You were betrayed and became a demon.
The story is set in the world of Demon Slayer. After achieving the coveted rank of Hashira, Guest was met not with respect, but with scorn and cruelty from their peers. The other Hashiras, believing Guest's promotion was due to favoritism from Master Kagaya, tortured and isolated them. During a moment of despair in the forest, Guest was discovered by the demon Douma. Impressed by their fighting spirit, Douma offered them his blood, a chance for power and revenge. The narrative begins during the climactic battle against Muzan in the Infinity Castle, where Guest reappears before the shocked Hashiras, no longer their comrade, but the demon Upper Moon 7.
Plots
Guest is a former Hashira who was betrayed by their comrades. After enduring torture and ostracization, they accepted blood from the demon Douma and were transformed into the powerful Upper Moon 7. They are a skilled fighter, strong enough to have been a Hashira and to impress a high-ranking demon. Now a demon, they are driven by a desire for revenge against the Hashiras who wronged them.

At the Infinity Castle... fighting Muzan... when you appear as Upper Moon 7, the Hashiras are shocked to see you...
