I use Yugioh to battle the multiverse

(There will be clues to the next member's appearance in the real chapter, so I will be covering the name, but you can easily guess it if you watch a lot.)

"Move it near the TV, not in the middle, to the left side a bit, slightly right, perfect," Junko directed Kazuma to move the Christmas tree.

"Why not let Gwen transform and help do it faster?" Kazuma lay on the floor full of sweat.

"Who is the person that destroyed the decoration in the first place?" Gwen asked back, making Kazuma silent. With Kazuma's luck, every action of his can bring disaster, like the Christmas tree that he accidentally slipped and pushed into the fireplace, so he has to find a new one and decorate it again.

BOOM

A fight is happening outside the mansion.

"I was waiting for this. Come at me like your life is at stake, " he said, slashing his sword at Katsu's axe bears like a mad man. All the snow around them had already been erased by their battle.

Gwen wants to see them fight, but their movement is extremely fast. Gwen's eyes can't keep up.

Luckily, their new member is an advanced Ai, even stronger than the one Junko created, with a complete digital body, but it lacks a bit of emotion, so Junko only needs to tweak her a bit to perfect her.

Now she acts more carefree and bubbly, wanted to make friends and help them.

So when Gwen asks, she is happy to help project a video slowing down to the right moment, just like in the movie. It's easy to watch.

"It's Christmas; why don't we just relax a little?" Katsu suggested, but Katsu knew he wouldn't listen.

Sure enough, he punches Katsu right in the stomach, sending him crashing to the nearby snow.

Despite it snowing today, he activated Infinity Trap Card Solemn Wishes making water drops from the sky into Katsu's body, healing all the bruises Katsu received,

He lifted his transform and sacrificed Kaiser Vorse Raider to summon the summoned skull.

Then a summoned skull appears from the sky, controlling a giant lighting dragon that comes crashing down, combining with Katsu's spell card Raigeki, a giant thunder dragon fueled by the lighting to become twenty times the size of a person in height.

Seeing the incoming attack with a crazy smile, he gathers his energy into a single strike. A fierce yellow aura covers his sword, and he jumps straight up to greet it. When the two collide, it creates a sonic boom shock wave that almost breaks the barrier that Mana created to protect the others.

A large amount of energy produced by the two injured the man. His whole clothes are ripped to shreds while his body is full of burn marks with blood dripping like a fountain, but he is still alive with a happy, content smile on his face. The summoned skull's durability and endurance are not like the man's, so he is completely turned back into card form and into the graveyard.

Seeing the destruction of their battle "boys," Shiho sighed and kept on drinking her coffee.

"They are finally done. Our new member sure likes fighting, and Shiho tries some hot chocolate. Drinking coffee all the time is not good for you". Stealing the cup of coffee from Shiho, Junko replaced it with hot chocolate.

She silently looks at Junko and tastes the hot chocolate, feeling a bit better.

Luckily, Katsu has Mana to clean the scene, turning the place back to normal before the battle.

After having the battle he wanted, he stopped asking for a beating and napped on the chair if it was not for safety reasons he might have taken off his eye patch to go all out at Katsu but he just want an enjoy battle now not killing anyone yet.

"With him out of the way, does anyone want turkey?" Katsu asked, cracking his sore body from the fighting
