AN: To answer some questions, I have Tiamat in her first ascension because I like the idea when you Summon the Servant, it's the outfit you first met them in the story. Another is that Sirius and Remus will join the Party, one to make sure Harry is really okay and the other is for Sirius to catch up with the years he's been incarcerated in Azkaban.

Ch 27 A Side Lesson

It's been a few days since the mistrial, and Ritsuka hasn't made any attempts to bring it up. He's been off in the Simulator, often going out in patrols with the Oprichniks and a few Servants.

Mashu spent much time with Sirius and Remus, earning their trust and advocating for their innocence to Kadoc and Goldolf. However, it's difficult considering they still trespassed on Chaldean grounds.

Even with the trespassing charge still placed on them; both Sirius and Remus were willing to cooperate with them. For the chance to meet Harry,

Mashu and Anastasia have devised a plan to help Ritsuka and Sirius repair their relationship, and also give Sirius and Remus to see how Harry is doing. In short, Harry is the plan.

Speaking of Harry, he was enjoying the time he spent in the Russian Outpost. He has gotten to know his Uncle Kadoc a bit with the help of Anastasia, and the rest of the Servants and Staff.

Harry has finished his Studies about Russian History with Professor M. Since he's done, he has some free time to spare, as such he went exploring the Outpost.

Walking through the Halls, Harry was alone exploring the place. Atalante Alter was called out with Tiamat on a Mission in the tundra, something about needing materials.

Harry had Fou on his shoulders while exploring more of the Outpost. He took note of how it's been serious the atmosphere was lately, "Fou, do you have any ideas why everyone's a bit serious recently?" He asked,

"Fou, Fou," The Beast shook his head, unable to answer the young Heir of Chaldea.

"Oh, so you don't know either," Harry said, scratching the little Beast's chin. While he scratches Fou's chin, he doesn't notice that he bumps into someone. "Oof!"

"Hey, watch where you're-oh, young master. I didn't realize you were in the halls." Harry looks up, thinking that he has bumped into his Father due to his voice,

However, he was wrong. Even though they have the same voice, they are completely different. The Man before him wore a dark green suit, cape, and a hat with white unruly hair.

This Man is Edmond Dantes, Ritsuka's guard in the Shadows and Mind. "Young master, is everything all right?" He asked, looking at his master's Son.

"Woah…you look cool!" Harry got up, immediately taking a liking to the Count of Monte Cristo. Mainly the fact his appearance has left an impression on Harry. "Are you a Servant of my Daddy? You have the coolest outfits I've seen!"

The Avenger blinked at what the Child was saying, he smirked and raised his head. "How brazen of you to approach me, Son of Chaldea," Dantes said, complimenting how bold Harry was approaching him.

Harry blinks, looking at the first Avenger that appeared in Chaldea. "Hmm? Why?" He asked,

"Cause I'm an Avenger Class Servant, the personification of Vengeance," Dantes spoke, glaring down at the Boy who wasn't even phased by what he said. "I'm sure you heard about us from your Lessons with the Professor."

Harry shook his head, he knew that many Servants have different Classes based on their Abilities. However, he did not know how many they are in Chaldea. "Just a bit, I only met Casters, Riders, two Assassins, Berserkers, and Rulers. Oh, and Sabers too! Also Archers. There's so many for me to think of."

Dantes nodded, seeing that Harry knew a bit about who they were. "Knowing your Father, you'll be learning about Servant Classes soon enough." He said, about to leave the Heir. "Just wait until that Lesson or ask the Professor about-"

"Can you tell me, Mr. Avenger?" Harry asked the King of the Caverns. "Professor M is busy with Mr. Holmes and Ms. Koyanskaya, and I got nothing to do now…" He said before hearing a low groan.

Dantes sighs, hearing about Harry's growing curiosity. Well, since his master is out on a mission and everyone has their own thing, it's best to give Harry a head start on his Lessons. "Very well, young master." He said, motioning him to follow him.

"I shall tell you what the Servant Classes are," Dantes said before noticing Harry's happy smile. He chuckles, taking that as he's willing to learn.

The two walk down the Halls of the Outpost, "Young master, you're aware we Servants are Historical Figures. Most are Heroes while some are Villains." Dantes stated,

Harry nodded, "Yeah, I met Jeanne D'Arc, Grampa-er Sir Lancelot, Uncle Manny, Da Vinci and so many more." He smiles, answering the Avenger before getting curious about who he is. "Um, Mr. Avenger who are you if you're from History too."

"Kuhahahahaha! In time, young master," Dantes couldn't help but laugh at Harry's bluntness, something he must inherited from his Father. "Now, tell me which Classes you met so far. Take your time." He asked.

Harry thought for a moment before answering. "There's Sabers, Archers, I think Lancers, Berserkers, Riders, and Casters definitely….Rulers…Assassins….um, you Avenger….and…and I think Alter Egos too? I think that's it." He said, feeling like there's more he's forgetting.

Dantes nodded, seeing Harry knew more than he led to. "Excellent, that's impressive that you could remember them, young master." He said.

"First, let me tell you the Seven main Classes." He continued as Harry listened closely.

"First is the Saber Class, Servants who fall into this category are Heroes/Villains who are famous for using the Sword. Such as Arturia Pendragon and her Excalibur."

"Second are Lancers, Heroes who are trained with the Spear. Cu Chulainn who wields Gae Bolg is a fine example."

"Third is the Archer Class, Bowman to make it simpler. The Hero Arash or Atalante are examples of Archers, however, the Class tends to be whoever knows how to use other Weapons as projectiles."

Harry blinks, unsure what Dantes means. "Use other Weapons as projectiles?" He asked,

Dantes chuckles, "There are Archers in Chaldea such as Napoleon who uses a Cannon, or Emiya who tosses his Swords to his targets." The Avenger looks at the young Boy, "Don't think too much about it, young master. Just know that any projectile a Servant uses is most likely an Archer."

Harry nodded, taking a mental note of the Class before Dantes continued with the other Classes. Riders are Heroes with Mounts or Ships, Assassins are People who are in-depth with Presence Concealment or just the name implies, Casters are obviously Magical People, Inventors, or Authors, and Berserkers are Servants who went Mad in their lives.

After Dantes explained what the Seven Main Classes are to Harry, the young Boy proceeded to ask about the Extra Classes. "Mr. Avenger, what about Rulers and Avengers? Can you explain that one, please?" Harry asked,

Seeing they were already far in, Dantes obliges to Harry's request. "Very well, young master. Avengers and Rulers are what we call, Extra Class Servants." Dantes explains to the Boy. "There are many more to the Extra Class,"

"The first Extra Class is the Ruler Class Servants. These Servants are typically Heroes who are impartial to a Holy Grail War. In short, mediators, the laws of Heroic Spirits won't be violated." Dantes explains to the young master. "The Rulers are typically made of Saints, Religious People, or those who have no desire for the Grail."

Harry nodded, seeing that Pope Johanna and Jeanne D'Arc are good examples of Rulers. "But what about Mr. Holmes and Professor M? They told me they're Ruler Servants," He said, seeing no Religious attributes to them.

"Like I said, no desire for the Grail, young master. Sherlock Holmes and James Moriarty are unique cases of Rulers, however, they do not desire to obtain the Holy Grail." The Avenger explains on the two.

"Wait, Sherlock Holmes and James Moriarty?" Harry asked, knowing those names to be famous. "As in…Mr. Holmes and Professor M? They're the Sherlock Holmes and James Moriarty from the books!?" He exclaims, not expecting People from Fiction would be here in Chaldea, let alone real People.

Dantes nodded, confirming what the young master pieced together. "Indeed, Fictional Heroes such as the two Moriartys' and Holmes can manifest as Servants." The Avenger spoke, informing him of what Servants are to the extent. "Servants aren't practically Historical Figures, as long as there are stories about one Person, it can be enough to be a Servant more or less. We call them Phantom Spirits,"

Harry nodded, taking more mental notes about Heroic Spirits and Servants before Dantes continued.

"The next Class is somewhat of an enigma. It was not supposed to exist, yet a famous Mage Family called the Einzberns attempted to Summon a Servant outside the Seven Classes." Dantes explains his Servant Classification to the young Boy. "They are called Avengers, Heroes who are created from resentment that doesn't fade, even after Death."

"So you have some sort of resentment still, Mr. Avenger?" Harry asked, hearing what the Class was.

Dantes smirks, eyeing the black-haired Boy. "Kuhaha! You're very observant, young master." He laughs, hearing about that trait from the rumors. "Indeed, I do hold resentment. I've experienced a betrayal that led me into the Avenger Class."

Harry nodded, "If you don't mind, Mr. Avenger. Can you tell me your name?" He asked innocently, curious who he was.

"Heh, that would be telling, young master." Dantes chuckles, wanting to be a secret for the time being. "I'll give you a hint, search for the King of the Caverns. If you find it, say my name."

Harry wasn't sure what the Count meant, the King of the Caverns. He had never heard that title before, but it left him a bit of a mystery to solve.

"In any case, the Moon Cancer and Foreigner Class is one you're not ready to learn yet," Dantes stated, knowing there are People who are a better fit to teach the Boy. "However, the other four Classes are very dangerous and yet reliable."

Harry listens closely, looking at his new Mentor. "The next Class is known as Alter Ego."

"Oh, I met I think two Alter Egos. One in Britain and the other in France," Harry smiles, remembering them introducing themselves as that Class. "Also, Grandmama, Ms. Koyanskaya, and…Father Kotomine said they're Alter Egos too."

Dantes nodded, "Yes, those are a few Alter Egos you've met here. However, do you know what an Alter Ego is?" Avenger asked the young master.

Harry only has an idea based on the names. "I think, they're Servants who have another identity than the regular one?" He asked, based on the regular meaning he knows.

"Correct, that's what an Alter Ego is, normally they are aspects of Servants who split off from the original Servant," Dantes explains to the young master. "The Hindu Goddess Durga is the perfect example of an Alter Ego. She's another aspect of Parvati and Kali, though she is in the Archer Class currently, her other form Kali is an Alter Ego."

"It's like I said, Alter Ego is another part of a Servant!" Harry smiles, happy that he understood that concept like the others.

"Kuhahahahaha! That's just one example of a proper Alter Ego, young master." Dantes laughs, seeing the Boy has a lot to learn. "In Chaldea's case, Alter Egos that manifest here are known as High Servants; Composite Servants."

Harry paused, confused by the term. "Composite Servants?"

Dantes crosses his arms, looking at the Heir of Chaldea. "High Servants can be tricky, however, they prove to be a powerful ally. They are Heroic Spirits who have other Divine Spirits who make up their Spirit Origins." The Avenger explains to the young master.

"Your Mentor, Professor Moriarty is also considered an Alter Ego with the Divine Spirits of Urd, Verdandi, and Skuld, the Norns. Divine Spirits of the Norse Pantheons who spun the wheels of Fate." The Avenger explains to the young master.

Harry was surprised that there was a different Alter Ego Servants than he thought. "Wow, Alter Egos sounds very powerful." He stated,

"Yes, they are in a way, for the next Class you got Pretenders." Dantes continued with his Lessons.

"Pretenders?" Harry asked, not that surprised that there a more in the Extra Classes. "Are they People who pretend to be someone else?" He asked.

The Avenger was about to answer when someone else spoke for him. "That correct little master, we Pretenders are Servants who became Heroes while feigning another identity." Harry and Dantes look forward, to seeing the same Fairy Man Harry saw back in Britain. "In broader terms, we are actors playing another role."

Harry wasn't expecting this Fairy Man to be here, he smiled greeting him. "You're that Fairy from the British Outpost," He said, pointing at him. "You also showed me where I was staying there."

"That's right, I'm happy you remember me, little master," Oberon said before continuing. "Forgive my lack of introduction, the name's Oberon the Fairy King." The Pretender stated, introducing himself to the Heir.

"Oberon? As in the one from William Shakespeare's Midsummer Night's Dream?" Harry asked, not really expecting that Oberon to be here in Chaldea. Well, if Sherlock Holmes and James Moriarty are here, then he should expect every Fictional Character to be here too.

Oberon smiles, "I see you're well-read in everyone's History. That's something to be proud of." The Pretender commented, impressed that Harry knew that story.

Harry smiles, just when he is about to say something Dantes speaks up. "Oberon, is there a reason why you approach us?" The Count of Monte Cristo asked the Lostbelt Servant.

"Oh, Dantes, I didn't see you there." Oberon lies, obviously noticing the first Avenger in Chaldea. "I was just making my rounds when Lady Mashu requested that I bring the Little master to her. Something about a dinner with Family?" He said to the Avenger.

Edmond frowns, knowing what the Fairy King means. "I see," He said before adding to his words. "Then I shall accompany you two, if master is there then as his shadow I have to be there." He said to him.

Oberon shrugs, not minding the addition. "Oh well, do what you want, Avenger." His eyes shift to Harry, smiling at him. "Now, Little master comes along. Your Family awaits," He suddenly poofs into smoke, revealing a little version of Oberon standing below him.

"Woah! You can shrink, Oberon!?" Harry asked, looking down at the Pretender on the ground. "That's cool!"

"Fou…" Fou mumbles, seeing another competitor for the young master's little companion.

Small Oberon chuckles, looking up at the young Boy. "Of course, I do some recon for your Father and Mother during our time in their missions. But I can travel at a quick pace when I'm this small." He said, leaping onto Harry's free shoulders.

Harry looks at the Fairy King, now sitting on his shoulders. "You really look like those small Fairies in those Storybooks." He commented, comparing Oberon to the Fairies to the ones in the Fairytales.

"Hahaha, please don't compare me to those nice Fairies." Oberon chuckles, seeing the stigma of Fairies that People made was still around. "Little master, Fairies can be dangerous. But that would be for another time, now, onto the dining hall!"

"We'll finish the lesson at another time, your Parents are calling for you," Dantes said, deciding to join Harry on this trip.

Harry nodded, both Oberon and Fou sitting on his shoulders while Dantes followed them closely.

In the dining hall, Ritsuka frowns at the table as his Father is sitting before him.

Sirius felt nervous, both the fact his Adult Son was sitting with him and the fact Harry was here.

However neither said a word to the other, Remus, Mashu, Kadoc, Anastasia, Tiamat, and Kingu were present at the table as well. Mashu did offer Goldolf to attend, but he rather be away from the Family issues if he can help it. All could feel the thick tension around the room between the two, (mainly Ritsuka).

Kadoc leans into Mashu's ears, whispering to her. "(Hey, Mashu, are you sure it's alright for the two to be together?)" He asked the former Demi-Servant. "(I mean, the air is so thick that you can cut it with a knife.)"

Remus overheard the Magus, agreeing with him. "(I concur, Sirius may be willing to help his Son, but the opposite could be said for itself.)" The Werewolf commented, looking at the two.

"(I understand both of you, but Ritsuka can't exactly ban Black-san entirely from his life. He's Harry-kun's Godfather and still has the right to be a part of the Family. He can be stubborn, but sometimes a little intervention is needed.)" Mashu said, explaining her motives.

Remus couldn't help but snicker quietly at the thought of Sirius's Son adopting his Nephew. It may be strange, but it's better than him in the orphanage.

Tiamat cleared her throat, being the one to break the ice. "So, Mr. Black I heard that you were my Grandson's Godfather/Grandfather." The Alter Ego said, "I'm curious, how do you know Harry?"

Sirius turns to the horned Girl, shocked to hear that she's Harry's Grandmother. "Grandson? What do you mean by that?" He asked, getting a bit defensive.

"O-Oh, it's nothing. I also adopted Ritsuka as my own Son along with K-Lancer here." Tiamat quickly explains, sensing some hostilities.

"Oi, you better watch what you say, Wizard," Kingu growls, seeing him being defensive. "Mother is trying to make a conversation with you and you started off by saying something rude."

Tiamat held Kingu's hand, "It's alright, Son. It's understandable-"

"I don't get it, Ritsuka already got a Mother, he doesn't need one more!" Sirius said, feeling like she was insulting Akari by filling the role of Mother to his Son.

Ritsuka glared at his Father, "Be quiet, you don't have the right to call out Mother like that, Otosan. It's common these days to have many Mother figures for a person." He stated, "As for Okasan, she'll always be my Okasan."

"But Ritsuka, I understand that much but-"

"You haven't even tried to understand!" Ritsuka shouted, glaring at the shaggy-haired Wizard.

"Well, I'm trying here!" Sirius exclaims back, "Everything was like a flash to me since I've been in Azkaban, first your Mother has problems with her memory, then I find out you are an Adult, running an Organization that I don't even know, and you and your Wife has adopted your Godbrother!" He shouted back.

"Azkaban? I don't know the slightest what that is!" Ritsuka shouted back, slamming his hand on the table. "You know what's a flash for me? That I just found out that my DAD! Is a freaking Wizard!" He exclaims.

"I only found out when good old Lucius told me about it!" Ritsuka continued, letting his anger out. "The first that I heard of Wizards is when I adopted Harry as my own, then I got more information that you, Sirius Black, a serial killer killed many Mundanes!"

Sirius slams his fist, retaliating against the news about him instead of hearing Lucius's name mentioned. "That was a lie! I didn't kill those Muggles, it was your Uncle Peter no, not Uncle; anyways that daft idiot set off a Blasting Curse!" He stated, explaining what happened. "Fudge was there afterward and assumed it was me who killed Peter and the Muggles! He locked me up because of that assumption!"

"Likely story," Ritsuka rolled his eyes at him,

"It's true! Whatever truth-telling Muggle thing you have, I'll take it to prove my point and-" Just when Sirius continued, the dining room door opened. He and Remus recognized the scent anywhere, their eyes laid on the young Boy standing with a black-cloaked man, and two little Creatures on his shoulders.

"D-Daddy?" Harry asked, getting a bit nervous from hearing the two in a shouting match.

Ritsuka's expression softens upon hearing Harry's voice. "Harry…" He sighs, seeing this was Mashu's plan all along. "Hars, why don't you sit with your Mother? Dinner is about to be served," He said, not wanting Harry to see them fighting or him leaving in frustration.

Harry nodded, quickly walking to where Mashu was. He then noticed three Men looking at him, the two seemed familiar but the other one had dark green hair and violet eyes.

"Harry, this here is your Uncle." Ritsuka motions to Kingu first, sitting next to Tiamat.

Harry looks at Kingu, who obviously didn't want to talk to him. "H-Hello Uncle." He greeted him regardless before shifting his eyes to the two sitting before his Father.

"Well?" Ritsuka looks at Sirius, seeing him staring at him like a Dog waiting for his owner. "Are you going to introduce yourselves?" He asked

Sirius opened his mouth, trying to say something before Remus spoke.

"Hello there, Harry. My name's Remus Lupin, I'm…a friend of your Father," Remus said before looking at Sirius. "That over there is Sirius Black, he's also a Friend of your Father."

Harry smiles, looking at the two Wizards. "Oh, you're Daddy's Friends?" He asked, looking at Ritsuka assuming they were his Friends. "It's nice to meet you-"

Sirius shook his head before explaining, "Um, Pup, we're not referring to Ritsuka, your…Daddy." He said to him, seeing the confused expression. "W-We're talking about your Birth Daddy, James Potter, and your Mother as well, Lily Potter." He said, feeling nervous about this conversation.
