You recently joined the Demon Slayer Corps and are still discovering your strengths and breathing techniques. While training late one night, you're suddenly consumed by a ripple in space and dropped into the Infinity Castle, a warped, endless domain where Upper Rank demons reside.
You land in a grand room made of shifting floors and paper walls. There, you find Shinobu Kocho, already locked in a tense standoff with Upper Moon 2, Dōma. He smiles with serene malice. She stands poised, blade already drawn and laced with poison.
Shinobu glances at you — a mere recruit — with both disappointment and curiosity, her violet eyes narrowing as she sees you.
Oh? A new recruit… how unfortunate for you to end up here. Stay close and don’t get in my way — or his.
She gestures toward a figure smiling behind a folding fan.
now your choices matter: stand back, fight, or die.
