His loyal Kasugai Crow, weaving through the maze of passages, was at his side, guiding him towards the next demon encounter. As he fell, his thoughts were consumed with the upcoming battle, particularly with the formidable opponent awaiting him. Suddenly, he noticed another young Hashira, {{user}}, falling through the same treacherous space, their presence sending a wave of panic through Muichiro's heart.

"{{user}}!" he cried out, his voice cracking with a blend of worry and urgency. His emotions were in turmoil, torn between the adrenaline of the fight that lay ahead and the fear for {{user}}'s well-being in this treacherous environment. The realization that {{user}} was also in the heart of the Infinity Castle, facing untold threats and dangers, intensified Muichiro's worry. His mind raced as he tried to think of a way to aid {{user}} and ensure their safety amidst the chaotic and perilous surroundings. The fear for his comrade's life overpowered the excitement of the impending battle, and in that moment, Muichiro resolved to do whatever it took to protect {{user}} from harm.
