Yu-Gi-Oh! Heroes

Thinking of this, O'Brien nodded without any hesitation and agreed to Professor Cobra's instructions.

After saying these words, Professor Cobra left a camera on a nearby tree and walked away.

……

"Hello...calling Argo."

After returning to Obelisklan's dormitory, Amon placed the watch-shaped device "dis-belt" in his hand into an iron box containing a scanning device in the dormitory.

While placing the "dis-belt" device into the scanner, he also turned on the special anti-eavesdropping communicator in the iron box and sent a corresponding synchronous scanning request to someone on the other side of the communicator.

"…Roger that, this is Argo."

On the other side, in the waters near the Duel Academy, inside a submarine that was staying in the deep sea, a female voice sounded and started talking to Amon.

"Well, I will send the dis-belt data to you now." After receiving the reply, Amon sent the results scanned by the device to the submarine.

Amon, who saw the structure of the device at the same time, couldn't help but reveal a look of surprise on his face.

"This is?!"

"This device is related to what we are investigating. We must keep an eye on Professor Cobra!" Looking at the scan results, the female voice gave a corresponding answer.

“…Understood.”

After receiving a reassuring reply from the people on the submarine, Amon immediately put away the device in the iron box and began to prepare for the next plan.

Similar to his guess, the device distributed by Professor Cobra did have huge problems.

Next, in order to obtain further answers, Amon will track Professor Cobra to find out the secrets he wants to hide.

Yes, that's right. The person who was observing Judai Yuki and John in the Red Dormitory of Osiris was Amon who had a special purpose.

He had previously marked John as a suspicious ghost member, but failed to get the information he wanted from John.

Next, his target will be adjusted to Professor Cobra, who is more suspicious.

Shortly after Professor Cobra finished explaining things to O'Brien, Amon, who discovered a clue from the watch device, transformed himself into a black shadow man, followed Professor Cobra's trail, followed behind him, and came to the vicinity of the abandoned research institute with him.

Instead of taking risks, Amon just looked at the structure of the abandoned research institute, walked forward to observe it roughly, and then turned around and left.

At this time, Professor Cobra also followed the corridor and came to the deepest part of the research institute.

"At that time, the energy absorbed from Judai and John was even more powerful than I imagined..."

"If the absorption level of the duelists' energy continues to increase, the lives of the students wearing the device may be in danger..."

"Oh, most people might stop here out of fear, but me, the cobra...how can most people compare to me?"

With a cruel and greedy look in his eyes, Professor Cobra came to the depths of the research institute. He looked at the light body in the glass container that absorbed energy and gradually condensed into a solid body. A look of desire flashed in his eyes.

"It's almost there, it's almost there... before long, my goal will be achieved..."

673 Dark Fusion! O'Brien VS Yusei!

“…Yusei, duel with me! Let me see… the true strength of the hero who has saved the Duel Academy so many times!”

After receiving instructions from Professor Cobra, O'Brien used the powerful tracking ability he had developed during his career as a mercenary to actively find Yusei, stand in front of him, and challenge him to a duel.

The location of the duel was undoubtedly the place where he had been practicing, and it was now the location of the cliff where Professor Cobra had placed surveillance devices.

There was no conspiracy or intrigue of kidnapping hostages. O'Brien, who was stubborn by nature, just went straight to his target and stated his intentions.

Until he achieves his goal, he will hold on to it like a jackal and won't let go.

"...Duel with me? Are you sure?"

Looking at O'Brien who suddenly appeared in front of him, the serious man who challenged him to a duel right away, Yusei, who was strolling around the campus with Asuka and Rei, raised his eyebrows habitually.

After protecting the two girls behind him, he asked in confusion towards O'Brien.

"Yes, it's you."

O'Brien nodded and gave a confident answer without saying a word.

The four branch champion players who came to the Duel Academy headquarters this semester almost all have completely different personalities.

John's optimistic personality is similar to that of Yuki Judai, so the two people with complementary personalities often stick together and don't want to separate. Even when they are on action, they are always in groups of two.

Amon, a hedgehog-headed young man wearing square-framed glasses on his nose, has a relatively independent personality. He gives people the impression that he is always thinking about something and looks rather worried. He is the kind of person who has a lot of thoughts. It is foreseeable that it is very tiring to get along with him.

Jim, dressed as a cowboy, is always accompanied by the crocodile "Kallen". He seems to prefer getting along with animals rather than people, and deliberately avoids being approached by others. Even if he appears to be more friendly on the surface, the actual situation is probably only known to him.

The last person is O'Brien, who is standing in front of Youxing at this moment. He comes from the same place as Professor Cobra. He doesn't like to talk much and gives people the feeling that he is more like a professional soldier than a student.

However, it was a person with such a character who took the initiative to find Youxing and told him his clear purpose.

This makes people suspect that there must be someone behind him who is deliberately instigating this.

"Hmm? You came to me suddenly? With such a clear purpose? Let me think... Professor Cobra sent you here, right?"

O’Brien: “……?!”

With his chin supported by his hand, Youxing thought about it roughly and soon came to the corresponding conclusion.

When O'Brien heard these words, his pupils subconsciously shrank and he showed a shocked expression.

Instinctively, he habitually placed his arm on the gun-shaped duel disk on his thigh, posing as if he was about to kill someone.

Although he didn't say anything, his surprised reaction and subconscious defensive actions undoubtedly exposed his true intention and purpose.

O’Brien: “…”

Yusei: "...Well, I don't know what you guys are planning, but I'll accept this duel."

Just when O'Brien thought that Youxing, who had discovered the clue, would reject his duel request with ulterior motives, Youxing, to his surprise, readily agreed to the duel.

O’Brien: “……?”

O'Brien, who was somewhat confused by Youxing's behavior, froze in place and temporarily lost the ability to think.

"What's wrong? O'Brien, this is the request you made? Why are you stunned?"

Waving his arm in front of O'Brien's eyes, Yousei smiled and patted O'Brien's shoulder.

At this time, O'Brien finally reacted and instinctively took a few steps back.

"Ahem... Well, that's it, Yusei. I'll be waiting for you at the cliff..."

O'Brien, aware of his loss of composure, did not intend to continue chatting here.

After receiving a confirmation reply from Youxing, O'Brien turned around and quickly left the place to make corresponding preparations for the next duel.

Although Professor Cobra told him to force Yusei to use his full strength no matter what, in reality, O'Brien was not fully confident about this.

His opponent is the hero Yusei who has created countless miracles. Facing such a powerful duelist, O'Brien cannot retain the slightest hope in his heart.

"Yusei? Why did you accept his invitation? This duel is clearly a bit weird."

Looking at O'Brien's departing back, Asuka, who was standing next to Yusei, couldn't help but speak with curiosity and asked Yusei what he thought.

In her mind, it might be because the three of them lost the device given by Professor Cobra that they were targeted by Professor Cobra.

But looking at O'Brien's reaction just now, it seems that is not the case.

It seemed that the only person being targeted was Yusei, not her and Saotome Rei.

"Hoohoo~ Lord Youxing, that big fool just now was stunned when he heard what you said!"

Saotome Rei, who didn't have many complicated thoughts in her mind, recalled O'Brien's inappropriate behavior just now and couldn't help but cover her mouth and laugh.

If he is really an assassin sent by Professor Cobra, then isn't this mentality a little too unsteady?

Can such a duelist really become an enemy of Lord Yusei?

"Well, what is coming will eventually come. Instead of waiting for the opponent to make a move, it is better to take the initiative..."

Smiling at the girls around him, Youxing then continued to ask them: "Next, I have to go back to get the duel disk to prepare. Do you want to go with me?"

"Well, I don't have anything to do, so I might as well go over there and take a look."

“Yes, I will! Yes, I will! I want to see with my own eyes the heroic figure of Master Yusei killing that guy!”

Naturally, after looking at each other, the two girls finally chose the option to set off with Yusei.

After receiving the answer, Youxing returned to the dormitory, took his duel disk, and then walked towards the place where he had agreed to meet with O'Brien with the two girls.

By the way, when Yusei returned to the dormitory to get the duel disk, Yuki Judai and Kenzan, who were chatting with John in the dormitory, also followed Yusei to where O'Brien was after hearing about the duel.

Just like that, a secret duel that was supposed to be between Youxing and O'Brien, due to various unexpected circumstances, eventually turned into an outing for the main character group.

By the time Youxing arrived at the place where O'Brien was waiting, there was already a long army behind him.

Asuka, Rei, Judai Yujo, John, Kenzan, Maruto Sho…

These people stood aside tacitly as O'Brien looked ashamed, acting as spectators.

Yusei smiled at them and came to O'Brien holding the duel disk. "Say, O'Brien, let's start the duel!"

"…Although I am a little bothered by those guys next to me, my purpose will not change."

Glancing at the camera Professor Cobra had hidden in the bushes, O'Brien said in a deep voice, "Yusei! Let me see your true strength!"

"Heh, do you want to see it, or does the guy behind you want to see it?"

Noticing that O'Brien was wearing the device released by the World Tree on his arm, Youxing narrowed his eyes and said nothing more.

He stretched out his arm, and together with O'Brien, who was silent opposite him, unfolded the duel disk in his hand.

"...Duel!!!"×2

(Youxing LP: 4000)

(O'Brien LP: 4000)

"Hehehe...it's finally about to begin!" Professor Cobra, who was hiding in an abandoned laboratory and observing Yusei and O'Brien through a camera, showed a standard villain smile on his face.

Although the large group of people that appeared with Youxing were very annoying, their appearance did not affect his plan.

"Yusei, O'Brien... let the energy from your duel become the best food for that adult!"

Because Yusei's arms were covered by Osiris Red's uniform, Professor Cobra did not notice that Yusei was not actually wearing the watch-shaped energy absorption device.

At this moment, Professor Cobra thought that everything was under his control.

Little did he know that his tricks had already been seen through by some smart people, who took corresponding countermeasures.

"…I'll attack first! Draw a card!"

By intimidating O'Brien on the opposite side with words, Yusei took the opportunity to seize the right to attack first and drew a card from the top of the deck.

After looking at his hand, he inserted one of the cards into the back of the Duel Disk: "First, this card. I activate the magic card [Dark Fusion] from my hand!"

"From your hand and field, send the monsters that serve as Fusion Materials to the Graveyard to perform a Fusion Summon exclusive to Demon-Type monsters! Monsters Special Summoned by this effect cannot be targeted by your opponent's effects this turn, nor can they be destroyed by your opponent's effects!"

"I will send the [Elemental Hero: Wingman] and [Elemental Hero: Explosion Girl] in my hand to the graveyard and use them as materials for Dark Fusion!"

The Overlord's exclusive Dark Fusion now takes effect on Yusei's Duel Disk!

As this Fusion Magic Card exclusive to Demon-type monsters was activated, Yusei's eyes were instantly dyed with brilliant gold, turning into burning, never-extinguished golden eyes.

A blue-green flame also ignited in front of Youxing, turning into a huge pillar of fire that surged straight into the sky.

The "Dark Fusion" that represents the power of the Overlord, when activated, also automatically summons the power of the Overlord deep in Yusei's heart.

"Ooooooh! It's Dark Fusion... Looks like Yusei is really serious about this!"

Yuki Judai, who also had the Overlord's personality dormant in his heart and hadn't seen Yusei use [Dark Fusion] for a long time, couldn't help but let out an excited shout.

Unlike ordinary fusion magic cards, the monsters summoned by [Dark Fusion] usually have stronger strength than the original ones and more obvious appearance characteristics.

These blackened heroes are more powerful than their original versions, both in appearance and ability.

"Judai? Do you know this card?"

Seeing Yuki Judai's excited reaction, John, who was curious about it, couldn't help but ask him.

"Ah... that's natural!"

Pulling out an identical [Dark Fusion] from his deck, Yusei Judai handed it to John to watch: "After using this card, both Yusei and I will change into another personality and awaken the power sleeping deep in our hearts. That's why I said that Yusei is serious!"

"I see... Is this the other side of the Hero?"

As an elf user, John instinctively felt an ominous dark aura from the card in front of him.
