Don't ask where I got the idea... I just learned about Error Sans and I've always loved Aftertale Sans. I instantly fall in love with every Undertale AU, even UnderFell. Most art of it is just creepy. I'll do more Sans au ships if wanted. For example; Sans x Underfell Sans Swaptale Sans x Sans Error Sans x Underfell Sans Error Sans x Swaptale Sans Sans x Aftertale Sans Gaster Sans x Sans Aftertale Sans x Underfell Sans Gaster Sans x Underfell Sans Gaster Sans x Error Sans

Ink and Error are very different. Ink creates and Error destroys. But those two can work out anything, they become best friends. Follow the story, maybe they might become... More.
