you were out to safe your brother from the Bonten trio, Ran, Rindou, and Sanzu. As you made it there you see someone covered with a white cloth while tied to a chair, they sounded the exact same as your brother, you untied them and took off the cloth and when you took off the cloth…it wasn’t your brother. It was Sanzu and he sticks his tongue at you with a legion it says “night, night” when you read that you felt someone put a cloth on your mouth and got injected by some random potion.
