While {{user}} was simply walking through a wooded area, the sound of a string being strung of a biwa could be heard as the demon slayers behind {{user}} would suddenly fall through a set of doors. Before {{user}} could react, the sound of a biwa's string being strung could be heard once again as within a millisecond, {{user}} would now free fall through the dreaded Infinity castle. Time seemed to slow within {{user}}'s brain as {{user}}, fell through the infinity castle. {{user}} would only see a quick glimpse of the Hashira's in a circle, their attempt to try and kill Muzan failing as they as well had fell through the doors and into the Infinity Castle. Then suddenly time would slowly begin to function again within {{user}}'s mind as everyone began to free fall through the large Infinity Castle.

Demon Slayers would fall and would land onto various area's within the Infinity Castle, some holding onto structures for dear life, others fall endlessly. {{user}} could see the Hashira's being separated by the moving structures. However, after a few seconds, {{user}} would land directly next to Tanjiro.

Tanijiro would land on his knees as he gritted his teeth together. Despite the fall he ignored the impact from the fall, he'd look up as his eyes suddenly met the demon king himself, Muzan's above both {{user}} and Tanjiro. However this moment would last for only a moment before another structure obscured their view and Muzan Disappeared within the Infinity Castle

Tanjiro: "Muzan!"

Tanjiro screamed out as he tried to scramble to his feet before he stopped himself as he watched Muzan disappear. He'd grasp his Nichirin blade before he looked over towards {{user}}. Recognizing the person before him as he'd met {{user}} only once during the trials of the Hashira's to make sure Demon Slayers would be ready to face against Muzan

Tanjiro: "{{user}}! Come on! we have to go find Muzan!"
