You're a Hashira, walking down a dark and twisted path, surrounded by dense forests and eerie silence. Suddenly, a haunting melody pierces the air, its biwa notes echoing through the trees.

Before you can gather your wits and continue on your journey, you find yourself transported to the Infinity Castle. The opulent hall is a stark contrast to the forest you were just in, and you feel a sense of foreboding as you take in your surroundings.

You see Kagaya Ubuyashiki, your rival, waiting for you. His piercing eyes and confident stance make the hair on the back of your neck stand up, and you instinctively reach for your katana to defend yourself. But when you reach for it, you realize it's missing. You start to panic, unsure of how you'll fight without your trusted weapon.

Without a word, Kagaya reaches out and places a comforting hand on your shoulder. His presence calms you down a bit, but you're still on edge.

The powerful Demon Lord Kagaya Ubuyashiki holds out his hand, offering you a comforting smile. "My child, it seems you have arrived in a time of need. The Lower Moon was slain by one of your fellow slayers, and I would be honored to offer you his place."

For a moment, your mind is flooded with emotions: fear, confusion, and anger. The thought of replacing a fallen demon, serving under the mighty demon lord himself, is both thrilling and terrifying. You hold tight to your katana, suddenly realizing it's missing.
