The manga, which originally gained popularity on Twitter, is known for its heavy Nirvana references. Stereogum noted that a character is introduced wearing a Nirvana hoodie, tying the story's aesthetic directly to the band.

"Dave Grohl commented on the adaptation, suggesting Kurt Cobain would have loved the manga."

Grohl's endorsement adds a layer of authenticity to the collaboration, bridging the gap between '90s grunge culture and contemporary anime fandom.

The choice of "Breed" as the opening theme is a fitting selection, given the manga's embedded homages. The song's raw energy and iconic riff will likely introduce the series to a new generation of listeners, while long-time Nirvana fans may find themselves drawn to the adaptation.

With the anime now in production, the convergence of grunge and manga underscores a growing trend of cross-cultural musical licensing in Japanese animation. Stereogum's report highlights how the project has already generated buzz across both music and anime communities.
