A/N: uh there are some manga spoilers but nothing too obvious. Also surprising no one, im back. again. with another chapter.

Ultima-owner: Achilles would agree! Also aye, Astolfo's very feminine but that's what makes it fun. Those poor boys...

Valkoor123113: I've been thinking about that too. In the anime, I'm pretty sure the battle I want Astolfo and the others to go all out on has a full or at least crescent moon, but the Manga I don't know. I'm using both, but I'll have to flip through that segment and check again, but if it does I might just toss that detail to the wind because creative liberty. Or I might not. I have multiple ideas for that battle, so he might not even use his spellbook.

Rinto: You're right, there are certain limitations. Take Ivan into account. He's massive and literally made of ice and mammoth. He's unable to move very fast if at all, so he uses lightning to teleport and attack. On the flip side, there are servants like Achillies, who is, I'm pretty sure, canonically the fastest servant barring Dantes. Dantes' phantasm is powered by his... mind. Apparently. He can move as fast as he can think and that's real fast. But on paper, his agility sucks at a D rank. Then there's the third group of servants who are fast in a certain instance or whose stats are unknown. Okita, Astolfo, and Enkidu would fall here. Okita's flash step is as fast if not faster than All Might, but only then. Astolfo could move as fast as All Might but only when mounted on Hippogriff since Astolfo's parameter set as a Rider is hot garbage (he straight-up admits that he's the best at being the worst so take that as you will). Enkidu's stats are all unknown— height, weight, strength, agility, etc. So it's all dependant.

Now, as for Chiron, I'd say yes he can move just as fast as All Might, but he's not going to unless he fights him in close combat. Chiron is more of a 'wait and strike when the opportunity arrives' kind of fighter, as opposed to Endeavor and All Might whose tactics are to go in with guns blazing. Now since Gran Torino is faster than All Might, I'd say that Chiron with all his parameters (full Centaur form) could probably match him, but not outspeed him. Four legs are faster than two.

DL;DR— Certain Servants can match or even move faster than All Might at this point in time. In All Might's prime, I'd say that only Dantes and Achillies could surpass All Might.

That said, I'm not going to go by what the servants' stats are on paper. According to FGO, Yagyu Munenori's agility is the best at A++ on paper. While agility doesn't always equal speed, speed plays a part in agility. I have full faith that Dantes and Achillies could beat Yagyu in agility in a real fight. Also, Li Shuwen's stats are all a literal dumpster fire on paper but he's pretty deadly off paper. So yeah, stats are a bit up in the air.

Frostlash: He's gonna activate Astolfo's Trap Card. I'm not sure what "stu brade astolfos hare" means but I'm gonna assume that you mean Saber Astolfo and don't worry. I have plans.

Suzululu4moe: Oh I see. Yeah basically. The other staff probably won't bother with teasing the poor man though, since he almost died. The Grail's gift was basically my way of saying "hey, Chiron's not a normal servant anymore, the Grail's giving him a bunch of extra stuff even though he can do it on his own". Also, like I said above, I have plans for it. Astolfo's just as cute as some of the other girls, but the focus won't exactly be on Astolfo. Some chapters and sections will be Astolfo Third Person, but a lot will have Chiron or will be mostly one that bounces between the two.

Yaaay exposition. Okay, I'm done here, on to the chapter.

Chiron had explained everything he could to the staff over a secured conference call from Aizawa and Thirteen's shared hospital room.

The space hero, while obscured by a curtain that went around their bed for privacy, had been absolutely delighted to learn that they were co-workers with and going to be teaching two living legends. There were a lot of questions that went around, and Aizawa was aggravated that he didn't connect the dots, but more than grateful that Astolfo had shown up when he did.

Over the call, Chiron had warned the staff about the Nomu, what he had felt and discovered from fighting it. It wasn't a human with multiple quirks, further solidified by Aizawa's input that Shigaraki treated it more like a pet. It could have been human once, but Chiron would have had to have more time with it, the archer had told them. He apologized for killing it without thinking about the police investigation, but Nezu assured him it was fine and the use of his phantasm was omitted from the police report. Obviously, UA would be dragged through the dirt for a bit if word got out, but Chiron told the staff he could have it covered. A hundred years of networking and contact forging paid off and between he and Astolfo had at least four hero embassies and governments behind them, not to mention the Mage's Association— though they were rather reluctant about it.

There was another thing that bothered him, about the warp-gate villain, but he was unsure if it was just because of how close the Nomu was or if it was truly from the villain. Kurogiri didn't feel human either. Not fully, at least, but he wasn't sure. Only Thirteen, Nezu, and Aizawa were told this after the other teachers hung up. Chiron knew he was bound to show his face again and he'd rather confirm his suspicions than go off on a possible theory.

Furthermore, All of the students had been informed via mail that Astolfo had been an early transfer student who had arrived a day before he was supposed to because he recognized that there was trouble. It was brief and more than a bit suspicious, but there was nothing to be done with the sports festival approaching soon. Both he and Nezu hoped that the festival would keep the students' minds from the more than shady way Astolfo appeared.

His mind kept going back to Kurogiri, however. There was no doubt that the blackmist Quirk user was, at one point, a human. There was a vaguely human feeling to him, but it was far too faint. A dead apostle, maybe? He hoped not, because that would mean calling the Church to deal with it and he didn't really feel like doing that. The other option was a more... perfected Nomu. One that was fully coherent and able to think for itself. If that was the case, was the one who created the Nomu further ahead than he had originally assumed? How many others were like the warpgate villain?

All of these thoughts plagued Chiron as he walked down the hall towards Class 1-A. He slid the door open before he frowned, seeing Eraserhead standing at the front of the class. He apparently escaped from the hospital. Despite both he and Recovery Girl's work on healing him over the two days break, the hero shouldn't have been up and moving.

"You should be resting," Chiron sighed as he trotted in, having since discarded his human form now that the students had seen him already.

"Shouldn't your ribs be getting treated?" Aizawa said at the same time, the other man attempting to use the injury that Chiron had sustained to turn the argument onto the archer. Chiron sighed.

"First of all, my ribs weren't broken," he told him, a look reminding the hero of his accelerated healing rate, "Secondly, even if they were, I'd be less of a mummy then you are now."

Aizawa huffed, making a few of his students smile. "The sports festival is coming up," he reasoned, "The students need to know about it and begin preparation."

Chiron sighed. "Aizawa-sensei, you've got two broken arms, your face was smashed in, and you still need to rest. I understand that you have a duty to your students, but do you really have enough energy to deal with all of them and the new transfer student today?" he asked the man, tilting his head towards the door, where two shadows were seen outside it. Aizawa seemed to think about it, stopping his movement before Chiron sighed, giving the man one last push.

"You can sleep while I teach, Aizawa-sensei."

"Alright," he decided almost immediately moving out of the way for the centaur. Chiron smiled, stepping up to the podium.

"So as you all know, we do have a student transferring in early this year," he said. "Some of you might have seen them the other day with me, though their bravery and recklessness comes from their background in the United Kingdom and France."

Some of the students perked up and a majority of them looked over to the door as it opened. Midnight could be seen outside but the real person of interest was Astolfo as he walked in, hands behind his back.

"Hello! I'm Astolfo Charlemagne— oops, Charlemagne, Astolfo! Nice to meet ya!" the boy chirped. Chiron had to admit that the UA girl's uniform did suit the Rider, though then again, he couldn't exactly picture him in anything that seemed to be 'male' oriented. In combination with the uniform, the boy was also wearing black tights under the skirt. Instead of the usual uniform shoes, the Rider had taken a page from the boys' books and chosen to wear the purple converse he owned. Chiron was almost positive the boy had those because of the fact that they remind him of his time with Seig in Trifas, not that he blamed him at all.

The Archer glanced at the students, internally grimacing at the visible flushes on Kaminari and Mineta's faces, along with the pool of drool from the later's mouth on his desk. Yaoyorozu seemed to be staring intently at Astolfo and Chiron wouldn't be surprised if she figured out that something was a bit off about him.

"You can go sit behind Miss Yaoyorozu, Astolfo," he said and the boy nodded, walking over to the empty desk and sitting down. The black-haired girl turned around briefly and nodded to him politely, which was returned with a grin from him.

"Now, onto other things," Chiron said, "I know how big the U.A. sports festival is in Japan, so I do agree that preparation is important. Originally, Aizawa-sensei's lesson was going to be on this."

He gestured to the other man, who grumbled a bit from the yellow sleeping bag he had pulled out from under the podium.

"That being said, the best way to prepare for this festival is to know your Quirk," he continued, which made several students look at each other and Bakugou scoff. He held up a finger.

"'Every Quirk has its limit'," He quoted. "I'm more than certain that you've heard that saying at least once, whether you ignored it or not, this term does stand true. How many times have you considered your own limit?"

That made some students start to pay real attention as he continued. "Some have obvious drawbacks. For example, Midoriya's quirk gives him extreme strength but at the cost of destroying his body. Sato needs sugar to fully power his own up and Uraraka needs to have contact to make someone weightless. The assignment I want you all to do is to find out about the weaknesses and limits of your own quirk and how to best work around them. While brainstorming yourselves, you also need to ask classmates. Just because you think your quirk is limitless doesn't mean someone else hasn't noticed a flaw, and ask me if they can't think of anything. Now, any questions?" he asked and Ashido raised her hand, as did Midoriya (which was expected).

"What's your weakness, Sensei?" Ashido asked after he nodded to her. "I mean, we hardly know anything about your Quirk!"

A few students nodded and he noticed Midoriya pull his notebook out. Chiron sighed but smiled.

"Before I answer that, how many of you looked up the materials I suggested for you to read when you first asked me about my Quirk?" he asked and about half the class raised their hands. "And out of all of you, how many of you made the connection?"

Half of those hands went down and Chiron gazed at the hands that remained raised. He nodded a bit. "I expected more than that, but what's done is done. Tokoyami, would you like to tell the rest of the class of the connection between all of the heroes of each of the stories?"

The boy with the head of a bird blinked before he nodded. "Each of them had a character that was in all of their stories who was also the main Hero's teacher— a centaur by the name of Chiron."

"Good," Chiron said, "So to answer your question, Ashido, and Bakugou's from the beginning of the year, on paper my Quirk is called Sagittarius, but as you can see, it has also given me many qualities of the man in the myth. As you all know, there are three classifications of Quirks— Emitter, Mutant, and Transformation— that are known as general knowledge to the public. There is a fourth category that is so rare it is disregarded and often forgotten. Of those who do pay attention to it, many believe that its origins go back farther than the first quirk appearance. Or perhaps it was born from legends itself. As of now, there are only two people with this classification, known as 'Servant'. This classification was borrowed from an old storybook about mages summoning heroic legends from the past as Servants to fight." He told his students, smiling a bit as he watched even the most bored-looking students in the room perk up a bit.

"The true name of my Quirk is Heroic Legend: Sagittarius in reference to the constellation the hero Chiron became, but it's too long so I always say it's Sagittarius. The Greek Government actually asked for me to change my name to Chiron in order to keep track of me," he told with a slight laugh. "But I'm limited to what I can do. While Chiron is a man of many talents, I'm limited to those. I can improve those skills, but I can't create anything new unless an outside factor is added in. And of course, because of how he died, I'm more wary of poisons and snakes in general."

Most of what he was saying was all lies. Well, to an extent. He was logged into the hero system as such, but he and the rest of the Hero Embassies knew that there was no such thing as a fourth class of Quirks. The common man wouldn't know that though, they didn't have the authority nor the clearance to get that high up in government and medical files.

Midoriya spoke up next after looking up from his note-taking. "You said there were only two people with the Servant Quirk classification? Do you know who the other one is?"

Chiron paused, glancing at Astolfo for a split second. The Rider nodded slightly and he hummed. "Well, I would have assumed it's obvious that I do. And so do rest of you do as well."

Kaminari frowned. "What do you mean, teach?" he asked, leaning back in his seat. "I mean, it's not like any of us in here have—"

He cut himself off as everyone turned to Astolfo, who blinked and then pointed to himself.

"Oh? Is it my turn now?" he asked with a goofy grin.

"So which story is it?" Midoriya asked, leaning towards him and Astolfo put a thumb to his chest.

"Like Ch- er, Sensei, I also was asked to change my name, but by both France and Great Britain," he said, "The one and only son of King Otto and one of King Charlemagne's twelve paladins! The paladin Astolfo! They call it Heroic Legend: Paladin! But I just call it Paladin."

Noises of awe came from a number of the students before Chiron clapped his hands. "As fun as it would be to go farther into the Servant Quirk Classification, we have gotten off-topic."

"Oh! Right! So how do you get around your own limits, sensei?" Sero asked, giving him his usual grin and Chiron smiled.

"As stated, my Quirk allows me to do a number of things, but since I prefer fighting from a distance, I learned hand to hand combat to defend myself should an enemy get too close. My Signature Move would also be considered a weakness. Despite looking powerful, it's only so if hitting in a fatal or vital part of the body or at a weak spot. I can only use it once per day as well," he told the class before indicating to the sleeping Aizawa. "Aizawa-sensei's quirk would be very beneficial to me. I'm more susceptible to poisons because of the way Chiron had died in his legend, Aizawa-sensei can negate Quirks that deal with breathing poison gasses or injecting venom into someone that way, so I wouldn't worry about it. If I get bit by a snake though, there's not much you can do about that aside from hoping for a painless passing."

"That's so grim..." the students said and the Archer just laughed.

Sero nodded, though, as did a few others before Shoji spoke up.

"So that's how you work around your weaknesses and limits, sensei?" he asked through one of the mouthes he created from his limbs. "By learning how to physically deal with it and finding others that have Quirks to balance them out?"

He nodded, "Yes. Every proper hero should. Usually, it is quite uncommon for heroes to work together without a hero-sidekick narrative, but it's possible— some heroes do team up, as you saw with Present Mic and Ectoplasm-sensei's tag team attack at the USJ. Some heroes and sidekicks specifically had support gear that works with the main person they team up with."

"All Might always works alone, though. So does that mean that he doesn't have any weaknesses?" Kirishima asked and Chiron shook his head, sighing a bit.

"It might seem that way, but even he has a weakness. Unfortunately, his quirk restricts the amount of help another hero or sidekick would be able to provide. If someone were to work alongside him, he'd have to pull his punches due to the knockback he creates," he explained, thinking a bit. "If I recall, though, he did have a sidekick for a while. I'm not sure of the details there, but it would be best if he had a support-based sidekick. One who could think ahead for him due to his tendency to rush into battle."

"Endeavor doesn't have a sidekick," Torodoki spoke up, voice even but the Archer could tell there was some bitterness in his tone. Chiron sighed again.

"You're partially correct. Endeavor's agency has over thirty sidekicks, but from what I know of, none of them work alongside of Endeavor on the field. That doesn't mean he's invincible, though. He still has a weakness. I'd say that its the fact that he refuses to admit he has one," he told the white and red-haired boy. "Aside from that, there are times where his fire would be useless in a fight or even make it worse. Though, as far as I know, it hasn't backfired on him in public yet. His hair-trigger temper is also a weakness, and his more hostile nature makes him unlikeable to many— something that heroes do need to think about as well. Charisma and charm are a major aspect of even entering the ranks of the top one hundred heroes."

He pulled some papers from his folder, stepping out from behind the podium and trotting to the front of each row. He handed a stack to each student sitting there before he walked back to the podium.

"Please write any and all brainstorming ideas onto this paper, if you run out of room, feel free to attach more," he told the class and the students started working. Throughout the class, a few asked one or two other questions, though kept mostly to themselves, or were talking with Astolfo. Near the end of class, Chiron started collecting papers.

"I have two things that I'd like to say before you all leave," he said before the class ended and the students turned to look at them. "First of all, I had gone to meet thirteen yesterday and they send their regards. Secondly, I will be giving each of you a written assignment based on the weaknesses that you've provided me, which will be passed out the next time we have class. If you didn't name your weakness, expect a surprise when you get the assignment."

He picked up his folder, smiling again in that pleasant but chilling way.

"Have a pleasant day," he told them before he trotted out of the classroom.

I probably won't be writing a chapter on how Chiron totally destroys the students with their weaknesses. If I do, it won't be for all of them. I actually wrote this chapter before the Endeavor Agency Arc in the manga, so I did have to change a line due to the fact that Moe Kamiji exists! I love her! She's precious and I would die for her, but I probably wouldn't have to because she can take care of herself.

I do have another question for you guys though— should Chiron kill All for One? I'm working on later chapters and curious what you think. Obviously, changes in BNHA canon, but you know. Thoughts?
