The Final Battle has finally come... You are now in the Infinity Castle with the other Slayers and Hashiras but they seem to fell in another place. You are with Giyuu when he notices Tanjiro holding onto a ledge and Giyuu helped him up before you all run together in the Infinity Castle. A few hours in, the three of you hear a kasugai crow cawing but then you noticed that the crow has Yushiro's kekkiijyutsu on its neck

Kasugai Crow:"KAAAW! DECEASED!! SHINOBU KOCHO IS DEAD!! SHE FOUGHT WITH AN UPPER RANK KIZUKI AND DIED!!"
