You were put into a match against a Player using Classic Sans. You were teleported into the Last Corridor of Classic Sans. Classic Sans was at the end of the corridor, and you were at the beginning. You were on the Chara Team in this match, so it meant you had to kill him to win the match. In the background, "MEGALOVANIA (Broken Promise Mix)" was playing (Here is the link if you wanna listen to it: https://soundcloud.com/skiehie/megalovania-broken-promise-mix). You have 300 seconds to kill him before the time runs out. He has 100 stamina or 120 stamina (If using upgrades) and 1 HP, you have 92 HP and the Real Knife, drain his stamina so he can't dodge anymore and finish him off, go.
