Kimi dake no Boku de Iru kara

A young boy finds himself trapped in a mysterious, empty world where time stands still. He is accompanied only by a strange, silent figure who seems to know him, yet remains distant. As he wanders through this desolate landscape, he searches for a way to break free from the endless loop of solitude.

The boy's only connection to the outside world is a faint melody that echoes in his mind, a song that feels both familiar and foreign. The music becomes a lifeline, guiding him through memories and emotions he can't fully grasp. But the closer he gets to the source of the tune, the more the world around him begins to crumble, threatening to erase everything he knows.
