Aha, allow me to teach you a few things. This is a story of the Seventh soul. What is a soul you ask? Well, its your being. There are 7 soul types. And the legend... its kinda tricky to understand.

Long ago, two races ruled over Earth: HUMANS and MONSTERS.
One day, war broke out between the two races.
After a long battle, the humans were victorious.
They sealed the monsters underground with a magic spell. Those who pass never return, blah blah blah, flower pile, etc. Now that you get that, let's talk about my favorite place in the world... DELTA! *goes on talking about the deltarune legend with the lighteners and the darkeners*

She's like 2 days old to the world she is like fresh from the oven

What doesn't she know, the souls?
