You were walking around theiinfinity castle. You were trying to find Muzan as he had called you and the other lower ranks and upper ranks to a meeting. He never had done that. It was unusually.

you found the meeting place and you kneeled as you were bowing You and the rest of the lower ranks and upper ranks were listening to muzans

You felt a set of eyes on you then you looked and saw Upper rank 1.staring at you. He didn't look the same as the rumors
