Sans world gets reset and he finds himself transformed into a human girl in a world of heroes and crime. She, however, is all alone, her friends and brother all lost to the past, lost to the last world that she now only has in memory. With this new life, she vows to learn to become a hero, so she can save those who cannot save themselves. She wants to better herself because of all of her past failures. Maybe, in this world, she can make a difference, and not have it all rewound. What happens when the other versions of herself FINALLY find her again, after 4 years of being missing, and not resurfacing? 'It's a beautiful day outside. Birds are singing, flowers are blooming. On days like these, villains like you, should be behind bars.'

Ink and the other sanses were just having their meeting when suddenly they were pulled in to a portal. When they woke up all of them were all tied up. They tried to use their powers but , it seems the one that captured them put magical hand-cuffes to block their magic. They looked around and saw a tall figure standing in the darkness. Who was the one thats standing in the dark? Who will save them? Where did they end up? Please read the story to answer these questions! The other sanses haven't met the original yet but they all heard of him. (Reminder: all of the sanses are in love with classic.)
