Decade was surrounded by half a dozen villains. The Quirks of this group of villains either had close-range types or heteromorphic Quirks. Those with mutations wielded weapons. The villains that circled Decade were surprised by his transformation. There was a certain aura that the group couldn't explain. The kid wasn't a Pro but he was more serious about fighting. Little did they know, he already had experience in fighting against real villains.
One of the villains quickly dashed at Decade when he showed his back. Decade turned around and swung the Ride Booker through his chest, sparks flying from the attack. He slashed him once more before kicking him in the stomach.
"It's just one kid. We can take him!" a villain shouted. The other villains who waited for an opening attacked.
The Kamen Rider wasn't going to be in the middle and be attacked from multiple directions at once. He charged forth and swung his sword through a villain. Another villain tried to strike him from the side with a machete. Decade turned and slashed through him with ease.
Two of the villains rushed at Decade but he swiftly dodged and blocked their attacks as they ran through him. Decade transformed the Ride Booker into his gun form and blasted the two as they turned around.
The final villain left standing got a good punch on him, or should I say two. The villain was muscular with a pair of extra arms. The force of two powerful punches launched Decade across the fiery street and dropped the Ride Booker. The villain jumped in the air and dived towards Decade. The Kamen Rider dodged the attack and recalled the weapon to his right hand while using his other to summon a card and use it.
[AttackRide: Blast]
Decade shot up the last standing with a wall of bullets. However, they didn't seem to make him flinch. He smirked and shouted, "I'm bulletproof, kid!"
The Kamen Rider pulled out another card and inserted it into his belt.
[AttackRide: Illusion]
Two clones of Decade appeared next to him. The villain looked confused. The main Decade opened fire at the large villain as the two clones charged forward. The villain covered his face as one of the bullets hit his eye. The two clones attack him from multiple angles.
The villain has a hard time hitting one of them as they dodged his attacks. When one attacked, the villain focused his attention on swinging at the clone, who easily dodged the attack. This allowed the other to attack and the cycle repeats. The real Decade inserted his Final AttackRide card into his belt.
[Final AttackRide: D-D-D-Decade]
A trail of cards appeared in front of Decade and he jumped in the air. The cards followed him into the air. Decade flew into the card, each a portal to the back of the next one. The trail of cards led to the villain, who was busy attacking his clones. However, once the clones disappeared, the villain saw a large portrait of Decade doing a dive kick before the real Decade flew through it and kicked him in the head.
As the villain falls incapacitated, more come in from down the street. This group seemingly had a few more low-tier villains but one large villain caught his attention. They both had a bull-head stood at 8ft (243cm).
"Should've expected them to have a full cavalry," Decade commented. The Kamen Rider pulled out a card and inserted it into the Decadriver.
[Kamen Ride: OOO]
Multi-colored medals fly around Decade as a red, yellow, and green medals stop in front of Decade.
[Hawk! Tiger! Hopper!]
The medals then slam into Decade, transforming into Kamen Rider OOO.
[TaToBa! TaToBa!]
Kamen Rider OOO wore a primarily black suit with multi-colored lines going on different body sections. His helmet had a red hawk-shaped mold on the face. The eyes on the helmet were green. The arms were yellow with a pair of folded claws while the legs and lower torso were green. The center chest piece was a circle divided into three parts to match the corresponding armor section. The very top was a red hawk, the center was a tiger and the bottom was a grasshopper.
OOO counted seven of them, including the bull-headed villains. The villains tried to circle him. One tried to punch him with a rock-covered fist but he caught it and used the momentum to throw him down. A more feral-like villain tried to pounce on OOO but he swiftly turned and roundhoused kicked him.
A villain with a shotgun arm blasted OOO in the chest. His armor managed to protect him but the force of the blast knocked him up and the claws folded out. He cut through two villains. A villain wielding a machete tried to hack OOO but he caught the machete in between the claws of his left hand and twisted it so he let go. OOO then jabbed the claws into him, sparks flying at the point of contact.
"Dammit! I thought we were dealing with kids!" the shotgun-armed villain shouted. As he aimed his amr at OOO, Ojiro jumped in and whacked the guy away.
OOO glanced at the tailed martial artist. The bull-headed villain tried to strike at him. He exclaimed, "Ojiro!"
With a glance, Ojiro managed to dodge the attack by jumping back.
"It's you, right, Kimura?" Ojiro asked.
OOO nodded and said, "Yeah, it's me. Let's get rid of them."
Ojiro nodded as the two heroes-in-training got in a readied stance. The bull-headed villain laughed and said, "I expected this to be an easy job. While our contractors deal with All Might, we deal with the small fry and I can see that you're anything but small fry!"
The two remained silent as the bull villain smirked. They charged in at the same time, with Ojiro using his tail to get ahead quickly. He was smacked out of the air by the bull villain. As for OOO, he tried to slash at the villain's leg but he was kicked in the stomach.
The tailed martial artist gritted his teeth and circled the villain, moving at a fast pace while striking at multiple points. As for OOO, he jumped onto the back and grabbed the horns in an attempt to either steer him or make him trip by the sudden unbalance. Before he could do anything, the bull villain grabbed OOO by the wrist and threw him at Ojiro, knocking both fighters out of the way.
"Guy is tough to crack," Ojiro grunted. "Do you have a card or something to give us an edge?"
OOO already had a card in his hand and said, "Way ahead of you." He inserted the card into the belt and initiated the transformation sequence.
[FormRide: Shauta Combo]
Medals circled OOO before three medals of varying shades of blue slammed into him.
[Sha-Sha-Shauta, Sha-Sha-Shauta!]
OOO changed to a more aquatic-themed armor set. The helmet had yellow eyes with a blue fin on the top of the head. The middle section had navy blue outlines with a white pipe connected from the wrists to the shoulders. The legs were a layer of rubber-like armor with suction cups. As for the emblem, from top to bottom, the animals that are represented are an orca, eel, and octopus.
The Kamen Rider rushed towards the bull villain. He clenched his hands together and tried to hammer OOO to the ground. However, his body changed into liquid in a split second. The villain gritted his teeth before constantly punching the Kamen Rider's now liquid body. OOO circled the villain in a rapid flow of water. He solidified behind the bull villain and used the Denkiunagi Whips. They were small pipes that were connected to his shoulders and hands. The bull villain turned as OOO swung the Denkiunagi Whips. He blocked with his arms the attack but the whips left an excruciating sting on his arms.
"Bastard!" the bull villain shouted. Ojiro wasn't idle as he struck the villain on the back with his tail. The bull villain tried to smack Ojiro but he quickly dodged the attack. With his back facing him, OOO cracked the Denkiunagi Whips again.
The bull villain grunted at the sting from the whips. He turned around to smack OOO but his body liquefied. He propelled himself above the villain and solidified. The Denkiunagi Whips extended to wrap around the villain and sent an electrical shock at him. Ojiro took a moment to jump high in the air and spin around multiple times to build momentum. OOO let go of the villain to allow Ojiro to strike him hard across the face, knocking him out.
"Think we cleared this area?"Ojiro asked as he panted. OOO transformed out of the Shauta Combo and into his base form.
"Hey, I see them! They're down the street!" a villain shouted.
"I guess not!" Decade exclaimed as he inserted a card into his belt.
[AttackRide: Machine Decader]
A motorcycle materialized next to Decade. It was white with a magenta stripe at the front. It had bars that resembled Decade's on the front and back. Decade got on the motorcycle and patted Ojiro to sit next to him.
"Come on, it's not worth fighting the small fry!" Decade shouted. Ojiro nodded before getting on the motorcycle. The Kamen Rider drove off in the Decader and escaped the villains' line of sight.
"Where did you get the motorcycle?" Ojiro asked.
"I don't know where it came all. I only know that I have it, and can use it," Decade explained. He spotted the exit, which was as wide as the street that crosses into it. "Alright, let's get out of this fiery joint!"
Before Decade could escape with Ojiro, a large pool of fire appeared in front of them. Decade drifted to a stop. Fire began to erupt around them, Decade quickly turned the motorcycle around and drove off. The fires around them grow more intense as more suddenly appear in front of them. Decade managed to maneuver through the burning streets of this facility.
"It looks like they have control over the fire!" Ojiro pointed out.
"Great, but where is it coming from?" Decade asked. As Decade watched the road, Ojiro noticed a suspended building above the dome. It was the observation deck, the room
"Up there!" Ojiro pointed it. Decade looked up as he stopped the Decader. "It's too far up. How are we supposed to make it?"
"I think I have something!" Decade said as he pulled out a card. "But first we need to get out of here!"
Decade inserted the card into the belt.
[AttackRide: Invisible]
Decade, his motorcycle, and Ojiro turned invisible. The fires die down once they disappear.
The two of them found temporary refuge inside a warehouse. Ojiro sat down against some crates, taking the opportunity to rest while he could. As for Decade, he's leaning on a column.
"I wonder if anyone else is in this dome," Ojiro said.
"We'd most likely have run into them," Decade said. "We'd covered a good amount of area before finding a safe spot away from the villains. We'll probably find the others when we leave but we should be prepared to face off more villains."
"Still, we need to get out of here before any of that and we can't do that if they're watching the exits from the control room above," Ojiro said. He then asked, "You said you had a plan?"
"Not a plan but I do have something to help us get up," Decade said as he inserted the card into his belt.
[Kamen Ride: Agito]
In a bright flash of light, Decade transformed into Kamen Rider Agito. His armor was similar to Kuuga's except it was golden. It had its differences. For one, the chest piece had a black gem in the center with silver sides on the hips. The shoulder pads were black with a silver pointed outline. The crown on his helmet had higher peaks. Agito materialized another card and inserted it into the belt.
[AttackRide: Machine Tornador]
Decade's bike transformed into a different model with new colors. It was red with a golden secondary color. It transformed into a very extended hoverboard.
"Wait, a hoverboard?" Ojiro asked. With a lot of concern, he said, "Do you know how to use it?"
"I used it maybe twice or thrice. I can safely say that I can at least get up that high," Agito said. Ojiro gulped because it looked like he was going to need to hold on for his life.
Outside, a few villains approached the warehouse through its front doors. It was the group that attacked the Kamen Rider and Ojiro from earlier.
"They're here. I smell the exhaust of their bike!" a feral villain shouted. The shotgun-armed villain cocked the gun once more.
The bull villain stepped forward. He shouted, "I'm going to tear those punks ap-!"
Agito flew out of the warehouse, ramming the doors open. Ojiro held onto his shoulders and his tail wrapped around the Tornador. The gilded Kamen Rider rammed into the bull villain's head and knocked him down. His body crushed an unfortunate two who stood behind
Agito flew towards the control room and crashed through the window. He made a hard turn to stop the hoverboard. The Kamen Rider immediately jumped down to start fighting the few villains in the room. Ojiro soon jumped down and joined the fight. Agito was similar to Kuuga in terms of fighting style
The Kamen Rider dodged an attack from a villain with an ax hand. He grabbed his arm and threw him on the ground, knocking him out with a punch to the head. Ojiro managed to watch Agito's back by drop-kicking a villain who tried to attack him from behind. Agito turned his attention to another villain
"Alright, the area is secured," Agito said as he approached the control panel. "Let's see…"
"Wait," Ojiro said. "Maybe we don't need to escape through the entrance."
Agito turns around to see Ojiro pointing at the ceiling. There was an emergency hatch up there.
"Good eye. Less fighting the better. I could only fight for so long," Agito said.
"What's your limit?"
"Two hours. However, every transformation and weapon I summon, how much power I can use can decrease it," Agito said.
"I see," Ojiro nodded.
Agito turned around to decrease the fire around the dome. He said, "If someone is still somehow around the dome, hopefully they can get out easily."
Using the Tornador, Agito, and Ojiro reached the hatch and exited the fire dome. At the side of the hatch was a staircase that led to a ladder once it reached the steeper parts of the dome.
"This place is probably still crawling with villains," Agito said.
"We should prioritize finding the other students around this facility," Ojiro said. Agito nodded. The two of them saw a surge of electricity coming from the mountainous area next to them. "I think I have an idea how that is."
"Same here," Agito said as he hopped on the Tornador.
Agito flew the hoverboard towards the mountainous area of USJ. There he sees Yaoyorosu and Jirou at one end and a masked villain holding Kaminari hostage. Agito pulled out a card and inserted it into the Decadriver.
"Hold on tight!" Agito shouted as he pushed the buckle.
[Final AttackRide: A-A-A-Agito!]
The horns on Agito's helmet popped out smaller horns to the side. He quickly turned around before turning by once again. The Tornador was flying fast towards the villain holding onto Kaminar. Agito was flying from the side. Once he got close enough, Agito jumped off the Tornador and flung himself at high speed. He extended his leg out and kicked the villain holding onto Kaminari. Yaoyorozu and Jirou gasped as Agito seemingly appeared out of nowhere. The villain that Agito kicked was launched to the side of the mountain as he let go of Kaminari.
Once he landed, Agito shifted back into Decade. The Tornador managed to catch up and Ojiro jumped off just in time before it dematerialized. Kaminari wandered around giving a constant thumbs up with a derby face. He kept saying, "Yeah, yeah, yeah" on repeat. Jirou tried to hold back her laugh.
"I'm glad to see the two of you are okay," Yaoyorozu said.
"Likewise," Decade nodded. He looked around and commented on the scene in front of him, "Looks like you guys managed to hold your ground."
"Kaminari managed to take out most of them," Yaoyorozu said. The group looked at the braindead Kaminari walking around while pushing a thumbs up.
Jirou snickered as she tried to hold back laughing. She said, "He fried his brain in the process."
The ground shook as a large explosion was heard from a distance. Decade and the others turned to see a large hole in the ceiling of the dome.
"What was that?!" Ojiro shouted.
Yaoyorozu created a pair of binoculars to observe the entrance. She could tell by the trajectory of the hole that it came from around the entrance. She spotted All Might.
"It's All Might!" Yaoyorozu proclaimed. She noticed that he was posed as if he delivered a powerful. With what just happened, she dug ed out what happened. "It looks like he won a fight."
"That explains the large hole in the dome," Decade commented. This was the first time he felt All Might's true strength in person. The shockwave from the attack cemented his No. 1 position.
"Are the other teachers here?" Ojiro asked.
"It's just All Might. I'm sure the other teachers will soon arrive," Yaoyorozu said.
"I hope so. There's still probably plenty of villains out there," Jirou said.
"Yeah, yeah," Kaminari kept repeating the words with that same derpy expression. Jirou looked away as a way to avoid bursting out laughing. Suddenly they hear groans from the villains, finally recovering from Kaminari's attack.
"Dammit! Looks like they're still kicking," Jirou said. As the villains got up, a few bullets hit their shoulders. The students turned their heads in the direction of the bullets, which came from the entrance.
"That shot, it must've been the work of Snipe," Yaoyorozu said.
"Dammit, the pros are here!" a villain panicked.
"Cut that chicken shit! Let's do our jobs and get rid of them!" another villain shouted. One or two villains decided to book it in the hopes of escaping the area. Meanwhile, the others approach the students, cornering them to the edge of the cliff.
"Looks like we'll have to hold our ground until the pros arrive," Decade said as the Ride Booker materialized in his hand. "Jirou, watch over Kaminari! Everyone else, we'll take on the villains head-on!"
Yaoyorozu nodded before creating a staff with her Quirk. Jirou wrapped her jack around Kaminari's neck and pulled him close to her as she focused on the villains ahead of them.
Decade, Yaoyorozu, and Ojiro managed to hold off the villains. Ojiro used his tail to get ahead of Yaoyorozu and Decade. He got behind the villains and fought three of them by himself. Thanks to being worn out by Kaminari's attack, the villains were sluggish as they needed time to recover. With quick strikers from both his feet and tail, Ojiro managed to defeat his opponents.
The Kamen Rider slashed through two villains with one swift move before stabbing the last one in the chest. The blade didn't stab through him but it left sparks upon contact and launched him back. Yaoyorozu managed to whack a villain in the face. She quickly turned around and jabbed the staff into the last villain. She swung it upwards to hit his chin and launch him upwards.
"I think that's all of them," Yaoyorozu said. Decade turned to Yaoyorozu and nodded.
A mole villain popped out of the ground behind Yaoyorozu. As she turned around, the claws were already aimed at her face. The Kamen Rider was quick enough to blast him in the face with the Ride Booker.
"Okay, now I think that's all of them," Decade said before sighing.
"There's that pink bastard that kicked out asses!" a villain shouted. The group looked up to see another group of villains, this time they were the ones from the fire dome.
"Pink?" Jirou asked.
"It's magenta!" Decade snapped.
"How did they find us so quickly!?" Ojiro questioned.
"We were ordered to camp outside at all exits to ambush you! But clearly, you managed to escape so easily!" a villain answered.
"We saw something fly out of the top of some and decided to follow it!" another added.
"That won't be necessary!" a voice shouted. From the cliffs behind the students, Ectoplasm jumped up. He was a teacher and a Pro Hero at U.A. He wore a black-domed helmet with a large trench coat. Jumping with him were his clones. They landed in front of and next to the students.
"Stand back!" Ectoplasm ordered. The remaining villains charged at Ectoplasm and his clones. The Pro Hero and his clones managed to smack down the villains with quick, precise kicks. The fight was over in seconds.
"Thanks for the save," Ojiro said. "I was starting to get exhausted."
"Go make your way to the entrance. It's so far the only secured place in this facility," Ectoplasm said. "I'll survey the area and make sure that this area is secured.
"Yes, sir," Decade and the others said.
Decade sighed as he undid his transformation. He balances for a second before recovering. He stood up with a little lean.
"Are you okay?" Yaoyorozu asked.
"I'm fine. Just feeling a little fatigued. I can only transform and use my powers for so long without feeling tired," Kimura said.
"Need any help?" Ojiro asked.
"I'll be fine."
As Kimura and the others leave the scene, a man wearing glasses with a light brown hat and coat watches from a distance. He said, "Curse you, Decade! Your powers couldn't die off with you. I guess we'll see if this one can put good use to your powers."
A portal materialized behind the man as he turned around to walk into it.
Author's Corner
In an attempt to avoid writing just the plot of My Hero Academia, I decided to have Kazuhiro teleported to one of the various spots in USJ. Relatively speaking, the whole incident probably lasted around an hour to an hour thirty, so that's why it's hyper-condensed into one chapter. Again, this series is based on Kazuhiro's perspective so I did cut off a lot of the important tidbits and fluff. I was thinking of adding one more chapter to include more fights again, looking at how long the actual USJ incident lasted, it probably wouldn't make sense timeline-wise.
Anyways, the next chapter will be the epilogue of USJ and set-up for the next major MHA arc.
Response Corner:
Guest (from chapter 5): Again, have to use a translator so sorry if it comes out wrong or if I misunderstood your point. I do want to write more stories with Kamen Rider and My Hero Academia, it's just that I'm not sure if I want to write more Kamen Rider x MHA stories. There are already other writers out there who already do these stories where both exist in the universe.
An0therName (from chapter 1): I wanted to write a story about how a mundane person gets roped onto a big adventure in another world. I thought it would be an interesting angle if Kazuhiro/Decade was an outsider to both the various worlds of Kamen Rider and the world of My Hero Academia. Besides, most seasons of Kamen Rider, even anniversary ones, aren't familiar with pre-existing Kamen Riders since they're not common knowledge. Like in Fourze, Kamen Riders were just urban myths and legends.
XenonKirito (from chapter 6): I decided to make the Rider Machines as AtttackRide cards. I mainly did it because Decade used an AttackRide card to transform his bike into Kaixa's bike. Also, don't forget that the powers and abilities of the 23 Kamen Riders (Kuuga to Revice) also extend to their equipment, so anything that's part of their kit is at Decade's disposal.
