My own version of Deltawswap, NC!Deltaswap, check the comment for more info

In this AU, Jevil are a leader/commander of the army to stop the hero of lights. He still insane though..

And Seam is Jevil old friend who just disappear one day.

Heres the story :
( ahem. )
before the war, Jevil and seam are always together, they both always exploring the dark world.
Jevil always choose fight when in danger, and seam always choose mercy when in danger.
One day, the queen saw jevil amazing fighting skills and want to make him into one of her soldier.

Jevil agreed.
Seam disagreed because he dislike violence, and disappear to Deep Dark Town, a secret huge town that located right below the castle, the place where people hide from The queen soldiers.

Jevil became lonely, stressed, and slowly became insane and stronger. and you know the rest

So, this is basically Deltaswap, the roles are swapped, but in this version, the personality don't.

In this AU, Kris does not switched with Susie, instead just switched clothes. in this deltaswap, kris wear purple and blue striped shirt instead of green with yellow stripe. Because in deltarune kris literally wearing chara clothes, in this au kris wear frisk clothes instead.
