With Kane, Daisuke, and Nobu getting training from Mai. Things will be heating up. Also, Momo is holding the knowledge of the past, what shall she uncover from it? Let us see as the story begins.

Yaoyorozu Residence

After Momo went to the Library she took and purchased a mystery book home and once she came back she started checking the content from within.

Momo: Core Medals. 800 years prior to the early to mid 2000s, alchemists created medals as a means to create artificial life, drawing from characteristics of different animals. These formed creatures later dubbed Greeeds. Each Greeed had their tenth Core Medal Removed in order to create "desire" in the remaining 9. Each Core Medal set was separated by color and animal classification. Red Medals were birds, Yellow Medals were big cats, Green Medals were Insects, Silver Medals were heavy mammals, and Blue Medals were marine animals.

While she continued to read the book she heard a knock on the door and puts the book down and opens it to see a woman with brown hair who was wearing pink gear that looked like she was from space. This woman was the Pro Hero Uravity and with her was Deku, Charge Bolt, Pinky, Ingenium, and last but not least Dynamight.

Momo: Oh it's you Ochako, I assume your here to discuss Iida being attacked by one of those Armored Individuals?

Ochako: Yeah, Iida called me that I should come for this meeting.

Iida: Indeed my encounter with Baron was something that I never would expect.

Deku: It's okay Iida you did your best.

Dynamite: Yeah four eyes though it could have been worse.

Momo: I'm glad you're all here, I've found something interesting.....

Pinky: What is it Momo?

Momo: It will be easier if I show you inside.

Momo then lets them all in and then they all take a seat and Momo starts to divulge what she discovered.

Momo: That's as far as I got before all of you showed up.....

Deku: My word, that is, hard to believe......

Ochako: Wow....

Iida: Are you sure this is real?

Dynamite: It looks like it but still that is far before quirks.

Pinky: Yeah, though can't believe our world already has quirks of their own.

Momo: It's just a myth, but it goes even deeper than that. Apparently the medals were further divided into three groups. Head Medals, Torso Medals, and Leg Medals.

This intrigued the group which Ochako decided to ask more about the medals.

Ochako: What did the medals do when you use them?

Momo: In human hands they were mostly worthless, but if a significant number of Core Medals were removed from a Greeed, it would lose a considerable amount of its power.

Iida: I see though I have to ask Momo why are you interested in these Core Medals? I thought we were going to talk about the Armored Individuals, specifically Baron.

Momo had to agree with Iida, while interesting did not help them in the slightest. Momo flipped the page and her heart nearly stopped at what greeted her.

Momo: Oh my god....

When Momo looked at the page everyone was confused until she laid it on the table and everyone in the room were shocked and they all saw. There was an armored warrior with a red helmet themed after a Hawk, arms with folded up claws themed after a Tiger, and green legs themed after a Grasshopper. On his waist was a device that held 3 Core Medals and a circular device on his hip.

Dynamight: What the heck!

Pinky: Are we all seeing it?

Ochako just nodded at Pinky.

Chargebolt: Yeah I see it.

Deku: The warrior looks similar to...

Iida: Baron...

Momo picked the book back up before reading the next passage.

Momo: Despite the Greeeds being sealed by a greedy King's selfish desire to become a higher being. A lone drifter devoid of desire unknowingly set them free in modern day Japan. The Bird Greeed, Ankh sought the drifter out and gave him the seal, known as the OOO Driver. Using the Core Medals, the drifter became a warrior known as Kamen Rider OOO, who fought the Greeeds and stopped a crazed individual from destroying the earth.

When Momo finished she and the others looked at OOO and then remembered Kenji saying that Kamen Riders have been on Earth for a long time.

Momo: I think Baron and the other armored individuals are like OOO.

Pinky: I mean yeah both this OOO guy and Baron have similar belts.

Deku: Though different powers.

Ochako: This is freaky.

Dynamight: I'll say it almost like history is coming back to our time!

Iida: Indeed though that begs the question why are Baron those other Armored Individuals here?

Momo then noticed another strange statement that only made her even more concerned.

Momo: Apparently OOO was the 21st Kamen Rider overall, and the 12th Kamen Rider of the Heisei Generation of Riders.

Deku: Wait 21st Kamen Rider also 12th Kamen Rider of Heisei? I never heard of that before?

Pinky: Same.

Ochako: Me too though it must have been lost through time.

Iida: Momo, can you tell us more about OOO?

Dynamight: Yeah, I am now getting curious.

Momo: Apparently OOO was granted different powers based on what Medals he scanned in the Driver. This would also give him an altered appearance, the most powerful being the Full Combos, which includes his default form Tatoba.

Pinky: That sounds catchy. Tatoba, Tatoba, Tatoba.

Momo: You're not far off Mina, when a Full Combo was scanned it would chant the combo name as a musical tune played.

Ochako: Really? That is strange.

Iida: Actually, I heard music when Baron transformed plus an announcement.

Dynamight: So do all those Drivers have some music and announcement to it?

Deku: I mean that wouldn't be far off at what we just learned.

Chargebolt: Yeah, this is still freaky to me.

Momo: We'll from what I'm reading, it seems the other Full Combos gave OOO abilities similar to Quirks.

When Momo said that it caused Deku to pull out his notebook, Ochako snatched it.

Ochako: Oh no we are not having one of your analyst moments.

Deku: But Ochako this could really help us!

Ochako: No! We don't have a lot of room for your notebooks! We had to get a storage unit for them!

Momo: We'll only look at one to keep things simple, let's see Gatakiriba......oh my......

Pinky: What is it Momo.

Chargebolt: Yeah something the matter?

Dynamight: Come on spill it!

Iida: Hold on give her some time.

Momo: Gatakiriba, the Combo using all three Core Medals from Insect Greeed Uva. Also dubbed the Strongest Combo. The Kuwagata Horns on the helmet allow OOO to shoot lightning, good for handling multiple enemies at once. The arms give him access to the Kamakiriswords, arm-mounted blades that can deal devastating damage. The Batta legs allow this form to achieve the highest jumping height.

The group was floored with this information that Momo was reading and continued to look.

Deku: What else can this OOO do?

Chargebolt: Yeah, I mean he gots lightning.

Pinky: arm blades for weapons!

Ochako: And is able to jump really high!

Momo: Gatakiriba's signature ability is that it allows OOO to clone himself to numbers surpassing 20. This is to mimic Insects tendency to swarm to neutralize threats.

Dynamight: Man, this guy seems powerful!

Everyone agreed until Momo read another page which shocked her.

Momo: Uhhh, guys you might want to hear about the Core Medals.

Deku: What is it?

Deku asked Momo then read the page out loud.

Momo: Apparently using the Full Combos not Counting Tatoba is a rather dangerous act due to the severe strain it puts on the user's body. The Drifter was put into states of near-fatal exhaustion the first few times he used them.

Dynamight: Well damn that sucks.

Deku: And here I thought OOO was invincible. Just like quirk users, they all have weaknesses.

Momo: I'm more concerned he was willing to hurt himself so frequently, why put yourself through that?

Iida: Probably, because he was a hero...

When Iida said that everyone in the room was silent and contemplated that a man who didn't have powers until he became a Rider was willing to sacrifice himself to save the world.

Deku: The person was quirkless and was willing to go through that pain.

Ochako: I know I mean I can't imagine someone that selfless.

Charge: Same here.

Pinky: I have mad respect for OOO.

Dynamight: Tough bastard that is for sure.

Iida: So brave.

Momo: We might have to take this into consideration.......

Everyone was silent until they heard the door kick open and saw Kenji looking really angry.

Kenji: You, oh you just have to screw up my life even more than simply not letting me fix my dirt bike don't you?!

Froppy: Come on Kenji is not going to be that bad, ribbit.

Kenji: Not bad?! I'm a teenager and my sister is treating me like a child! I don't need a damn babysitter at my age!

Kenji then walks up to his room while Froppy sighed and then turned to Momo and the others.

Froppy: Sorry, he got mad after I told him, ribbit.

Momo: I knew he would get mad but not that bad. Go talk to him, he's angry with me not you.

Froppy: Will do though I have a feeling Kenji will try to ditch me, ribbit.

Momo: You know he can't escape you.

Froppy smiled and nodded and then headed towards Kenji's room.

Helheim

On Helheim Nobu, Daisuke, and Kane were seen in the forest in their rider forms each practicing on their own set by Mai.

Zangetsu was seen blocking and shooting targets as he ran through the forest. For Duke, he was seen hitting a dummy with his rapier. Finally, for Knuckle he was seen punching a giant rock.

While all three trained Mai and Kouta watched from afar.

Kouta: So far they are getting the basics of it but it will take time to reach Kenji fighting prowess.

Mai: Indeed but knowing the three of them their drive will make it happen.

Kouta nodded and both he and Mai continued to watch the three train. 2 hours have passed and all three of them were back in human form taking a break. So far they are drinking water and trying to regain their energy.

Nobu: Physical activity is not something I'm accustomed to........

Daisuke: You get used to it man I feel out of shape....

Kane: Fuck man my body feels sore.....

While the three continued to drink water Mai appears before them.

Mai: So how are you three with your training? Anything that needs to be clear about, or do you need something else to help you train better?

Nobu and Kane were okay while Daisuke placed his concerns.

Daisuke: Mai, I have a question why did you make me practice on a giant rock and not a dummy?

Mai: Oh that is because the dummies wouldn't last on you so a rock would be better. Plus so far it seems you got back some of your rhythm from punching the rock.

Daisuke: I mean yeah but wouldn't it be effective for me to you know not just punch a rock?

Daisuke said which Mai chuckled.

Mai: Daisuke the rock is just for you to get a feel for things. Though it seems that you are ready for the next part of your training.

Daisuke: And that is?

Mai: Oh you will be fighting Inves and possibly an Advance one.

When Mai said that, Daisuke paled a bit.

Daisuke: Me and my big mouth....

Mai: Don't worry Daisuke it won't be that bad besides with the training you have been doing you will be able to handle it. Now, it seems like you all are rested so now back to work you three.

All three groaned and then got back up and turned back into riders and then went back to their training.

Kenji's room

Inside Kenji's room, Kenji is seen lying on his bed angry which he then hears a knock on his door.

Kenji: Go away Momo! I'm not in the mood for your bullshit excuses!

Froppy: Oh come on Kenji I just want to talk, ribbit.

Kenji: Like hell, I'm going to listen to some damn explanation! I don't need someone babysitting me!

Kenji then ignores Froppy until he hears his door open and turns to see that Froppy used her tongue to open the door and then walks into his room.

Kenji: Fine, just invade my privacy. Not like I'm going to listen to what you have to say.

Froppy: Oh come on Kenji your sister worries for you. I mean she asked me to do this favor and I don't mind. Plus, I can understand where she is coming from. I mean I have a brother and sister so of course, I want to keep them safe.

Froppy said, which made Kenji mad at her.

Kenji: That's your brother and sister! Why do I have to be watched constantly?!

Froppy: It's only for a week so please calm down.

Kenji just looks at her and then sighs and turns his back towards Froppy.

Kenji: Whatever, it's not like I get a say in the matter.....

Froppy then leaves and closes the door.

Kenji: I don't need other people looking out for me, I can do it just fine on my own.

Living Room

When Froppy came back downstairs to the others in the living room she got up to speed by them about Kamen Rider OOO and the similarity to Baron and the other Armored Individuals.

Momo: So that's what we've learned, we still don't know how exactly this connects with the fruit-themed Riders we seem to be dealing with.

Froppy: I see well that mystery we will have to figure out.

Pinky: I know though with the history of Kamen Rider OOO you think Baron and his friends are here because of some threat?

Deku: I mean you are not off about it Mina. So far these guys only go after those people who ate the fruit that gives Quirks.

Dynamight: Actually, Baron said it they were called Inves.

Iida: Inves?

Chargebolt: Maybe that is what they call people who eat the fruit?

Ochako: Yeah, makes sense but why would these Inves be threats? I mean they're just people who can't control their quirks. I don't see why he needs to kill them

Dynamight: Maybe they know something we don't?

When Dynamight said that all of them started to think about why Baron and the other Armored Individuals attacked the Inves.

END

KLigers98: Seems like the heroes are going down the rabbit hole and started to think outside the box. Also, it sucks to be Kenji. He got a Pro Hero watching his ass. Though I will say it is not all bad since Kane, Daisuke, and Nobu are training though I feel in time they will finally be able to handle more threats. Anything to add Toja?

Tojamaru: It is a necessary precaution considering the most experienced fighter is now under heavy watch. The only thing that we can hope for is that the pro heroes consider a more diplomatic approach to the Armored Riders rather than assuming they're a threat. Things like this take time of course, so we can only hope for the best.

KLigers98: Agreed, now with that said thanks for reading My Hero Vigilantes: Return of the armored riders. Like, comment, and follow for more chapters. Ligers signing off.

Tojamaru: Until our paths cross again everyone!
