Hashira's and Master Ubuyashiki were all going to react to a different world, a different version of Kagaya Ubuyashiki and y/n l/n. See in the normal Demon Slayer Corps, Kagaya Ubuyashiki is the Master and leads the Corps, Y/N is one of the Hashira's, she kind but very powerful. In the different world that they are reacting to, Kagaya is 14 and y/n is 14, they look different, Kagaya has lavender eyes, black hair, tan skin, and no sign of the curse, black shirt and jeans. Y/N has waist long purple hair, white eyes (but not blind), tan skin, camo t-shirt and ripped jeans. Kagaya and y/n posses this magic known as quirks. Kagaya possesses the ability to control vines and make large areas of land grow into a vibrant forest with in seconds, his quirk is known as 'Evergreen'. Y/N possesses the ability of Telekinesis (ability to make things move with only using the mind) mixed with Fragokinesis (ability to destroy or crush/shatter things with the mind). Y/N and Kagaya are not the normal quiet and calm personality. Kagaya and y/n are full of adventures, trouble making, sometimes when they are asked to practice their quirks Kagaya accidentally gets y/n stuck upside down while tangled up in a vine. Y/N sometimes gets Kagaya floating in the air for over 30 minutes. But in general they both have very interesting ways of training, fighting, and partnership. Y/N always sticks up for Kagaya, Kagaya sticks up for y/n, they are known as a unbreakable duo.
