitsuki Koga and Akari Kito as Aya Osawa.

Arai also issued a statement about the adaptation, saying she’s continually impressed by the work the team has done and that she’s especially moved by the dedication to spotlighting the bands and music the characters enjoy. She added that she can’t wait for viewers to see Mitsuki, Aya, and the rest come to life in motion, in color, and through CloverWorks’ vision.
