Yuto groaned as he woke up, his head feeling heavy. He didn't even remember falling asleep. The last thing he remembered was being on the docks with shipping containers… He had been with Shun, but they'd split up to check out some sounds… and then he felt something prick the back of his neck… and then nothing.

Yuto did his best to open his eyes, but it was so hard. His eyelids felt as though they weighed a ton. As he struggled to open his eyes, he heard a few voices speak.

"Oh, it looks like our very important prisoner is awake!"

"Let's let the Professor know!"

"Professor, he's awake!"

"Good." As Yuto managed to open his eyes, he saw where he was. He appeared to be in some kind of dungeon. There was a TV screen on the wall in front of him showing the face of the Professor, and a camera above it pointed at the XYZ rebel. There were five Fusion soldiers around him. Yuto then noticed that he was sitting in some kind of chair, his arms locked above his head and his feet trapped in some stocks.

His next realization was that he was wearing only his pants. The rest of his clothes and shoes had been removed. The eggplant-haired rebel tried to ignore that fact, but he could feel his face heating up.

"So, we've finally captured you, Yuto," the Professor sneered. "You've been causing us quite a bit of trouble haven't you? But now we've finally caught you! Now, normally I'd have you carded, but given all the trouble you've caused us, I think a different punishment is in order!" He looked at the soldiers. "Show him no mercy."

"Yes, Professor!" the soldiers replied. The TV screen turned off, and the soldiers got closer to Yuto. The XYZ duelist was still being affected by whatever had put him to sleep, unable to even try to get away as they reached for him. Then he felt their hands tickling him, and he gasped and started giggling.

"Heeheeheeheeheehee! Nohohohoho!" he giggled helplessly. He could feel the soldiers tickling his feet, stomach, sides and ribs. The whatever-it-was that had put him to sleep seemed to have made him less sensitive for the moment, or maybe that was just because he was still groggy. At least the soldiers weren't tickling his armpits yet. That was his death spot.

The soldiers smirked. To think that Yuto, the biggest thorn in Academia's side, could be brought down with a sleep dart and a little bit of tickling! Of course, it wasn't going to be just a little bit. No, after all the trouble Yuto had caused Academia, he was going to be truly punished. He was going to be Academia's tickle slave forever!

The ticklish stimulation seemed to be causing the sleep dart's effects to wear off rapidly, and Yuto squealed as his sensitivity increased. "NOHOHOHOHO! STOHOHOHOHOHOP! NOHOHOT TIHIHIHICKLIHIHIHING! ANYHYHYTHING BUT THAHAHAHAHAT!"

Being tickled was probably Yuto's biggest weakness. He couldn't handle it for more than a few seconds without breaking down and begging for mercy. But he knew he had to resist. He had to! At least long enough for his comrades to find and rescue him. He knew Shun would notice he was missing, and would certainly be looking for him. All Yuto had to do was endure this until his friend found him.

"His skin is so soft!" one of the soldiers observed. "It's like a baby's!"

"Maybe that's why he seems to be so sensitive," chuckled another.

Yuto thrashed around, trying to break free from his restraints as one of the soldiers dragged their finger up his ribs. For the first time in his life he regretted having such a strict skincare routine. He always made sure to apply cocoa butter baby lotion to every inch of his skin after every bath or shower, and his skin was as soft as a newborn's as a result. Unfortunately, it was also as sensitive as a newborn's as well, something that had finally come back to bite Yuto in the ass.

"EEHEEHEEHEEHEEHEEHEEHEE! NOHOHOHOHO! PLEHEHEHEHEHEASE! NOHOHOHOT THEHEHEHERE!" Yuto screamed with laughter as one of the soldiers started tickling his armpits. "AHAHAHAHANYWHEHEHEHEHERE BUT THEHEHEHEHERE! PLEHEHEHEHEHEASE!"

"Oho ho! looks like I found his death spot first!" the soldier chuckled. "You guys all owe me 15,000 yen!"

"Aw, I was hoping to win the bet…" pouted one of the others.

Yuto desperately pulled on his arm restraint, trying in vain to free his arms and hide his poor armpits. The soldier tickling them had devilishly long nails, and they were driving the poor rebel crazy. "NOHOHO! NONO! STOHOHOHOP! MERHERHERHERCYHYHYHY! MERCYHYHYHYHY! STOHOHOHOP!"

It was embarrassing how quickly Yuto had begun begging for mercy, but he really couldn't take all the tickling, especially with his armpits being tickled. On a scale of 1 to 100, 1 being not ticklish at all and 100 being I will die if you touch me, Yuto was off the charts. His ticklishness was at 150, with 150 being I will die if you even wiggle your fingers at me without touching me, for most of his body (he blamed his skincare routine). But his armpits were his death spot, and definitely closer to a 200, with 200 being I can't even think straight if you wiggle your fingers at my death spot without touching me.

The soldiers definitely knew how to torture a prisoner. Yuto could barely breathe from how hard he was laughing. He began to feel dizzy from the lack of air, and slowly his vision went dark…

A sharp smell filled Yuto's nose, and he jerked wide awake. One of the soldiers was holding something in front of the rebel's face. "Ah-ah-ah! No sleeping for you! These smelling salts should keep you wide awake and alert for your punishment!"

"No… Nonono! No more! Please no more!" Yuto pleaded, eyes wide with horror. He now realized exactly what the Professor meant when he told the soldiers to show him no mercy. He wouldn't even be able to find relief in passing out. The soldiers would just wake him up again.

The rebel let out a cry of despair as the soldiers began tickling him again. "NOHOHOHOHOHOHO! HEHEHEHEHEHEHELP! SHUHUHUHUHUHUHUN HEHEHEHEHEHELP! SAHAHAHAHAVE MEHEHEHEHEHE!"

Yuto was absolutely exhausted. He had no idea how long it had been since he had first awakened in his predicament. Every waking second was full of pure ticklish agony, and every time he passed out he was immediately awakened once again by those horrible smelling salts. His only knowledge of the passage of time was when the soldiers changed shifts.

They hadn't even fed the poor rebel or given him any water, and Yuto was absolutely starving and dehydrated. He didn't know how much longer he would last.

Suddenly the TV turned on, revealing the Professor. The soldiers immediately looked at the screen.

"How's our favorite prisoner?" the Professor asked. One of the soldiers grinned. "He's so sensitive!"

"It's so much fun torturing him!" said another soldier. A third added, "Yeah, but I don't think he's going to last much longer. He's definitely dehydrated and hungry. I don't think anyone's given him any food or water since he was captured."

"Well, it won't do for him to die of dehydration or starve to death," the Professor said. "That would just end his punishment way too soon. I'm authorizing one break from the torture. Feed him and give him some water. And clean him up too, but don't unlock him. A sponge bath will suffice."

"Yes, Professor!" the soldiers replied.

So, after what had to have been at least a few days, Yuto was finally fed and given some water. He didn't really want to eat or drink anything that the Fusion minions gave him, but he was too hungry and thirsty to exercise any self-control.

After the soldiers fed and watered Yuto, they began giving him a sponge bath. One of them started cutting off the rebel's pants so they could wash him properly. But Yuto was too exhausted to care at this point. His eyes slowly closed…

The sound of yelling roused Yuto from his sleep a bit. A familiar voice reached his ears, "WHAT THE HELL DID YOU DO TO HIM?!" Another, less familiar voice responded, "We just tickled him, I swear!"

Yuto passed out again for a bit. A while later he woke up a little to something warm being wrapped around him. His eyes opened a little, and a blurry face was in front of his own. The familiar voice spoke again, this time gentle, "It's okay, Yuto! I've got you! Go back to sleep!"

He felt himself being lifted, and then he was out like a light again.

The next time Yuto woke up, he felt a lot better. His eyes fluttered open, and he saw Shun leaning over him. "How are you feeling?"

"…Like a towel that's been wrung out…?" Yuto's voice was hoarse from all the laughing and screaming he'd been doing. Shun took his hand and gently squeezed. "I'm sorry it took so long for me to find you. Did those soldiers really not stop torturing you for three straight days? Not even when you passed out?"

Yuto shook his head. "They used smelling salts to wake me up every time… They wouldn't let me sleep, and the only time they gave me food and water was right before you came…"

Shun got a dark look on his face. "They deserved a fate worse than what they got…"

Yuto gently squeezed Shun's hand and sat up. Then he realized that he was wearing Shun's coat. It took the eggplant a moment to notice that Shun wasn't wearing it. "Uhm…?"

Shun understood immediately. "You were completely naked when I got there…" he explained, blushing a little. "I couldn't find your clothes, so I put my coat on you to cover you."

"Thank you," Yuto said.

Meanwhile back in Academia, a certain cabbage-haired duelist was watching the recorded footage of the eggplant rebel's torture, along with a few soldiers. One of the soldiers glanced at him.

"He looks a lot like you," the soldier said. "So… are you ticklish too?"

Yuri scoffed. "Of course not. And even if I was, nobody is stupid enough to find out! I'd card them on the spot, or feed them to Starve Venom."
