I use Yugioh to battle the multiverse

The next battle is Remus vs a cowboy with two pistols. When Remus went to the stage she tripped herself dropping her katana earning huge laughter from the audience and the opponent.

"Girl you should put down your weapons and go back to your mommy to cry" he teased her before aiming his gun at her head.

The moment he fires Remus suddenly crouch down to pick her katana complete dodging his bullet

"What" he exclaims and fires another bullet at her body but this time the katana she picks up perfectly angles with the bullet and split it in half. He doesn't believe in this girl's luck and unloads all his bullets into her but she somehow trips again by a rock dodging all the bullets and the rock she tripped flew so fast that the moment it hit his head he received brain damage and directly KO.

There was an awkward silence in the area as the battle ended too strangely but they simply accept it and move on. On the other hand, Katsu believe that she intentionally do that since he already fixes her air-head but she still acts like one to fool everyone even her friends only Esdeath and Katsu can't be trick as they don't believe in luck

The next battle is Balluck vs Kylie but for almost 5 minutes when they are called they didn't come to the stage but Katsu appeared on the stage with a wizard hat and Dark magician girl's wand on his left hand and her spellbook magic formula floating near his right hand. He has equipped Dark magician girl card and ordered the two to gather everyone and kidnapped the girls of the Oarburgh clan. They didn't put out much of a fight since they are all weakened after their fight with Katsu children. And the ninjas of the Oarburgh clan never imagine that their own seeds are taken since they are the ones to usually kidnap children to train them but seeing Katsu on the stage they immediately figure something is wrong and check the girls and soon enough Babara Oarburgh the leader of the group received a report that all their children were gone and their guard has been killed. Some of them have swords marks while some burn alive.

This news directly angers her as they have spent a lot of resources just to train them almost compare to all the assassins they have trained for years. Of course, they are angry so angry that Babara orders all ninjas in the clan to surround him to split out all of their locations.

Seeing more than a hundred black clothes people appear the arena staff evacuates the audiences. Although Katsu is surrounded he didn't panic he throw out his backpack to the mountain of gold. To the surprise eyes of the ninja, the backpack sucks all of the gold leaving not even a single coin. Seeing the magical screen all of them become even more alert they all take out their kunai and throw at him

He waves his wand as a huge barrier covers him blocking all of it as he picks up the bag and wears it. When that didn't work they all take out their katana and strike at the barrier at the same time creating multiple cracks on it. Only Babara's pair of kitchen knives dug a hole almost hitting him but he already uses his wand to block her attack.

She uses this chance to throws a bomb into his hole and jumps out and find a place to hide with all of the ninjas. When all of them jump out Katsu immediately guess this isn't a normal bomb and activate Trap card Negate attack. The black hole completely sucks the bomb in and disappears into the void. Waiting for a while seeing nothing happen all of them come out of their cover but it greeted by dark smaller lazar beam piece through their heart only some professional ninja and Babara manage to dodge the rest died without any last word.

Although more than half of their forces are dead they didn't run as they all take out a bomb similar to Babara and throw it at him. This time they didn't intents to hide as this much bomb is enough to detonate the arena into the ground (easier meaning they want to play suicide and died with Katsu)

Of course, he won't wait for his death the reason why the magic formula increases Dark magician girl attack by 700atk is not that it helps her access more spells but it can double the magic power of a spell if you channel enough mana into it.

He uses his staff to point at the back cover of the book when he chants into it the page started to glow creating a giant wall sour to the sky that completely stops the explosion from reaching him.

After the explosion, he tears down the wall to meet the sight of half the arena gone replace with a big hole while the other half is still intact because of his spell. His points didn't increase much since the strong ones play kamikaze to his face [12000 points] and he is too exhausted to complain. He seperate from the Dark magician girl card and turns back to his original clothing but since he didn't expect to use this much mana another headache came and Dark magician girl has to carry him back home before the guard comes
