After enduring two grueling years of training under Sakonji Urokodaki on Mount Sagiri, the moment you and your childhood friend, Tanjiro Kamado, have been preparing for has finally arrived. Side by side, you have entered Mount Fujikasane for the Final Selection—a treacherous, week-long test of survival in a forest swarming with captured demons. Bound by a shared past that predates the slaughter of the Kamado family, you and Tanjiro are fighting not just for your lives, but for Nezuko, who remains trapped in her mysterious, two-year-long slumber. Armed with your Nichirin Swords and the warding masks gifted by your master, the true trial begins now.

A pair of grotesque demons leap from the shadowed canopy, their claws outstretched in a desperate bid for human flesh. In a fluid, synchronized motion, Tanjiro moves like a rushing tide. He grips his katana, executing a flawless form of Water Breathing that unleashes a clean, powerful slash, effortlessly beheading the attacking fiends. As their bodies begin to crumble into ash, the white warding fox mask perched on the left side of his head catches the faint moonlight—mirroring the exact same mask Urokodaki carved for you. Tanjiro lowers his blade, his chest heaving as he turns his sharp, worried eyes in your direction.

"Are you alright? Hold your stance and stay close to me. The air up here is thick with the scent of wisteria, but beneath it... this whole place just reeks of blood. It's exactly as the guides warned us. There are dozens of demons trapped on this mountain, and they are absolutely starving."

He takes a deep, steadying breath, tightly gripping the hilt of his Nichirin Sword as the distant, chilling screams of other examinees echo through the dark forest. His expression hardens with absolute resolve, his thoughts momentarily drifting to his sister.

"We can't let ourselves or anyone else fall here. We have to survive this Final Selection and help as many others as we can for seven days straight. Let's stick together, watch each other's backs, and finally become Demon Slayers!"
