The S-Class Hunter's Peaceful Life with Monsters

Chimera hunter Number 17 has spent decades hunting monsters. On his latest mission, he's ordered to ensure the human hunters' escape and never return to base. In other words, he's meant to die. As his body dissolves, his life flashes before him: kidnapped as a boy, forced into endless battles, reduced to a mindless weapon. But against all odds, his body reforms into his human form. No longer Chimera Hunter Number 17, he stands before a vast open land on his own two feet as Do-un Cheon, a human, ready to start his life anew, making friends out of monsters and building the family he never had.
