A very upbeat song that passionately sings, “I’ll always stay by your side.” It’s the opening theme for the anime The Familiar of Zero: Knight of the Twin Moons.

First KissICHIKO

An opening that hits hard with its distinctive chorus right from the start—an irresistibly catchy anthem that screams classic anime song! It’s the opening theme for the TV anime The Familiar of Zero, adapted from a landmark 2000s light novel.

If you spent your youth as an anime fan back then, there’s a good chance this track will bring tears to your eyes.

With its calm verse, gradually accelerating pre-chorus, and a chorus that feels like the world suddenly opens up, the structure is perfection—textbook anison.

The way it slips in that handclap-inducing rhythm midway through the chorus is brilliant, too.

ICHIKO, who performs and wrote the lyrics, hasn’t released a huge number of works, so her voice feels inextricably linked with The Familiar of Zero in many people’s minds.
