Five years. Five years ago Snails joined Toriel in her home in The Ruins and they were able to call themselves a family. The orphan outcast finally had a place to call his own, and a mother who only wants the best for his future.
Unfortunately, in The Underground, there lives a flower. This flower does not believe in these concepts that Snails has found, and after his last defeat, he by no means will let this intruder find peace. No, this time, while it gains the last of the power it needs, it will watch him suffer.
With these two foes facing off, the question becomes; Will Snails have the determination to meet Flowey's challenge?
Reading the prequel allows you to see how Snails and Toriel met five years ago, but otherwise is negligible to reading this. However, spoilers for Undertale will be shown even starting with this first chapter, so if you have not played the game, I implore you, play it first.
