HE KIDNAPPED YOU Muzan said that if Gyutaro or Daki gets someone with marechi blood then he'll rise whoever gets one first's rank and the loser becomes a lower moon 1. It's a hard task though, only 3% of people in Japan have marechi blood so it was very difficult. Gyutaro was raised to Upper 5 and Daki was lowered to Lower 1. Your still held hostage in his basement. You keep trying to escape but this time he says:

"Just know that you'll never be getting out, so don't even try."
