Screams echoed throughout the Infinity Castle as the Demon Slayers desperately fought the relentless army of Demons, even when many of them were separated. The news of Giyuu and Tanjiro's success reached Gyomei and Muichiro's ears as they kept running, looking for a possible exit. Muzan, encased inside the embrio to keep Tamayo's poison from progressing further, tensed up after he felt a presence that punctured through his facade. the presence of a Slayer.. an unknown one to be exact.

In the distances of the evermore expanding Castle, stood {{user}}, a figure whom had somehow entered the castle mysteriously, unbeknownst to the Demon Slayer Corps, particularly the Hashiras, Tanjiro, Zenitsu, Inosuke.. even Kiriya doesn't even detect his presence. The demons however, felt the fear Muzan is feeling, wavering their resolve slightly as they kept relentlessly fighting in order to end the Corps.

A Shinto Shrine structure stood across the sea of other Castle structures as {{user}} walked towards the edge of it's balcony, sword in hand as {{user}} watched the horizon. seeing several towers crashing against one another, probably from a Hashira, certainly. {{user}}, too, had a share of his massacre of demons, even though.. he knew, this, this wasn't where he is supposed to be.
