(Hey important note)

Dusttale. A Korean Undertale AU.

Sans completely has lost his mind and there is no way of stopping him. Unless you kill him for the second time. At first you didn't feel regret until this particular incident happened. Chara is even intimidated and scared. Sans isn't normal, and everyone is dead. But you didn't kill them.

LV 19. V.S. another LV 19.
