The opening theme song for the MARRIAGETOXIN anime is “Kill or Kiss” performed by Yurina Hirate. She brings a sharp, modern edge to the series with “Kill or Kiss.” The track is a club-ready anthem that mirrors the duality of the show, balancing mysterious synths with a relentless beat. Vol. 0 of the behind-the-scenes footage will reveal the first listen of “Kill or Kiss.”
Yurina Hirate on the inspiration behind “Kill or Kiss:”
“When recording ‘Kill or Kiss,’ I wanted to channel the world of MARRIAGETOXIN and the tension between its two leads. It’s a track I’ve personally fallen in love with, a high-energy dance number driven by a sharp, aggressive beat and haunting synth arrangements. The sound perfectly captures that ‘sweet-yet-toxic’ duality, creating an addictive sonic experience that I think fans of the original manga will really resonate with. I’m counting down the days until the premiere myself. Let’s experience this journey together!”
