UNDERTALE: Aftertale

Post true pacifist ending (SO SPOILER ALERT). There are still some unanswered questions after the monsters are freed. How do humans interact with them? Why does sans have a lab? Who is W.D. Gaster? And why did Frisk go to the underground in the first place? The story continues where the games leaves off, watch all the characters you love adapt to their new lifestyle. Adventure/Angst
