Imagination Forestjin

Jin / Imaginary Forest (IA) [OFFICIAL MUSIC VIDEO]
Imagination Forestjin

This is a work by Jin, also known as Shizen no Teki-P, whose Kagerou Project series sparked widespread attention through its multimedia expansion, and it was released in 2012.

It’s a refreshing song that unfolds a boy-meets-girl story.

Just listening to it, you might not think it goes that high, but especially in the latter half of the chorus, some quite challenging high notes appear.

If you sing it at karaoke, using falsetto might be a good idea.

By the way, there are arrangement variants titled “Mousou Forest” and “Kuusou Forest,” so enjoy those together as well.

Rinri’s song “Sorage-to” is a piece that resonates with anyone carrying the pain of heartbreak.

Carried by the crystalline voice of Narumaki Hime, it weaves feelings of bittersweet sorrow that many have felt at least once.

Overflowing with longing for someone precious you can no longer meet, it gently embraces the listener’s heart.

Its gently flowing melody is sure to give you the courage to move toward a new beginning.

Why not soothe the sorrow of heartbreak with this heartwarming song by rinri?

Each Time / Hatsune Miku・Kasane Teto
each timedai baku ha shin

I’m overwhelmed by the relentless onrush of sound.

It’s a track by Vocaloid producer Dammaku Hashin, released in August 2025.

The song brilliantly conveys inner conflicts—feelings of alienation within society and questions about justice—through the voices of Hatsune Miku and Kasane Teto.

The progression toward a positive message of “becoming someone who is no one” is absolutely irresistible.

When I feel like I’m losing my sense of self, this song gives me a push forward.

I’m flyyying in the skyshizensui

Flying in the Sky / Shizen-sui feat. Kaai Yuki
I'm flyyying in the skyshizensui

Your ears are captured by Yuki Kaaai’s husky singing voice.

“Sora o Tonderu” by Shizen Suisan was released in February 2025.

The subtly wavering pitch and unstable sound arrangement are striking.

Combined with the unsettling lyrical world, it becomes addictive.

Even while thinking, “This is scary,” you can’t stop listening.

If you’re looking for music unlike anything you’ve heard before, give it a try.

Just like that, just like that—stay just like that forever.kikuo

Kikuo – Just like that, just like that, just like that forever, just like that
Just like that, just like that—stay just like that forever.kikuo

It’s a song with an eerie atmosphere and profound meaning.

It fully showcases Kikuo’s unique worldview and was released in August 2023.

It expresses the desire to escape the pressures of everyday life, clearly conveying the protagonist’s longing for rest.

I think those who feel tired or suffocated by daily life will relate.

Somehow like a nursery rhyme, yet somehow mad—be sure to add this track to your playlist.

Is there life there?DIVELA

Is there life there? / DIVELA feat. Hatsune Miku
Is there life there?DIVELA

A message song centered on Hatsune Miku that really hits you in the heart.

It’s a track by the Vocaloid producer DIVELA—who has created hits like “Vocalo Coliseum”—released in 2019.

With its mixture-rock sound that unfolds a grand worldview, it’s moving enough on that alone.

And the lyrics, written from Miku’s perspective, pierce you whether you want them to or not.

By the time it ends, you might find tears naturally streaming down your cheeks.

It’s one of Vocaloid’s masterpieces, and I especially want Vocaloid producers to hear it.

Shared umbrella (used by couples); literally “mutual love umbrella,” symbolizing a romantic relationshipnatsume chiaki

This is Chifuyu Hanakuma’s version of the work originally provided to the singer Shiho.

The song, titled “Sōai-gasa” (Mutual Love Umbrella) rather than the usual “Aiai-gasa” (Shared Umbrella), portrays in a pop style the fragile relationship of two people who can only be together while it’s raining.

Once the rain stops, their bond may vanish… That tender image of leaning close to someone while holding a painful premonition tightens the heart.

Anyone who has ever carried feelings they couldn’t put into words will surely relate.
