I use Yugioh to battle the multiverse

"...Hmm. It seems that the opponent has reduced the thickness of the Realizer field covering the ship to the extreme to improve its maneuverability. And the action just now is probably using the Realizer field to propel the hull."

"Is that kind of thing possible?" "Although I haven't tried it, it's not impossible in theory. As expected of Ellen Mira Mathers ---" Kannazuki said, rubbing his chin.

Kotori slammed the armrest of the captain's seat with a loud "bang".

"Now is not the time to admire her! She's about to attack!"

As Kotori shouted loudly, Goetia once again drew an unnatural trajectory and approached Flaxinus, the speed was so fast that it was hard to imagine it was an aerial ship.

"Turn the Realizer field into defensive mode! To prevent impact!" Kotori gave the order without much thought.

"Yes!"

The next moment, the gun port installed at the front of Goetia fired a cannon, which immediately hit the Realizer area covering Fraxinus, and the magic light splashed like sparks.

"Tsk... you're quite good at it. Set the to attack mode! Attack Goetia's back!" Kotori continued to give orders to the people below their seats.

The Leaf of the World Tree is located at the rear of Fraxinus. As its name suggests, it is a leaf-shaped unit, each equipped with an independent Realizer device, and can be remotely controlled by the mothership to deploy as a general-purpose weapon in any area.

It can be used for a wide range of purposes, from broadcasting communications to attacking enemies. The existence of this weapon is also the biggest feature of the aerial ship Fraxinus manufactured by Asgard Electronics.

However, something unusual happened immediately. Just as the crew was about to respond, a piercing alarm sounded on the ship.

"What's going on?!"

"This is... the enemy ship is about to fire again!"

Kotori's face changed slightly and said, "What did you say..." How could it be so fast...

However, before Kotori could finish her question, a ray of light flashed from the front of Goetia, and then the ship of Flaxinus began to shake violently.

"Tsk...!" Kotori gritted her teeth and stared at Goetia on the screen.

Needless to say, the main weapon of the airship is the magic cannon; it uses the manifestation device to output magic and fire artillery. Although there are basically machine guns and other weapons, they are almost useless in the battle between airships that protect themselves with Realizer fields.

The first and most important thing is to reduce the opponent's Realizer.

In this way, apart from special weapons such as the , the only way to attack is to fire a magic cannon or increase the strength of a Realizer field to ram the enemy.

Therefore, the tactics adopted by Goetia were very orthodox, except for the abnormally amazing speed.

"Less than ten seconds after the first bombardment, they fired another bombardment...? How is that possible? What kind of Realizer did the enemy ship have to be able to do that...!"

That's right. If you don't activate the manifestation device in parallel to generate magic power, you basically can't fire the main gun continuously. Even if the Flaxenas is fast, it will take thirty seconds to fire the next shot.

In that case, all we need to do is increase the number of manifestation devices that generate magic power... but we can't do that.

If we simply increase the number of generated cells, there is still a limit to the processing capacity, and we must use it very efficiently.

"...Tsk!" Kotori smacked her lips in dismay. The strange movement of the ship and the continuous firing of the magic cannon were all related to the appearance of Ellen Mathers that she had just seen.

Although the performance of the manifestation device itself can be improved by using a new device called Ashcroft-β, Ratatoskr still has the advantage in this regard.

Therefore, DEM will use other methods to make up for the performance gap.

Not only can it use processing power in emergencies like the Flaxinus, but it also takes the processing power of the human brain into account from the outset to achieve efficient use, making it a pure "battleship".

This is a foul technique that can only be performed by Ellen, the strongest wizard in the world.

Of course, the burden on the brain is incomparable to normal IT. Even Ellen cannot sail continuously for a long time.

However, at this moment, what was before Fraxinus was not a bulky airship that required multiple people to steer, but a super-large IT-equipped

Ellen Mira Mathers herself.

"Commander! The left wing's Realizer field has reached its limit!"

"Tsk..." Kotori looked at the personal screen beside her. Part of her Realizer domain was indeed severely damaged.

"Open the Realizer field again! Refill the Yggd Folium again, hurry up!"

"Got it... Got it!"

"—Kannazuki!"

"Yes!" Kannazuki noticed Kotori's intention and looked at her sharply.

In a flash, Yggd Folium soared into the sky at an incredible speed.

The one operating the World Tree Leaf now is not the control-type manifestation device of Fraxinus, but the deputy captain Kannazuki standing behind the captain's seat.

Yggd Folium flew in the air and spread out, surrounding Goetia, and then expanded the range of the Realizer area generated with the leaves as the center. That's right. A cage was built in the air to surround Goetia.

"Commander, now is the time."

"Okay, Mystletainn──shoot!" Kotori shouted loudly after pointing Kabejia at Goetia .

As if responding to Kotori's voice, the , which had been refilled with concentrated magic energy, drew a line of light in the air.

Attack with magic cannons in front. Even if the enemy ship wants to dodge the bombardment, there are still the ** leaves of the world tree waiting around.

No matter how powerful Goetia is, he can't escape now.

However, at the moment of releasing the , Goetia actually moved straight in the direction of the bombardment, and then tilted the hull before it was about to touch the bombardment, allowing the top of the hull to rub against the Realizer field of [Yggd Folium], dodging the attack of the .

"What…!" Of course, the transformed leaves of the Yggd Folium sensed the impact and caused a violent explosion –but Goetia remained intact.

Perhaps the Realizers area covering the hull was concentrated at one point and survived the explosion.

"That woman, how big is her heart?!" Kotori gnashed her teeth in anger. If the operation was wrong, the ship would be blown to pieces. It was a very risky strategy.

If one were to think in a normal way, one would deploy a defensive Realizer field in the direction of the artillery fire to block the attack.

In fact, at the moment when her opponent took that action, Kotori was about to order the [Yggd Folium] to pursue.

In this battle of intrigues, it seemed that Ellen had won. Ellen had made such a dangerous bet because he had seen through Kotori's scheme.

"Tsk..." Kotori frowned at the thought.

The woman didn't consider her previous action as a gamble at all. She simply avoided the bombardment as a matter of course, with the arrogant thought that "I can't do it".

"Goetia is coming!"

The crew below screamed in fear.

Goetia dodged the and rushed straight towards them.

"Ugh, get out of the way—"

"Don't worry, Commander." Kannazuki, wearing a headset microphone, walked to the captain's seat and immediately snapped his fingers.

In an instant, the bombardment of the , which was supposed to be avoided by Goetia, turned around behind Goetia and returned to its original direction.

"Ah...!" Kotori couldn't react to what happened for a moment, but then she understood.

Behind Goetia , countless leaves of the Yggd Folium were floating, expanding into a Territory.

The arbitrary field that operated them forcibly bent the trajectory of the magic cannon.

The enemy ship seemed to be caught off guard by this move. The , exploded behind the defenseless Goetia, causing an explosion.

That's right. If the other party is a monster, we also have a monster on our side. Kotori looked up at the tall man standing next to the captain's seat and sighed softly.

"…As expected of you, Kannazuki."

 "I don't deserve it. After all, we can't leave any scars on this beautiful Fraxinus. Besides—"

"I think it's more attractive to attack others, Commander, rather than being attacked!" Kannazuki shouted with his fists clenched.

Then, Kotori sighed. However──

"...! Commander!" Hearing Nakatsugawa's loud shout, Kotori shook her shoulders.

Goetia, who was supposed to be hit head-on by the , was rushing towards Fraxinus.

At that speed... there was no way to dodge it --- did that guy want to die together with us? !

However, something unexpected and even unimaginable happened to everyone - when Goetia approached within a hundred meters of Flaxenas, he suddenly stopped -

Of course, no one would think that Ellen had a change of heart and chose to let them go...

"That is..."

A crew member who was closely watching the movements of Goetia on the screen murmured softly---then the screen automatically zoomed in---

A figure that looked extremely small compared to the Goetia, which was the same size as Fraxinus, stretched a wand and blocked the bow of Goetia, causing the terrifying ship that had just been fighting with Fraxinus to stop there helplessly.

"Who is that? Such a strong energy fluctuation.?"

"Is brother Katsu!"
