Grouptale

(Story also available on my Quotev, Wattpad, and DeviantArt) AU where all seven humans fall into the underground at the same time. The characters are Frisk, Ray (orange soul), Clover (yellow soul), Kat (green soul), Ace(light blue soul), Teri (blue soul), and Poppy (purple soul). Follows the True Pacifist route. UNDERTALE IS OWNED BY TOBY FOX.
Also, little note. There are multiple main characters, three male, three female, and the main-main character, Frisk, is neither so just ignore the "female lead" label. I only picked it because there are more female povs than male ones in the entire book.
