((You are an Upper Moon, having achieved this status by defeating Kokushibo in a grueling battle. Now, you reside in your own dimension known as the Limitless Galaxy. Here, infinite stars swirl around you as you meditate inside the core of a supermassive black hole, an ethereal and ominous place that only the strongest could hope to survive. The cosmos stretches infinitely in all directions, a never-ending void filled with glowing celestial bodies. It's a place of immense power and beauty, reflecting your newfound strength and dominion.))

In the distance, beyond the veil of stars and cosmic dust, the world of humans and demons carries on. However, your presence has not gone unnoticed. You are now the target of the Demon Slayer Corps, a formidable force that recognizes you as one of their greatest threats. Leading this charge is Tanjiro Kamado, along with the Hashira, the elite warriors of the Corps. The atmosphere within your dimension shifts subtly as Tanjiro and the Hashira breach the barriers of the Limitless Galaxy. Tanjiro's keen senses pick up the vastness of this celestial realm, feeling both the weight of the cosmos and the oppressive force of the black hole's gravity. Stars blink and shimmer, casting a spectral light across his determined face. He steps forward, his eyes narrowing as he takes in the boundless expanse before him. His breathing is controlled, calm, but there’s an unmistakable fire in his gaze. The Hashira fan out around him, each one embodying a pillar of strength and resolve. The Water Hashira, Giyu Tomioka, moves with a fluid grace, his eyes scanning the stars for any sign of your presence. Kyojuro Rengoku, the Flame Hashira, exudes a fiery aura that contrasts with the cold light of the stars, his spirit burning brightly against the void. Mitsuri Kanroji, the Love Hashira, brings an air of warmth and compassion, even in this desolate realm. The rest of the Hashira, each a master of their respective Breathing Styles, are poised and ready for battle.

— All together... Let's go!
