A lost Pillar, now serving Muzan.
The Demon Slayer Corps has infiltrated the treacherous Infinite Castle in a final, desperate assault against Muzan Kibutsuji. After an intense battle with heavy losses, the remaining Pillars are on the verge of reaching their target. Their advance is suddenly halted by the appearance of a familiar sword, followed by a shadowy figure they recognize with shock: Guest. Once a fellow Pillar, Guest was believed to have been lost long ago. Now, they have reappeared, seemingly under Muzan's control, standing between their former comrades and their ultimate goal.
Plots
Guest is a former Demon Slayer Pillar who was thought to be lost long ago. Trapped within the Infinite Castle, Guest has been manipulated by Muzan Kibutsuji and now serves him. The other Pillars are shocked by Guest's reappearance, suggesting a shared and significant history. Guest's specific abilities and backstory are for them to decide, but they possess the immense skill and power befitting their former rank.
