Keina Suda Is Done Being Gentle — ‘Nightmare’ Is the Sound of an Artist Letting Go of Everything Safe
Love turning into hate. Kindness becoming a wound. Pain becoming comfort. If you were expecting the artist who gave the world “Charles” to come back soft, Keina Suda just made it very clear — that version of him is gone.
“悪夢 Nightmare,” the new single from the singer-songwriter also known as Vocaloid producer Balloon, is not a gentle return. It is a deliberate rupture — a ballad that begins with a delicate melody and then builds, slowly and inevitably, into something far more consuming. It is also the first window into “LOVE HATE,” his upcoming major third album and his first full-length record in approximately three years. And if this song is any indication of where that album is headed, Keina Suda is operating at a different level entirely.
From “Charles” to “Nightmare”: An Artist Who Refuses to Stand Still
To understand why “Nightmare” hits as hard as it does, you have to understand what Keina Suda built his name on. “シャルル Charles,” his breakthrough track released under his Balloon alias, became one of the most beloved Vocaloid songs of its era — its Vocaloid and self-cover versions have combined for more than 160 million views on YouTube. It is delicate, melodic, and deeply emotional in the way that only the most quietly devastating songs can be.
“悪夢 Nightmare” is none of those things — and that is entirely the point.
The song explores the contradictions that live inside a single person: how love curdles into hatred, how an act of kindness can leave a scar, and how pain can paradoxically become the one thing that feels like relief. It starts gently enough with a fragile opening melody that lulls you in — and then the arrangement swells, the emotional stakes climb, and by the time it reaches its peak, the song has become something that demands to be felt rather than simply heard.
Keina Suda himself didn’t reach for metaphor when describing what “Nightmare” is about. He went straight to the bone.
“It’s like kindness turning into thorns. Love transforming into hatred. Finding comfort in pain. This is a song about foolish human beings.”
The music video, directed by Takumi Osera, pushes those themes even further. Built around the idea that beauty can only emerge when despair cannot be escaped, the video suspends its world somewhere between loss and acceptance — searching, visually, for what is left after everything else has been stripped away.
“LOVE HATE”: A 16-Track Album Built Around Collision
“悪夢 Nightmare” doesn’t exist in isolation. It is the opening statement of “LOVE HATE,” scheduled for release on September 9, and the architecture of that album makes the ambition clear: 16 tracks, six brand-new songs, and a tracklist that pulls together some of the most significant work of Keina Suda’s recent career — anime themes “ユートピア Utopia,” “ラストルック Last Look,” and “ラブル Rubble”; drama tie-ins “ユーエンミー You and Me” and “リベラ Libera”; fan favorites including “ミーム meme”; and a reinterpreted version of “WOLF” featuring rock band Hitorie.
The title “LOVE HATE” suggests a collision between opposing forces — and “Nightmare” sets that collision in motion immediately, locating the contradiction not between two people or two moments, but inside a single human heart. That is a more unsettling and more honest place to look, and it signals that Keina Suda is not making this album to be comfortable. He is making it to be true.
For an artist who built 160 million views on the back of one of J-pop’s most tender songs, choosing “Nightmare” as the face of his comeback is a statement. It says that the gentleness was never the whole story — and that what comes next is going to hurt in all the right ways.
“LOVE HATE” drops September 9. Consider yourself warned.
