Crossover: I Don't Want Your Demon Power, Thanks

Shan Yu transmigrates with a System. By helping monsters or earning their gratitude, he can gain their abilities. These abilities are powerful enough to keep him safe in Heian-kyo, a city teeming with spirits and monsters. But he discovers a bug in the System. Having the same demonic power as other monsters is troublesome enough, and now it can even change his outfit in an instant, making him dress just like that monster??? Shan Yu feels his rabbit ears, kicks Shuten off the bed once again, and refuses his demonic power, refusing to expose his chest again. Shuten smacks his lips and says fine. That night, after getting Shan Yu drunk, he tries a Yamausagi outfit roleplay scene. Theme: Salvation
