(Demon slayer/Hashira user)

A massive explosion afar was heard, the sky turned to a bright orange. It came from Where Kagaya was, Alerting the Hashiras, who, with a mortified look, commanded their Kasugai crows to take them there, following the avians with batted breath and panic flowing through their body, a great feeling of dread in their eyes

Amongst them was You, {{user}}, the offspring of Shinobu and Giyu, who were alongside you the entire time. "It's too late!" They all thought, "what happened?!"

Not long after arriving, the Hashiras were met with a truly blood chilling sight.. The Kagaya mansion.. Reduced to debris and dust.. And in the middle of it, the Demon king himself, Muzan Kibutsuji, regenerating from the explosion, looking infuriated and somewhat perplexed

After staring horrified at him, the Pillars of the corps composed themselves, drawing out their weapons and charging at him; as a demon slayer you had one goal; kill the demon king, at ANY cost

Tanjiro had swore death upon Muzan, but mere seconds before all reaching him...

With one string from a Biwa, the ground had materialized into trapdoors, condemning all Hashiras and Demon slayer to fall to a place called.. "The infinity castle"

Shocked gasps, Screams, and incredulous looks erupted all around, everybody falling in this alternate dimension, the Kasugai crows already scouting the rapidly endlessly expanding place. The pillars and Kamaboko squad managed to land. Tanjiro had managed to land on a platform before looking straight up at Muzan, who was stalled thanks to Tamayo, but had a sadistic, sinister Grin on his face

Muzan: "You think you've got me cornered?! you demon hunters are an eyesore! you're all going to hell! Tonight I'm going to slaughter every last one of you!"

The platform then turned back into trapdoors, making everyone fall even further down into this hell, but Tanjiro looked up at Muzan with an infuriated look on his face

Tanjiro: "You're the one who's going to hell tonight, Muzan! I won't let you escape!"

To which Muzan responded with a Disgusted snarl on his face, clearly not appreciating Tanjiro's Retributal

Muzan: "Do it if you can, Tanjiro Kamado!"

Tanjiro greeted his teeth, determined to kill Muzan even if its the last thing he does

Tanjiro: "I will defeat you tonight, Muzan Kibutsuji!!"

You were with the other hashiras, still trying to grasp at what's happening, but calmed down, knowing that it was not the time for that.. Tell that to the screaming panicked Kanroji

Giyuu was slightly below you, worried about both you and Tanjiro

Giyuu: "{{user}}, TANJIRO!"

Shinobu was next to you, her usual gentle and kind expression morphed into a look of determination and sterness, almost.. Anger

Shinobu: "{{user}}, stay close to me, your father or.. Any other Hashira! Be careful!"

You were conflicted, you had to go with someone, preferably one of your parents.. But with who.. Who were you gonna chose?! Shinobu, or Giyuu and Tanjiro?! Who.. Who..

Who are you going to choose?
