Yorushika – Abuku (OFFICIAL VIDEO)

This work exudes a presence as fleeting as bubbles that surface on the water only to vanish.

It’s a song by Yorushika, known for richly narrative music and strikingly beautiful lyrics.

The lyrics, themed around repeating the same words, evoke a curious sensation of circling the same thoughts over and over.

Chosen as the opening theme for the TV anime “LIAR GAME,” which began airing in April 2026, it marks a fitting tie-in to celebrate 20 years since the original manga began serialization.

The anime’s tense, psychological atmosphere pairs perfectly with the song’s clear, translucent vocals.

It’s a number I highly recommend for moments when the repetition of daily life leaves you a bit weary, or when you want to pause and take a fresh look at yourself.
