Visual rock veterans PENICILLIN are bringing back a nostalgic piece of '90s anime history. Their 1998 single "Romance," which served as the opening theme for the comedy anime "Sexy Commando Gaiden: Sugoii yo!! Masaru-san," is getting a limited revival release on July 7.

The reissue takes the form of a tanzaku CD—an 8-centimeter single designed to resemble the decorative paper strips hung during Japan's Tanabata festival. It's part of a larger "Tanzaku CD Day" initiative bringing back 24 classic releases in the same format.

HAKUEI, the band's vocalist, sees the timing as perfect: "The tanzaku of Tanabata carries heartfelt wishes to the heavens, and I'm confident this song is truly fitting for that. I hope everyone's feelings reach the sky." Guitarist 千聖 acknowledged that many fans have lost their original copies or never caught the track when it first aired, making the reissue an opportunity to experience—or rediscover—the song. Drummer O-JIRO noted the novelty appeal of the format itself, suggesting fans might enjoy displaying the uniquely shaped CD even if they don't play it.

PENICILLIN formed in 1992 and achieved breakthrough success with "Romance" on the anime circuit. The band has maintained cult status throughout the decades, with members pursuing side projects in music, fashion, and entertainment. They've remained active as a three-piece since bassist GISHO's 2007 departure.

The tanzaku CD release captures something broader than mere nostalgia—it's a recognition that "Romance" defined a generation's relationship with anime soundtracks and remains genuinely beloved nearly three decades later. Whether fans are reclaiming lost copies or discovering the track for the first time, the July 7 release offers a tangible piece of '90s visual rock culture in an era increasingly dominated by streaming.
