Is this the poker world?Ada thief!

"Once again, we failed to bring Jaden back!"

In a secluded place, Yubel, having detached himself from Amon's usable physical body, once again manifested as an energy form—[Yubel Phantom]—a "human" writhing in impotent rage.

Her plan was perfectly executed. Ever since sending Hayato Kobayashi to another world, Yubel confidently believed that there was no one left in the world who could stop her. She had even muttered boasts like "Without Hayato Kobayashi, I'm invincible" to herself when no one was around.

Since no one could stop her, Yubel decided to slowly collect duel energy to heal her injuries. After collecting enough duel energy with the help of Professor Cobra, she reunited with Jaden for the first time in a long time, only to find that Jaden had long forgotten her and was still tied down by others around him.

This drove Yubel to the brink of despair, and he decided to drag everyone away from the human world and let them die slowly in endless torment. During this time, he hoped to create some drama of infighting and betrayal to please himself and, incidentally, make Jaden sever his ties with them and remember him again.

However, during that transfer, the experiments conducted by Daitokuji and Byin Stein, located far away, simulated a gravitational anomaly on Duel Academy Island, causing Yubel's power to become scattered and not concentrated enough. Under normal circumstances, this wouldn't be a big deal, as Yubel's power would still be sufficient to complete the transfer. But unfortunately, Hayato was also traveling on the "Rainbow Bridge" of the [Supreme Holy Emperor - Odin].

Although unlike the "Rainbow Bridge Cannon" in the Marvel Comics universe, which can be used as a planet-destroying weapon, the "Rainbow Bridge" of [Supreme Holy Emperor - Odin] is just a pure space teleportation device. However, the energy of its space transfer still collided with Yubel, who was also undergoing space transfer. As a result of this "accident", Kobayashi Hayato, whom Yubel had finally managed to send away, actually appeared in the same world as her again!

—But it doesn't matter! Hayato Kobayashi wasn't teleported to the vicinity of Duel Academy. In such a vast world, there's no way he could find himself so quickly!
Although that's what he thought, Yubel, who was sent off from Earth after the KC Cup, was unaware of the "Dark Side of the Dimension" incident that occurred a year later, nor did he know how outrageous the power of "Prana," or "New-Type," was.

After all, even Amuro Ray, a New-Type, only felt that the abilities of "New-Type" were very strong before personally experiencing the miracle of Axis, but had no concept of how strong they were. Let alone Yubel, it is hard for a normal person to imagine that someone could sense a target from tens of kilometers away, and even sense emotions and even mental qualities.

Originally, relying on his status as an academy student who was an invincible enemy, he planned to find someone in the academy to stay with in order to quickly recover the energy he had consumed for the spatial transfer. However, after Jaden's "location" accurately found him back at Duel Academy, Hayato Kobayashi scared Yubel so much that he hid and dared not show himself.

After all, although Yubel could comfort herself with the idea that "she sent Kobayashi Hayato to another world where he couldn't interfere with her," in reality, she was completely suppressed by Hayato in her confrontation with him. Even if she faced Kobayashi Hayato again in her prime, she wouldn't dare say that her sneak attack teleportation technique would work again. Not being instantly killed would be a victory.

What's more, Yubel's injuries from the last transfer of Hayato haven't fully healed yet, while Hayato Kobayashi is in perfect condition. If I dare to show my face, I'm dead!

Even after Kobayashi Hayato went out to look for students in other dormitories after failing to find her, Yubel didn't dare to reappear openly. At the same time, she felt incredibly lucky that the extra power she had inadvertently used hadn't been wasted. She had initially included other student dormitories besides the main campus in her teleportation range because she wanted to completely sever Jaden's past relationships. Now, she had successfully diverted Kobayashi Hayato's attention, so it seemed that luck was on her side!
Moreover, Yubel was able to deceive Hayato because she relied on the help of Hayato's student, Amon Garlem, whom she had met back in the SAL underground research institute.

—During the initial spatial transfer, although Yubel did indeed only transfer the portion above a certain altitude without transferring the underground forest, thus wasting energy, Amon Garam somehow managed to reach the surface via underground ventilation ducts and was thus also sent to the Elf World.

Not only that, he also took away the nutrient solution rich in dueling energy that had been used to soak Yubel's body in the underground research institute. Yubel simply appeared beside him and started a deal with him. Without anyone else's help, Yubel, who possessed the ability to bewitch, easily stirred up the darkness in Amon's heart, using its power to help him hide and evade Hayato's search.

Although Yubel could sense a deeper darkness within the Duel Academy, considering that Hayato Kobayashi would not return for an unknown period after leaving, Yubel dared not be taken around by Amon. Instead, he possessed Amon's body, intending to consume the considerable darkness within him. At the same time, he began his own scheme, planning to use despair and fear to oppress the worst students in the academy and let Jaden witness the "darkness of Duel Academy."

Amon Garlem, who was possessed by Yubel, was also included in Yubel's Plan-B. His spy identity might make Jaden doubt his past relationships, and even if it was just a little bit, Yubel's goal would be achieved.

Yubel even has a Plan-C, because after she teleported away Hayato Kobayashi, she discovered that when Hayato Kobayashi dueled with her, a significant portion of his energy was attached to an invisible particle in the air due to the use of Synchro Summoning. With the power of the "Light Wave" intercepted in the past, Yubel deduced that by consuming the energy of this particle, she could actually reproduce Hayato Kobayashi's Synchro Summoning.

Yubel collected all the particles, but some were absorbed by Amon Garrum due to his presence. However, later, when Yubel forcibly awakened the spirit of his Duel Monster card "Lord of the Mist" and implanted it into Amon's body, controlling his duels to extract dueling energy, a large portion of those special particles were also collected by Yubel. A small portion was given to Professor Cobra, not to truly grant him great power, but merely for experimentation. The result of the experiment was that Professor Cobra's deck gained a few more "Reptile Fairy" cards; the Synchro Monster "Reptile Fairy - Melusin" was only so-so, not reaching the level of Hayato Kobayashi.

On the contrary, after possessing Amon Garam, Yubel discovered that although Amon himself could not perceive the existence of these particles, the remaining residue actually combined with the zombie virus that he originally intended to spread in the Duel Academy, and turned into an Undead deck with Synchro Summoning ability, which was the deck that Amon "switched" to use halfway through his duel with Jaden.

Yubel thought that even if the first two plans failed, he could still defeat Jaden and drag him to a secluded place to slowly train him, right? But Jaden actually managed to resonate with Amon Garlem's mind with that strange ability, and even broke his possession of him. Luckily, he managed to cut off the connection in time, leaving only an energy clone to absorb the damage from the battle, otherwise he would probably have been destroyed by Jaden there!
Even so, all of Yubel's energy was consumed while he was possessing Amon's body, and a large portion of it was lost. Even though the students of Duel Academy relied on the "Duel Energy Distributor" to recover their physical and mental strength and fight against the Duel Monsters that tried to approach the school, and the generated Duel Energy was received by Yubel through the "Death Gloves," in the end, they could only barely break even. Yubel's Duel Energy reserves were still almost depleted, and he was unable to heal his injuries and become a complete entity.

—But to say she gained nothing at all wouldn't be entirely true. She had squeezed out the final portion of those special particles from Amon Garlem's body and sent them to Yubel. She felt that if she continued to be so stingy with the energy within those particles, her progress in "conquering" Jaden wouldn't advance much even by the time Hayato Kobayashi returned. It was better to go all in and acquire a powerful force.

At the same time, Yubel also remembered to find herself a new body. This time, she figured it out—she absolutely couldn't find someone close to Jaden. It would be best if he didn't know her at all. Otherwise, who knows if Jaden would shout "bonds" or "friendship" and kill her again.

However, they can't be completely unfamiliar with each other, because Yubel simply can't stand not looking at Jaden all the time. If the possessed person has already met Jaden at least once, then it's normal to take a few extra glances at him when passing by Jaden, right?
Of course, the most important thing is to have enough darkness in one's heart. Although Yubel admits that he is very "love-struck" and his mind is full of Jaden's affairs, Kobayashi Hayato's existence is like the Sword of Damocles. No one knows when he will come back. Maybe he has already found clues to other student dormitories that Yubel himself does not know where he was teleported to after being away from school for half a day.

Therefore, it is necessary to quickly gather enough dueling energy, supplement it with the darkness in the possessed person's heart to heal and strengthen oneself, and at the same time, give up everything and use the energy of those special particles to exchange for enough power. The power of "evolution" contained in the power of "light wave" can also come in handy.

Yubel herself experienced the enhancement of that power. When she was sent to heaven, she only had the card 【Yubel】. It was under the power of this "Light of Evolution" that she acquired the second stage 【Yubel - The Hated Knight】 and the third stage 【Yubel - The Extremely Sad Dragon】. After receiving the power of the "Light Wave" that she chose to give up after being defeated, she gained the power of 【Yubel Phantom】 and other powers. Even cards such as 【Graveyard Creeper】 also gained enhanced forms such as 【Hell Graveyard Creeper】.

—Although in the end, it still couldn't beat Kobayashi Hayato's "Tears" deck. After all, the power of that deck was just too outrageous. Not to mention that it could even be combined with another deck called "Kusha". Kobayashi Hayato even claimed that the deck that was missing some "Opa Rei power" was not the complete version. It's so ridiculous, do you understand?
Without the useful body of Amon Garlem to assist her in moving around the academy, walking around the Duel Academy in her current energy form would be too conspicuous. After all, the academy's surveillance cameras weren't just for show, and she couldn't just casually jump around the school.

(He transforms into Professor Cobra's adopted son, jumping around at school, even with his bottom exposed.)

So, what are some ways to shift the school's vigilance to the outside, reduce the internal surveillance so as to seize opportunities, and at the same time, stimulate students' emotions as much as possible to spread the darkness in their hearts so that they can find a suitable new host?

Oh, there really is!
Although Yubel wouldn't be bold enough to openly appear in front of Jaden and the others again, even though she could easily defeat them in the human world, in the spirit world, because Jaden and the others' Duel Monsters can also materialize, although she still has a great advantage, Jaden and the others have also gained the ability to fight back. Conflict would only be a waste of her energy reserves.

However, there are countless Pokémon in this desert that can be manipulated and incited by oneself. As long as a certain number of Duel Monsters, which are much stronger than the Pokémon currently besieging the Duel Academy, can be gathered, even Jaden and his friends will have to devote all their energy to defending against attacks and protecting those troublesome so-called "friends". This will give one the opportunity to absorb the dueling energy from high-intensity duels while searching for people with enough darkness in their hearts.

Even the crisis of "monster siege" can spread fear and despair among students and stimulate the growth of darkness in people's hearts - it is simply a flawless plan!

Yubel, full of confidence, left the dark corner where he was hiding. He furtively looked around to make sure no one was passing by, and then used his energy body to pass through the ventilation duct of the Duel Academy. Although the ventilation duct of the Duel Academy was designed to be very narrow and not suitable for people to climb through like in movies and TV shows, what could Yubel do when all he had materialized was a hand and the rest was energy?
Leaving the Duel Academy, Yubel's feet touched the sand. He turned back and looked at the academy, muttering to himself, "Although I could efficiently absorb the dueling energy provided by the 'Death Gauntlet' and occasionally see Jaden, I was just a caged bird, a fish in a net, trapped inside. Now, having left, I'm like a fish entering the sea, a bird soaring to the sky, no longer bound by any constraints! Hahahaha!"

Spreading her wings, Yubel flew rapidly across the desert, preparing to execute her plan. (End of Chapter)
