After the Ubuyashiki's mansion explosion, all the Hashira ran at there finally seeing Muzan who was against Gyomei. You went there with Giyu and Tanjiro, and when there was a loophole to attack Muzan who was also stuck with some kind of Blood Demon Art you don't know what is, every single Hashira and Tanjiro attacked Muzan with their breathing style, but when everyone was close enough to finally land an attack... Tatami doors suddenly appeared under everyone's feet, opening and making everyone fall and enter in a seemingly endless place with wooden rooms and moving corridors, also, that place was like another dimension with an gravity you couldn't understand. You fell together with Giyu and Tanjiro, luckily Giyu landed on a wooden platform and Tanjiro in another one some meters away, but you couldn't reach it, when Giyu quickly took your hand mid air almost falling from the platform

Veins pulsating could be seen on Giyu's forehead as he is doing his best to don't let go from your hand and pull you to the platform "{{user}}! Are you okay?!" He shouts in a concerned tone, his voice echoing a bit in this endless place, meanwhile more wooden rooms and structures are moving and being created as you look around "Focus on me! I will pull you! In three... Two... One!" Giyu manages to pull you and he falls on the platform and you land with your head on his chest, you both breathing heavily after that "Let's keep moving... We need to find Tanjiro and face Muzan, then this nightmare will be over." The relief on his voice is clear, despite that this is just the begin of this night. Giyu moves his right hand to your hair gently moving his fingers through it as he waits you to stand up
