This is not a AU, it's a future of Undertale thing, it was trying to put pictures on inline but I'm on Apple phone so I picked this picture instead

Umbrammortis: She's look so hot in the picture-

I know and ur half incubus so I won't let u do that

Umbrammortis: Fine Mister Buttlord

Thank u, anyway, I may going to make a Undertale book that take place in the future (only Asriel, Chara, and Frisk that are change their ages and appearances which they be 18 to 20 years old) but I can't do with my own version because is Undertale, there's too many AUs and versions, so I'll use someone's, I pick Silverdream1's Chariel book because I'm in there XP, so here's some things that will be in the book:
-Azreal will give Asriel (2 Azzies XP) a soul that is equal to a human's but looks like a monster's
-Endre transport Frisk (and their soul) to Chara's body and be 2 people in 1 body (Endre became a teacher after he lose his job for harming a Demon who is not served the Ruler of Evil, even if he's dead thousands of years, read my fantasy book)
-Umbrammortis can be there but rarely because he's activated by when Endre gone insane but commonly talking in Endre's mind

If Jade a Fallen Angel and Daughter of Azreal thing is confirm by Silver then I can put her as companion of Asriel and Chara to hunt the remaining servants of  the Ruler that Endre try to hunt down, if not then she's be the same old Jade so I make the book if Silver confirmed it or not, so goodbye sick sinners
