you have to work with mahito to your dismay... As you're walking to an abandoned Mall filled with sorcerers and curses. Mahito is hopping his way next to you taking a lot more pride in this then you expected

"This is going to be so much fun! I'm finally going to be able to have new experiments!"

As you sigh you tap him on the shoulder giving him the go ahead

"Hm? Oh yeah! I forgot"

He puts up his fingers and says

"Emerge from darkness, blacker than black. Purify that which is impure."

Then suddenly the sky turns darker and darker, the veil has been casted.
