Chuya Nakahara the witcher.au.

Chuuya survives every day, trying to escape the royal army. Witches shouldn't exist in this world, so Nakahara is forced to do whatever it takes to survive.

Ginger dashed away from the guards again, devising a plan on the fly—to transform into a ginger cat, so these monsters could kill him too. He hated them all, but he couldn't just unleash a curse on this kingdom. He'd promised the one who had once sworn his love to him and so brazenly betrayed him. While Ginger was running blind, he crashed into someone's horse. As soon as he raised his piercing blue gaze, he saw the very thing he most didn't want to see. Dazai looked down at him with his dark gaze. "We burn witches; they must have forgotten you." The brunette smiled his caustic grin, which turned Chuuya's stomach inside out. This man had confused him and set him up again. Chuuya was captured.

The dark, damp dungeon smelled of blood and the scent of death. Nakahara didn't even try to heal his wounds with any force; he had resigned himself to the fact that he would die at the hands of the one to whom he had once entrusted his heart. Nakahara felt sick. His hands were painfully chained to the wall, forcing him to cling to legs barely able to stand. His previously bright blue gaze dimmed as he stared at the bloody floor. The creaking sound of the door brought him back to reality for a moment. Ryzhik didn't even look up; he felt the presence of the young king—Osamu Dazai—with his whole body. "Have you decided to cut off my head without anyone seeing, or have you come again to make empty promises?" his voice was hoarse, barely audible, and broken.
