''Last floor cleared, treasure room spawning.'' Everyone dropped on their knees after hearing those words, they have finally cleared the tower, ''Abyss''.

''WE DID IT!!!!.'' Screamed everyone with their body full of adrenaline in unison. the words were able to be heard all over the giant boss room.

''Go get the rewards and bring it to us, scum.'' Said Byson, the world strongest challenger to Kotaro, the world weakest challenger.

Kotaro with his eyes full of anger and despair went to collect the rewards slowly while cursing and hoping that everyone will someday die in the worst and most torturous and painful ways ever, while he was cursing and recolecting the rewards all the cheering suddenly stopped, Kotaro went out to check what was happening and he froze.

...

''Bump-Bump'' Kotaro could feel his own heart going faster and faster every second it passed, the atmosphere turned dark really quick, everybody froze in place when they heard it.

''Tower cleared, imminent world erasion protocol launching.'' Said a very calm, mesmerizing and mysterious voice.

Nobody knew where the voice was coming from, but one thing they knew for sure was that the voice was produced by a creature out of this plane of existence, they knew that it was not joking, the world was really going to get erased and then a sudden thought hit everybodys mind.

''Is this really happening to us?''

...

''The real question is, are we going down without fighting!?'' Said Byson while trying to attack the voice that manifested a system screen.

He started swinging his sword blatantly against the screen, everyone started incorporating themseves into that useless fight, but nothing happened, challengers started laughing in despair and then:

''Final countdown, starting''

''10''

''W-WAIT!'' Byson screamed almost destroying his vocal cords.

''9''

''Ah... is this how I'm going to die?'' Kotaro thought while hearing the countdown.

''8''

...

''2''

Suddenly time froze while a bright light appeared in front of a completely defeated Kotaro, he looked down and realised that the necklace his dad gave him before passing away was the bright light, then he overheard another voice, this time it wasnt calm and mesmerizing, this time the voice was playful and immature.

''Ohhh, look at what we have here, a little boy that has completely lost hope of living, how cute~.'' Said the voice almost mocking Kotaro.

''Let's take a look into your soul, shall we? Hm... I see, poor creature, I pity you, I must have been rough living a life like yours wasn't it? Let me give you a hand, my name is, Abbadon.'' Said the voice while going back to the old necklace.

''I... No, please help me...'' Said Kotaro desesperated after thinking he found a ray of hope.

''Alrighty~ Let's get this going!'' Said Abbadon before snapping his fingers.

The time flow went back to normal and the countdown finally reached zero, right after that Kotaro's vision turned dark, you could say that even a blackhole was a million times brighter than what Kotaro's vision was covered with.

...

''WAKE UP ALREADY!'' A mysterious female voice made Kotaro open his eyes.

''W-What? Who are you? Wasn't the world about to be erased?'' Kotaro asked to the girl while reaching out to his phone to check.

''Can't you recognize your own sister!? It's me Faye!'' 

Kotaro was surprised, not by the fact that his dead sister came back to life, but to the fact that he traveled 20 years back in time, he thought that this was a gift given by the gods and that he would finally be able to complete his long desired vengeance.

...

''Hey! Why are you ignoring me!'' Said Faye while hitting Kotaro in the back.

''I missed you so much Faye!'' Said Kotaro while hugging his sister and shedding tears of happiness short before running out of his home.
