Reset? (Undertale x Errortale)

After a Pacifist run, Frisk the Human promises to his best friend, Sans, that there will be no more future resets for the sake of his sanity. However, when the boy starts seeing a black skeleton similar to Sans, but with red eyes, Frisk quickly realizes that he is being chased by a version of Sans named Error. Error has been hired by Frisk's old genocide enemy, Chara, to capture and bring Frisk to the Errorscape, a place where Chara has resided ever since Frisk never resetted the game.

When Sans realizes this, it's turned into a race against the clock to protect Frisk from Chara's grasp and most importantly, protect the monsters.

Will he be able to get there in time before Chara does? Or will he and the other monsters be eliminated?
After all, Frisk did promise no more resets...
