    This is an og AU but differents. After Error and Ink accidently created PJ during their fights,Error tried to killed him but Ink stopped him and Error called PJ a mistake that shouldn't live and then teleported. Everytimes Ink or PJ tried to talk to him,it's always the same as he will fight/tried to kill them and PJ gave up as his hatred towards Error grew. Ink love Error and he still is even if Error doesn't love him back. But what happened if they found out that Error used to be King Multiverse's husband after a fight which lead them to divorced but they decide to only became friends. But what happened if both Error and King had a daughter that is PJ's older half-sister named Gleam and that she's the Heir of her father's trone? What happened if Error only love his daughter more than PJ because of some dangerous reasons? What will be their reactions? Will Ink still love Error? Will PJ accept his older half-sister and forgave Error? Let's found out! Warning ⚠️ : All the characters are from in their normal creators excepted for my ocs.

    So sorry for the cover! Check Author's note to see what it's supposed to look like! Half credit goes to Sophia (A.K.A. My best friend) For most (possibly all) the art including the cover, and helping me create the story with a role-play we did! "AHEEHEEHEEHEE! P.A.T.H.E.T.I.C." "Why... Are you doing this...?" No one would suspect an innocent being... right?

    [A/N: This AU of mine is old. Writing might have changed what I have now. Also I was veryyy young when I started to write that.] Long time ago, Creatures, Humans, ghost, spirits even Monster lived together peacefully. One day, when the new King was in his castle, everything was peaceful. But after 4 months, King was annoyed by Monster and by half creatures. He telled to execute or throw them to the forest. Almost of the half creature were killed. With monster was worse. Almost every monster was killed... After 14 years monsters attacked village. It was a bloody war... Most of those monsters had kids but unfortunately died. Some humans and creatures were dead too. ------------------------------------------------------- Meet the NEW Multiverse! In this Multiverse will have romantic, drama, ships, CANNIBALISM, gore/blood, being an orphan, cursing, panic attacks/anxiety(?) ---------------------- 24/09/25: Because I just saw that someone (a proshipper probably) hacked into my account since 2021 somehow (because I get notifications from comments that year too I didn't even commented) I decided to abandon this account and make another one. ItzViza. It'll take a little time on Friday to get a new account because I'm a little busy-

(It's going to happen a lot) P.S I'm planning on(maybe?) turning this into a sanscest one-shot book, cuz I wanna add other ship POVs.

    ------------------------------------- " Y-your so s-strong." The skeleton with butterfly wings stared emotionlessly at the threat to the multiverse. "Y-you haven't even let 𝙄𝙩 out yet, but you can still beat me." "A-atleast I can still focus my magic to do one last attack." "He-." He then collapsed before he had a chance to finish what he was saying. The skeleton went closer to confirm that he was dead and found that he was in fact dead. The skeleton slowly started to lose parts of his body starting with his legs when it got to his chest it seemed like... He realised where he was, what he was doing, who he was fighting and the pain he was in. And after all that, He just sighed and said. "Heh, guess I couldn't do it, huh?" his Glitchy voice falling silent on the last few words. ----------------------------------------- So uh this is a reincarnation fan fic with a twist So uh yeah dunno what to say here lol.
