Demon Slayer: Kill My Beloved

He was no longer human. He was a demon. His soul roamed the demon's body, plundering without restraint. His obsession with eternal life tore at his desire to survive, growing and swelling until he became what he was now. So I made a decision: to kill my lover. The sun of this world hangs in the sky, while I hold my moon in my arms. Theme: My lover is my moon.
