After returning to his mansion outside of Fuyuki.
Sakura went to Rider to spend some 'quality time' with her.
Cael went to his office room and called Assassin.
He narrated everything that has happened.
"So, I'm even useless in the battle to you. You can go toe to toe with other servants, you don't need me from the very beginning. Why are you telling me all this?"
Assassin is disheartened by the events. She learned many truths which as bitter to accept.
"The Grail is filled with Archer's soul, he's a demi-god, and his soul is superior to many other servants. The Grail must be filled due to this anomaly, It could grant your wish. If not, I have a way to fill it with"
"What's the use anyway, you said it yourself. The Grail is corrupted, I don't know how it will twist my wish"
"I admit I disappointed you a lot but at the end of the day, I care more about my safety. The Grail certainly won't grant your wish of stopping the destruction of the kingdom but it can reunite you with your love and child. What do you say?"
"Why are you going this far for me? You don't do anything that doesn't benefit you" Assassin asked in a dull tone. She understood Cael in a short time.
"True, I do things that benefit me the most of the time but I want to do things that satisfy me sometimes. You have obeyed me putting your pride aside, that's respect-worthy in my eyes. So, Granting your wish to reunite with your love is the least I can do. "
"Then what about the corruption of Grail?"
"I have a backup plan for that, don't worry, I can make sure it grants your wish, at most, it will consume innocent human lives around"
"Don't you feel remorse for killing innocents?"
"I don't care about the Good or evil ways as long as I get the results. It's not like I actively sought killing others, there's no other choice and it's not like we owe them or anything."
"....Forget it, I don't want others to suffer just because of my wish, it's just history repeating itself. Master, Let's sever the contract, I will go back to the throne of heroes"
"Are you serious? You are giving up your happiness for the sake of some nobodies you never even met? If it's your choice, I respect it but this is a rare chance"
"I'm sure"
"Very well, as a parting gift. I want to tell you this, sometimes humanity diverges from its destined fate, These worlds are called singularities. The 'will of the planet' summons the heroic spirits with the true Holy Grail, it's a divine artifact, a true omnipotent Grail, not a fake like this one to 'save' the world. If one day, you have a chance to get summoned there, use it"
Assassin thanked Cael wholeheartedly "Thank you for the gift"
Cael didn't like her choice personally because he's someone who values personal interests over sacrificing for the greater good/evil.
But he also understands that everyone has their ideals. It's their desires.
And He's not one to interfere with others' ideals even if it destroys them.
Cael gave up his command seals and Assassin returned to the Throne of Heroes.
"I'm finally free, I don't care what happens here anymore. I gained a lot in this war"
He's about to call Sakura and Rider, and when he sensed that they are having sex he stopped.
"Right, I will tell Sakura tomorrow about our departure. I should be turning 27 soon, no wonder my sexual urges have been high recently. I should meet Breanna when I get back"
Cael continued his experiments in his workshop. He tried to find any Japanese clans that have Divine bodies during this wartime but he found nothing. The divine bodies are so heavily guarded that he needed a more active search.
He just gave up since it was not worth the risk. He has another plan that will make him even more powerful and the knowledge of Japanese magecraft will become useless.
The next day, he told Sakura and Rider about the journey to Britain.
"Sakura, you will be coming to Europe with me along with Rider, your apprenticeship will be completed in 2-3 years at most. With your potential, you can figure it yourself I will be just guiding you at the beginning. You can do whatever you like after that. Still, I would recommend not showing off your abilities or skills to the world, staying low key and doing whatever you like "
"Yes, sir"
He reverted to his true appearance which surprised Rider and Sakura.
"Before you ask, yes, this is what I truly look like. Now let's go"
"You look handsome~" Rider complimented.
He already teleported the entire mansion into his reality marble.
He made the squad invisible and they flew directly to Europe with Flight Magecraft.
Flight magecraft became extremely easy after he got the Gravity Jail sacred gear.
After reaching Scotland, he bought a new mansion in a remote city in Scotland for both Rider and Sakura.
Rider began to use mystic code killers she designed herself and wear casual clothes to blend in with modern society.
"I still need to treat you before I began teaching you. I will visit you sometimes and cure you slowly till you are perfectly fine. Then we can start our classes."
He then took out new passports and everything that is required for daily life.
"I also forged these new identities for both of you, use them from now on. Sakura, your information is already in Clock Tower, those crazy bastards will come for you since you don't have a magus family backing you now"
Sakura became thankful for everything Cael has been doing for her and said sincerely "Thank you very much, sir"
"With your level of magecraft, you must be an influential figure in this magus organization right? Why go through all these troubles?" Rider expressed her opinion as she felt Cael is overdoing things.
"No, to the world. I'm just an average magus. I kept all my achievements to myself "
"Oh, make sense knowing your personality. At least, tell us your name now."
"Ah, my apologies. I'm Cael Arsya, even though I don't look like it, I'm Japanese"
After arranging everything for Rider and Sakura. He left to meet with Breanna.
***
---Riverside Mansion----
"Look who's here after a long time, welcome back. You have become so mature"
"Yes, it's been a few years Breanna"
Breanna hugged Cael and she took him inside.
"So, what were you doing all these years?"
Cael observed Breanna, she aged quite a bit. It's been almost 5 years since he last saw her.
He met her ten years back when he was 17 now he's 27 and she's already in her mid 40's then, and now she's in her almost late 50s. She became plump looking old, she has crossed her peak of youth.
"I participated in the holy grail war"
"Oh, that small ritual created by the Einzberns family"
"I call it a waste of time. The ritual is a grand failure. I held on to some hope but it is shattered in the end"
"Don't worry about it. It's just a small ritual" Breanna said, she has some wrinkles showing her aging body.
"Right, why did you want to meet me?" Breanna asked.
"Nothing really, I want to make changes in the contract we had."
Breanna is not surprised at all "I know it is difficult to accept me in my old body. So, what are the changes?"
Cael leaned over Breanna, his face closer to her as he said in a sultry tone "What are you talking about? You are still as beautiful as ever, I just want to eat you up just like before the more you talk to me. Don't talk nonsense like that"
He kissed her deeply and said "Mm~, as I said, you still taste as sweet as honey. Your aging only increased your mature beauty"
Breanna's heart pounded as the scene repeated in her mind again and again. She once again saw Cael, he has grown so much, he's a mature adult now and he has that charm of a mature man, his big figure is unlike the kid she recruited a decade ago.
She blushed as she held Cael's shirt and pulled him closer to her, she held Cael's cheek with her other hand and said
"Don't stop talking, I love it when you say those things to me, please, I need you"
Cael and Breanna spent the next hour enjoying themselves with intense sex.
Cael is genuinely attracted to Brianna, even if he's reborn, he still has the mentality of his 40-year-old self and couldn't see others of his age or someone below 35 as a romantic partner.
Daphne and Touko Aozaki are like kids in his mind.
But Breanna is different.
Cael and Breanna lay on the bed naked Breanna saw Cael's handsome face
"I couldn't believe an old lady like me managed to impress a pretty boy like you"
"In a way, you've been my sugar mama during these years" Cael joked and then said "On a serious note, I genuinely liked you, maybe it's just physical attraction or a side effect of that ritual. Whatever it is, I'm fine with it. And stop calling yourself an old lady, you are just entering your late 50s"
"Thanks Cael but what happened to you, you speak like an old man. I have a question though, do you love me?"
"I don't really call it love, It's just that I don't have anyone I can call friends except for Daphne but she gave up magecraft. Now, you are the only one I'm left with, you can understand me better since we are both in the same profession. Speaking of love, where's your husband now?"
"He's in his bedroom or his workshop"
"Oh, He must have heard us then"
"Aren't you scared?"
"Not really, I don't care"
"It's not like he cares about it anyway, my husband and I have come to an understanding to do our own things"
"I don't get it, Why didn't you divorce him then?"
"We still love each other. It's just that he likes sex with dead bodies after dealing with so much necromancy and I like normal sex. We respect each other's personal boundaries. It's complicated but we are a happy couple"
"A healthy marriage in a magus family is rare"
"Pfft~, stop joking, this is an open relationship. This is not normal"
"By Magus standards, it's healthy"
"So, what are the changes you plan to make about our contract?"
"Nothing much, I don't need the resources anymore. I'm having a good cash flow. Also, I may not ever meet you again"
"That came out of nowhere"
"I heard something interesting is going on in Lost City of Atlantis"
