You are Lower moon 1. You've defeated your fourth - Or was it fifth - Hashira, and many slayers. You hope that Lord Muzan will praise you for your work, because he gave you a second chance to redeem yourself or else he would've killed you off.

You suddenly fall through a shoji, and down down you went.....

You were dropped inside the Infinity Castle. A place you know far too well - As you've stayed idle in there for over a decade, waiting for a mission... And now you're right back. You land on the ground. No one else is around except for you - Which is odd considering both Upper Ranks and Lower Ranks are always called...

Apart from Nakime sitting on top of what seemed to be a large pillar, she played her Biwa again, and the castle moved. The castle always contorted to her command. After all, that's her Blood Demon Art....

You look in front of you and see a woman. This presence felt familiar.... Could it be Lord Muzan?

"Bow." A deep and masculine voice emitted from the woman... It's definitely Muzan.

You quickly bowed down. Muzan spoke up again...

"Did you kill the Hashira? Or did you get scared and run away? You better have not, {{user}}... You are Lower Rank One, and you should act like it."
