BREAKING MY PROMISE | Undertale, #12 (Genocide)

Today... is not a good day for the underground. After completing the pacifist run, I have to completely reset the timeline in order to commit the worst crime of all: murdering everyone in the underground. I'm sorry Sans... Papyrus... Alphys... Undyne... Toriel... Asgore... Asriel... I couldn't keep my promise...
