I use Yugioh to battle the multiverse

The beast-warrior holding axe bears become more excited when being surrounded

He madly rushes to one of them keep on chopping one of the centaur soldiers it can only use its spear to defense from the madman attack despite having the strength to cut iron like tofu he can't destroy it after delivering so many strikes only leaving a dense crack to its weapon and body

The other nine naturally don't standby they all raise their spear and aim at the beast-warrior charging straight at him.

Knowing he can't beat them at once. He cut multiple deep holes on the ice surface where they will go making all of them lose their balance and fall each of them is separated by a thick wall of ice.

Because they all have weak strength so the centaur soldier can't cut the ice in one swoop like him but they will eventually come back out if given enough time so he jumps down to beat each one of them

Those centaur soldiers may not be smart but they sure know that they can't beat him so each of them plays suicide by ignoring his attack and keeping on finding a chance to strike him.

Thanks to their hard body they can easily ignore his attack and poke a few holes in him before being destroyed.

When he is done slashing his first centaur soldier into pieces their already a few drops of blood dripping from his body and quickly frozen by the environment, but he still keeps on going to his next target

After letting out their minion to fight next is up to them

"Your monster sure is strong and smart," Esdeath said clashing her rapier with Katsu sword the two weapons clash very fast creating a spark every time they collided

"Yours is not that weaker if they have wisdom" Katsu complimented dodging her kick to his face.

"Let be serious teacher~" with a slight smile on her face a giant ice wall rose from Katsu feet creating a box with him inside and the ice wall slowly shrink to squeeze him

Katsu try slashing the ice wall but it is very thick and hard despite receiving so many strikes it didn't flinch

He summons Dark magician girl who is watching outside and equip her card. Feeling the magic power coursing through his vein, he summons her wand and fire out a dazing beam of light drilling through the wall.

Esdeath once seen Katsu equip Dark magician girl before so seeing the wand in his hand, she knows that he is much stronger than before.

The temperature around them started to drop down significantly as the snow even touching his skin can freeze him, but thanks to Esdeath card and Dark magician girl's large mana to cover his body with enchantment he quickly break out of it like nothing.

His speed and strength are now much stronger than before so when he and Esdeath clash again anyone with fighting experience can see that Esdeath is at a big disadvantage. She can't attack back but can only defense from his wand from smacking her around like a pinata.

{It is really exciting} Esdeath wipes the blood from her mouth her fighting spirit is fully ignited. Since becoming this strong no one has posted much of a challenge to her so feeling this thrilled again makes her very happy especially from the person she loved the most.

"More so me your true strength Katsu" a large amount of ice element from the five centaur soldiers left to be slaughtered from beast-warrior cover Esdeath whole body creating a giant armor with her controlling from the inside.

Despite its big figure, it moves extremely fast like a human with a body make from solid ice and you can imagine a giant mech ten times your height punches you how painful it is.

Katsu taking back the now injured Kaiser Vorse Raider back into card form and equipping it. The warrior instinct and strong body with mage ability combine creating the perfect fighter.

Holding his axe bears cover by dark magic, he moves like a shadow swinging his weapon at the armor creating dense crack on it. Esdeath's eyes can't keep up with his speed even when using magic to slow him down she still can't see even his afterimage.

Swinging her fist to his predicted location won't work as he can dodge it effortlessly.

After a while, her armor is at the breaking point but she can't even hurt him.

"Deciding to give up yet Esdeath," Katsu asked

"I still have my card" controlling ice to levitate herself to the air she creates a giant meteorite of ice fueling its size with her remaining power from the ice armor and pushing it in his direction

"Should we stay a bit further away" Kylie frightened by the large meteorite asked. The meteorite itself is larger than the empire capital itself so the impact can still affect all of them even with a shield from Balluck

"You should trust Katsu more he is the best teacher we ever have besides he won't stand still if we are in danger" Cornelia answers but she is a bit nervous

Looking at the giant meteorite, he takes out his axe bears points at the back cover spellbook, and chant into it.

A large amount of mana started to pour into the book it glows so brightly that people will be blind for a short while. After everyone can see again their eyes almost pop out because now the weapon in Katsu's hand becomes so large that it covers the sky coat in flame, like a giant weapon descending from the sky.

What amazing it despite being so big you can still see Katsu's small figure holding it.

With a swing, the meteorite like butter cut into half but he didn't stop there he continue to strike it repeatedly until it only ice dust

"Mahapdama" time suddenly freeze for everyone including Katsu only Esdeath silently walk to him taking out her reaper striking him

"I win" receiving a kiss on her lips, she is completely in shock as she sees Katsu moving again to block her reaper.

"I have this so adapting to your ability is pretty easy" showing his ice ability to her but she didn't notice it rather she is blushing madly from his kiss.
