Mélusinen-buna

[Hatsune Miku] Meru [Original] Hatsune Miku – Meru

As n-buna himself described it as a “lantern-floating song,” when you listen, countless softly drifting lights rise up in your mind like an image.

The beautiful lyrics and the melody that touches the heart are part of it, of course, but above all it must be Miku’s delicate, fleeting voice that brings it to life.

Your ShapeKasamura Tōta

Your Shape / feat. Nayuka

This song, where Nayuka’s voice gently nestles close to your heart, is a ballad released by Tota Kasamura in September 2025.

The story unfolds as we realize that the presence of someone precious, etched deep within the hollow of our chest, is life itself.

Precisely because it’s arranged with only piano and vocals, the emotions embedded in the lyrics are conveyed directly.

It’s a track I want you to listen to when you’re feeling the pain of losing someone, yet finding the resolve to keep living.

Don’t go.Souta

Uta-nee Yuki “Don’t Go” (remaster)

As the title suggests, it’s a song about “me” reluctant to part.

Though I really want to hold you back, I swallow the words “please don’t go,” and try to hold back my tears—a touching determination that makes me feel lonely, too.

It is included on the album “Shonen Shoujo no Kotoba.”

It’s a highly addictive rock track where sweetness and pain intertwine.

KAF’s emotional vocals brilliantly capture the feelings of a protagonist seeking love while carrying trauma.

The worldbuilding, swaying between conflicting emotions, is quintessential Naisho no Pierce.

It’s a must-listen for anyone grappling with the complex feeling that “the more you love, the more it hurts.”
