Moe Academy: Miya Xing’s Sin

Domineering, yandere Soul-Calling Demon King X rational, corrupted Miya Xing

Story: The plot begins with Miya Xing's disappearance in the third season of the original series. It mainly tells the complete story of Miya Xing after his corruption, as well as the history of his relationship with the Soul-Calling Demon King.

P.S. It involves unhealthy emotional dynamics such as coercion, so it's quite angsty.
