When Youyu returned to Domino from Kaiba's space station, little Judai had already been taken to the hospital by everyone.
Fortunately, after the doctor's examination, he was found to be very healthy with no problems whatsoever; just to be on the safe side, he needed to stay for a little observation.
By the time Youyu arrived at the ward, little Judai had long since recovered his energy, bouncing around the room with seemingly endless vitality, not looking like someone who had just fainted.
Chinai was holding his hand, scolding him: "From now on, when you go out, you can't run around everywhere, understand?"
"But I wanted to go to the bathroom..."
"You still have to tell me." Chinai said, "If you want to use the bathroom, I'll take you, but you can't run off by yourself without saying a word."
When Judai went missing, possibly no one was more anxious than Chinai; she felt truly like she had lost her own child.
Luckily, in the end, nothing went wrong. It was Jonouchi, who came along with Yugi, who found unconscious Judai on the second floor.
Judai tilted his head: "But... Youyu Sensei said, sister Chinai once got lost on her way home from school..."
Chinai: "..."
Because it's indeed a fact, she really had no way to argue...
"The point is, you can't run around by yourself anymore. That way, everyone will be worried about you, understand?"
"...Oh." Judai said softly, "I'm sorry, sister."
Seeing little Jellyfish behaving so obediently, Chinai didn't say much more, just gently rubbed his head.
Judai was the first to notice Youyu who pushed the door open, his eyes lit up as he jumped off the bed: "Youyu Sensei!"
He exclaimed as he rushed to Youyu.
After confirming little Judai was okay, Youyu then asked about the specific situation. He quickly got the gist, it seemed that Judai had gone out looking for the bathroom without telling anyone and somehow was found passed out upstairs.
Interestingly, after everyone realized Judai was missing, they split up to search, and during the search, Chinai got lost...
Upon hearing this, Youyu couldn't help but glance at Chinai. By now, Chinai had covered her face and turned her little head aside, as if saying—
—So embarrassing, don't look QAQ...
Youyu let out a slight breath. Considering Chinai was probably very upset when Judai was missing, he didn't say much, just patted her on the shoulder for comfort.
Being a road idiot... is also something that can't be helped.
Youyu thought of the curious anecdotes he had seen long ago.
Someone had discovered a dead whale on the coast of East Yorkshire, England, completely without injury on its body, but it was astonishingly a full eight hundred meters away from the nearest coastline.
It was speculated that it had become stranded on the coast and wanted to roll back into the sea, unfortunately, its sense of direction was so bad it rolled in the wrong direction...
This incident was enough to show that being a road idiot is not an individual problem.
Like the White Dragon girl who is such a strong spirit, isn't she also a road idiot?
Judai has narrated the sequence of events more than once to everyone. But even now, he still couldn't say clearly how exactly he had fainted, or what he had experienced during the time.
"I remember, I seemed to have met a big brother." Judai struggled to recall.
"Big brother?" This caught Youyu's attention, "What kind of person?"
"Well... dressed like Mr. Yugi, kind of dark, and... oh right, he had a strange square thing. He wouldn't let me touch it, said it was given to him by a very important person..."
Judai scrunched his eyebrows together in effort, struggled to recall for a long time, but finally, scratched his head and chose to give up: "Ah, can't remember. I don't remember what happened next."
But this had already provided Youyu with quite a bit of information.
This description sounded like... Aigami?
What did Aigami want with my student?
Judai seemed to remember nothing, but Youyu felt there must be someone who knew what exactly happened.
Someone who was with Judai constantly, playing the role of a close bodyguard.
"You guys stay here for a while." Youyu stood up, said, "Watch over Judai. I'll go ask the doctor about his situation, and give his parents a call to inform them."
However, after exiting the room, he didn't do what he had said, but instead avoided detection, found an empty storeroom, and slipped inside.
Closing the door behind him, Youyu calmly spoke to the empty room, "Alright, I know you're here. There's no one else now, we can talk."
Wide black wings unfolded from the shadows, beautiful heterochromatic pupils lit up from the darkness. Yubel emerged, arms crossed.
"What happened?" he asked.
"You've already heard from Judai." Yubel replied.
"Not everything." Youyu paused, asked, "The person Judai mentioned... did you defeat him to protect Judai?"
Yubel remained silent, but his expression turned a bit nuanced.
"Wait, it wasn't you?"
This caught Youyu a bit off guard.
He was sure that the person Judai encountered was Aigami. If Aigami targeted Judai—whether trying to erase his memory or kick him out of this dimension—Yubel definitely wouldn't sit idly by.
But Judai was still here, neither disappearing to the Other Dimension nor losing his memory of Aigami.
If it wasn't Yubel who drove off Aigami, then who could it be?
Can't be...
Youyu's gaze shifted as he thought of something: "Did Judai defeat his opponent himself? Or perhaps... the other guy hiding in his heart?"
This time it was Yubel's turn to be shocked: "How did you... how much do you actually know?"
"Enough." Youyu frowned and asked, "But how could this happen? Did his alternate personality awaken?"
"...No."
Yubel didn't pursue why Youyu knew so many details for now, but she became even more curious about Youyu.
Youyu held many secrets, a man she couldn't figure out no matter what—in this world, such people were rare.
She had considered more than once sneaking in while Youyu was sleeping, tying him up to thoroughly research him... but unfortunately, she couldn't beat him.
"Judai's dormant personality, we call 'The Supreme King.' He shouldn't have awakened so soon." Yubel said, "It's far from the time, and there hasn't been an opportunity."
"Then why...?"
"I don't know either." Yubel was somewhat agitated, "Perhaps it's because of that boy's influence. He has a strange cube that can affect people's consciousness, touching things hidden deep in your mind. I think that thing disturbed the sleeping Supreme King."
Damn, Aigami can't handle his cards nor accomplish things, and now he's causing trouble. Youyu thought to himself.
But since Aigami so unfortunately provoked The Supreme King—one of the people he should least provoke on this planet, isn't it then...
"That boy, is he still alive?" Youyu asked.
Playing cards with The Supreme King and losing would mean not even ashes remain, right?
"He hasn't." Yubel grumbled, "The Supreme King's power wasn't fully awakened, and he immediately returned to sleep after the duel. That guy must be seriously injured, but at least he saved his life."
Yubel said this as her mismatched eyes narrowed.
"But he's a potential threat." she said, "That guy sensed the presence of The Supreme King, knowing the hidden potential within Judai. And he isn't an ordinary human either; he has some... extraordinary powers I can't understand.
He might return, maybe he has other powerful allies. Perhaps they already have their sights on Judai..."
"Don't worry," Youyu said calmly, "I'll handle it."
Yubel's eyes flicked: "Do you have any leads? Do you know who they are?"
"Sort of."
Initially, Aigami and their goal was merely to stop the president from grave-digging attempts to ascend; it wasn't an evil plan, nor did it have dreadful consequences. As long as their Plana didn't try anything crazy and honestly ascended, Youyu didn't intend to trouble Aigami.
But now, this guy actually dared to touch his beloved student.
Then Aigami was finished.
...
Kaiba Group Headquarters.
"Brother!" Mokuba said, "The results of the first batch of equipment tests used against Aigami have no issues whatsoever, and theoretically should yield great results.
Moreover, the new generation of Duel Discs is also equipped with the 'Anti-Dimensional Duel' system. With this new system, Aigami can't use his abilities to overwrite the rules and enforce a 'Dimensional Duel' anymore!"
"Hmph, very good." Kaiba folded his arms, thought for a moment, and said, "Notify Youyu to come and pick up a new model Duel Disc. He might need it soon."
"Alright, brother!"
Mokuba immediately went to the side to make a phone call.
He knew Youyu liked Duel Discs the most; he'd definitely be delighted to hear this news.
Kaiba turned back, his gaze swept silently over the agents behind him. Behind him was a group of highly trained agents, all armed and equipped with blue exoskeleton armor from head to toe, the visor area of their helmets glowing with a dark red light.
An entire squad of Kaiba Group's most elite agents, fitted with a full set of "Anti-Aigami Armaments," unaffected by Aigami's strange dimensional abilities.
They were all ready and waiting. Now, just waiting for the computer to give Aigami's location, they would immediately deploy like sniffer dogs catching a whiff of prey, precisely targeting and capturing the opponent.
"Aigami." Kaiba's gaze was icy, "You're finished."
...
"Cough, cough!"
Meanwhile, Aigami, both remembered by Youyu and Kaiba and about to face impending doom, was at this moment sitting in a corner in Domino, leaning against a wall, coughing up a mouthful of fresh blood.
Dimensional Duel lost. Although he managed to escape, his injuries were quite severe.
He felt a bit exhausted now, his legs not following his commands, and the Quantum Cube had been overused too, making it hard to concentrate momentarily.
He leaned against the cold corner, breathing heavily.
"Damn it. That Horn Imp... what exactly is he?"
