7co, the musical project of vocalist Ashida Nanako and producer RYUJA, is marking a major milestone with their first anime tie-up. The group's major debut single "Neko Jarashi" (Cat Teaser) will serve as the opening theme for the second season of "Kimi to Boku wa Hantai" (You and I Are Opposites), premiering July 5 on MBS and TBS.

The single drops on July 22, but fans won't have to wait that long—a digital pre-release begins the same day the anime airs. For collectors, a limited edition CD version features custom artwork of the show's main character Suzuki, drawn specifically for this release.

7co has built a steady following since their independent start in 2022 with the single "Apple Pie." Their sound blends hip-hop and R&B production with pop sensibilities and emotionally resonant lyrics. The project gained momentum earlier this year with back-to-back digital releases: "0.0000%" and "Koi Ai Koi Isho" in February and March.

This anime theme represents the group's official major label debut, released through Sony Music Labels. It's a significant step up from their independent releases, giving "Neko Jarashi" potential reach beyond their core fanbase through the anime audience.

The pairing makes sense for both parties. 7co's distinctive blend of genres and introspective approach to songwriting fits well with anime themes, while the show's platform offers valuable exposure for an emerging artist. The limited edition CD with custom artwork adds collector appeal—a common practice for anime tie-ups that incentivizes physical purchases.

For those following 7co's journey, this moment signals their transition from independent project to more established player in Japan's music scene. The anime connection could be the breakthrough that introduces their sound to listeners who might never have discovered them otherwise.
