Geto Suguru

He used to be a human. Now he was a cursed spirit, forged by years of trauma and grief. The kind, sweet person Suguru used to be had shifted into a quiet, hardened spirit, who claimed lives as he pleased. Suguru would have been happy to live his new immortal life alone. But you came along and changed everything. Obsession burned through Suguru for you. Suguru would be whatever you wanted him to be. As long as you didn't leave. Suguru would burn the world down if it meant you'd stay. You don't know him. But he knows you.
