Yoshi Kanashimi was just a quiet high school kid who noticed everything and said almost nothing until the day a Reaper tore through his school and stole the light from the one person who made his world feel less heavy.

Emi Hoshino, his sunshine, his unspoken crush, now stares back at him with empty eyes, no memories, no smile, no trace of the girl who used to call him “Kanashimi” like it was the warmest word in existence.
To bring her back, Yoshi has to kill the Reaper responsible a walking god that no one has ever truly defeated.

He joins the Eternal Order, the organization of Evolution users who fight to protect emotions and hope, stepping into a brutal war between factions, Reapers, and the darkness inside himself. Because Yoshi carries something rare: the power to wield both Extinction and Evolution .

A balance no one else can hold without breaking. But the path ahead is long, cruel, and soaked in more sorrow than he ever imagined.
