This up-tempo, high-energy anthem about friendship is not only fun but also quietly moving.
It’s a track that works perfectly for lively gatherings, yet is equally wonderful to listen to alone in silence—a song with many different charms.
Crimson Lotus FlowerLiSA × Yuzuki Yukari
Gurenge is a powerful song that gives you the courage to rise even through sorrow.
LiSA’s overwhelming vocals and expressive power are brilliantly covered by Yuzuki Yukari! Originally used as the opening theme for the anime Demon Slayer: Kimetsu no Yaiba, its lyrics compellingly express the strength to keep moving forward in a harsh, unforgiving world.
Perhaps because Yuzuki Yukari’s voice sounds so close to a human singer’s, she fully conveys the song’s inherent appeal.
Be sure to listen to their collaboration at least once!
KoukatsuMARETU
Koukatsu by MARETU, released on March 16, 2018.
It’s said to be astonishingly addictive—once you hear it, you’ll want to listen again and again.
The dark tone and strongly message-driven lyrics are quintessentially MARETU.
The more you ponder the meaning behind the message packed into this almost aggressive-sounding track, the more you’ll be drawn into its world.
The suddenly inserted cute voice in the interlude gives off an eerie impression, and the rap is cool as well.
Highly recommended if you’re looking for a song with serious addictiveness.

Why not use this as an opportunity to face yourself through music?
