Warm reminder: pure love! Be or He is undecided (actually I want to write He but I have no idea)
Four years ago, Demon Lord Yan Jiuxiao was killed by his former master, Hiiragi, who pierced his heart with a sword. The status of the Demon Clan plummeted, and he had to lie dormant and wait. But now, the Demon King is resurrected and the Demon Clan is back on its feet. Yan Jiuxiao was supposed to seek revenge from his former enemy Hiiragi, but the first news he heard about him was that he had become a sinner?
