(Y/N) pov

I arrive at the school and see Gao and Drum getting ready to head out. I press a button on the build phone reverting it to phone mode, and remove the lion bottle from it. After all that I run up the escalator to meet up with them. After I got up the escalator I went up to Gao.

(Y/N): Hey Gao.

Gao: Oh hey (Y/N), we're following an illegal monster we'll need your help.

(Y/N): Alright!

I equip the build driver and take the Taka and Gatling Fullbottles out of my pockets.

Gao: Whoa what form is that.

(Y/N): HawkGatling Form. Let's go!

We start flying towards the illegal monster, when we get there and Drum uses his Decker handcuffs to restrain the monster and  some kind of darkness envelopes us and we appear in a arena that has a skull theme. I remove the bottles from my driver to undo my transformation.

Gao: Where are we?

Drum: How are we gonna get out of here.

(Y/N): My best guess is we have to fight our way out.

Suddenly some one with a bone like helmet shows up at the other side of the arena.

Mystery Guy: I am Death Shido the best buddyfighter in history. I challenge Gao Mikado to a buddyfight, if I win you have to give me Fifth Omni Dragon Lord, Tenbu! The Only way to leave the Darkness Barrier is by winning this buddyfight.

Gao: Alright I accept your challenge. Drum, (Y/N) I'm using Dragon world.

Drum: Alright! Burning my body with red-hot flames! Breaking open a path with my own fists! Crimson Battler Drum Bunker Dragon is Ready!

Suddenly a UFO appeared in the arena.

Paruko: Warp successful! Where ever there is a buddyfight Paruko Nanana will be there!

(Y/N): I may not know how buddyfights work but I'll do my best to help.

Paruko: Actually sir, you aren't allowed to give game advice during the fight.

(Y/N): Who said I was gonna give advice.

Death Shido: Ravenous Demons walking a wicked path, witness their awesome power! Luminize! Hundred Ancient!

Gao: Burn like an inferno! Limitless fighting spirit! Luminize! Crimson Dragon Fist!

Paruko: BuddyFight!

Gao & Death Shido: Raise the Flag!

Gao: Dragon World!

Death Shido: Ancient World!

Gao: Charge and Draw! I call Crimson Battler, Extreme Blow Dragon to the center area! Attack Death Shido!

Death Shido: It can't be helped.

Extreme Blow Dragon: Here's a knuckle sandwich!

Death Shido is now at 7 life points while Gao is at 10

Core Case: End of move.

Death Shido: Draw, Charge and Draw. Demonic Dragon Sorciere To the center, Varpal Spartar to the left, and Little Land Mu to the right. Mu attack extreme Blow!

That small little land dragon mu managed to destroy extreme blow dragon.

Death Shido: Sorciere, Spartar attack the fighter.

That attack alone knocked Gao's life points down to 5.

Core Case: End of Move.

(Y/N): Gao let's try to end it this turn.

Gao: Alright! Draw, Charge and Draw! I buddy Call to the right Crimson Battler Drum Bunker Dragon!

Drum: Alright and here's the buddy gift!

Drum went to the right area while Gao's life points went to 6.

Gao: I equip Crimson Fist, DragoBlaze! I pay 2 gauge to call to the Left Kamen Rider Build Rabbit Tank Form!

Paruko: I've never heard of that card.

Suddenly I'm transported to the left area.

(Y/N): Shall we begin the experiment?

(Ignore the Smash and Banjou)

(Y/N): The Law of Victory has been set.

Gao Currently has 3 cards in hand he could win this turn.

Paruko: What's this, let me check with the TakoScope! Kamen Rider Build Rabbit Tank Form. Size 1 Power 6000, Defense 5000, Critical 2, with the ability Soul Guard, Can be used in a deck no matter the world, and when he enter's the field Gao Gains one life and draw's a card.

Gao now has 4 cards in hand and 7 life.

Gao: Drum Attack the center!

Drum: Alright, DRILL RAM BREAK! PENETRATE!

Death Shido's life is now at 4.

Gao: DragoBlaze!

Death Shido: Cast Dragon Prudent.

Gao's attack was nullified but I still have my attack.

Gao: (Y/N) attack the fighter!

(Y/N): Alright. For the sake of love and peace.

I attack Death Shido with my Drill Crusher bringing his life points down to 2.

Gao: Cast Dragonic Charge!

Death Shido: But that means!

Gao: Final Phase! I cast Impact! Gigantic Crusher!

Gao enters a Giant Metal Fist and it Crushes Death Shido bringing his life points to 0. after the fight we are brought back to where we were before, and all of the stolen decks are on the ground. While we're wondering what happened to cause us to go to that arena, the card of the illegal monster slowly falls down and Gao catches it.
