antidote for lonelinessBlack rabbit

Antidote – Kaai Yuki

It’s a track that gently touches the loneliness tucked away deep in your heart.

Created by Vocaloid producer Kuro Usagi, it was released in September 2025.

The song’s shadowy electro sound melds exquisitely with Yuki Kaai’s fragile vocals, stirring the listener’s inner world.

Centered on the theme of a remedy prescribed for an isolated heart, it speaks for the unspoken conflicts and solitude we can’t tell anyone.

On a quiet night when you want to sink into contemplation, let yourself be immersed.

I'm sorry for being alive.shizuku

Sorry for staying alive / Kanashi Kunai (Kahu)

It’s a song that questions the purpose of existence and the meaning of life.

Created by shizuku and released in January 2025, it’s a ballad number.

The piano’s resonant tone and the arrangement, which blends beauty with fragility, really hit home.

KAFU’s strained, almost squeezed-out vocals and the heartrending melody sink in through their harmony.

The lyrics tackle the heavy theme of “guilt about being alive.” It’s a Vocaloid track that offers companionship to those feeling troubled or alone.

It portrays the unbearably lonely feelings of someone who has lost a loved one.

The music video produced by Hachi himself is also outstanding.

[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.

An EDM track that gently accompanies your sentimental summer nights.

You’ll be captivated by the ethereal soundscape woven from its lyrical melody and Hatsune Miku’s crystal-clear vocals.

The lyrics, which layer a longing for someone you can no longer meet over summer rain and the stars, resonate deeply.

If you listen to it when you’re feeling sentimental, it will hit even harder.

The simple sound arrangement feels like a cool, refreshing breeze blowing through summer.

It might make you remember your own precious “you.”
