Don't underestimate those who have fallen

Ren - Who are you!!!!??? And why you look exactly like me?!

Demon Ren - I am the Demon King, more precisely I am you until you reach this floor. A perfect copy in both appearance and power and also, your last challenge in this tower! You can call me by Demon Ren.

Ren - That's impossible!!! I never saw a magic that could cop...

FSHING!!!!!

Demon Ren didn't wait Ren finish his sentence and tried to stab him in the chest, but luckly Ren was able to block and clash against that Nightmare.

Ren - Are you crazy!? Why are you doing this to me??!!! Why i need to fight myself?!

Demon Ren - To see if you are ready to own this power!!!!! AAAAAAAAAAAAH CRIMSON NOVA ZERO!!!!!!

REN - CRIMSON NOVA ZERO!!!!!!!!

OAIAAAAAUUUUUUUUUUUHHHHHHHHHHHHHHHHHHHHH VRUUUUUUUUUUUUUUUUUUUUUUUHHHHHH!!!!!!!

A large black hole emerged from both attacks and closed immediately afterwards, letting both Ren and his other version a little bit damaged.

Demon Ren - As expected of my original self, you wouldn't fall that easily. But you're still weak, a weakling who's afraid of becoming the strongest!!!

TSHI TSHI TSHI THSHI TSHI!!!

Demon Ren - SHADOW CLONES!!!!!

Ren - SHADOW CLONES!!!!

TSHING TSHING TSHISHISHISHISHSIHSISHISHISHISHSIHSIHSIS!

Ren - HUH! 

VRUUH!!

Demon Ren - I see you!!! HAHAHAHAHA!!!

Boot! TUM! BASH!

Ren - COUGH!!!!!

Demon Ren - Hahahaha! That's all you have... maybe you're not the chosen one. Let me finish this, AAAAAAAAAAAAA! 

PLIM!

A sharp sound echoed throughout the entire room.

FEEEXXXSHHHHH!!!!!!!!!!!!

And the Demon Ren began to fall to the ground, expelling blood from his body.

Demon Ren - WHAT HAPPENED?! COUGH!!

Ren - What happened? Well, yes, you're an exact copy of me until I got here, but no one said I wouldn't get stronger as we fought. You let your guard down at the last second and I was able to parry your attack, which gave me the opportunity to hit you squarely.

Demon Ren - Ha ha hahahahaha! Perfect! I think you are ready for rule this world. My heart is all yours my King!!

The Demon Ren reached out his hand to Ren and after Ren took it, a great flow of power began to enter his body, making him tremble from the amount he was receiving.

System - The player finished the last challenge of the tower, now the arena must go up and make the player leave.

The arena started to move and after the roof opened Ren said.

Ren - What a beautiful view, it's been a while. It's time to finish what I started. Get ready Magic Kingdom, I'm on my way!
