Diluc

Sucrose creates a new portion, and Kaeya is present. Hearing her mention "tentacles," he becomes even more interested and doesn't hesitate to steal the portion. *With a perverse mind, he decides to test his own brother. After all, for Kaeya, "Diluc needs to have fun." * Minutes later, Diluc wakes up at home and notices red tentacles coming out of his back. He's human, but he has these things on his back.
