This is an author's idea about his new fanfiction, you are free to comment about it.
Parody: Record of Ragnarok x Fate grand order
----------------------------------------
(3rd POV)
"Senpai, are you it's a good time to perform another summon? You have just spent a lot of saint quartz on the Christmas event already, even Astolfo saber NP has reached maximum level and all of his skills are maxed out too!" Mash tried to stop Gudako who is walking toward the summoning champer while holding a lot of SQ she got from... nowhere I guess?
"Nothing can stop me Mashu, not even you!" Gudako is full of determination and continues walking toward the room of despair aka the summoning room.
Arriving at the familiar room, Gudako look at the new unknown limited event that just popped out of nowhere yesterday, while there is not even a single description about the banner, no rate up or whatever but there are 13 special servants that are limited to this event only, making it tempting for any gamers.
Even though she already has more than a hundred and fifty servants from the normal pool and limited even pool, it's still isn't enough to satisfy her gacha hunger.
"Dear God please give me a good servant!" Gudako prayed to god... or something that she called gods.
*Insert summoning sound cause idk how to describe it*
Well, as you can imagine, most of the things she summoned is Mapo tofu and black keys, nothing out of order here. While Ritsuka is already on the verge of collapse during the 8th pull, something unexpected happen, the summoning circle suddenly glow brightly, indicating that a high-level servant is appearing.
"Yes! Luck has finally gotten on my side! A servant right in the first pull!" Ritsuka cheered out loud. Her cheerful noise attracted the attention of some servants who just passes by, it's very rare to see Gudako being happy while rolling the gacha and it has been a long time since they have a new companion so they are naturally curious to see the new servant.
The golden light died down and reveal a golden card with a knight holding a sword carved on it. "A saber? Well, I do have a lot of Sabers already but one more won't hurt." Ritsuka said and patiently wait for the card to reveal. As she is looking at the card intensively, some servants have got into the room to see the new servant, there are Tamano, Kojiro Sasaki aka the Regend, Miyamoto Mushashi (Saber), Okita J Soji and finally Nobunaga (archer).
"It's has been quite a long time since we have a new servant to join us isn't it master? Seem like your luck has increased quite a lot." The Regend commented and look at the golden card, even though he isn't a high stars servant but he is proud of himself to claim a unique title among the servants.
However, deep in his spirit origin always desire to become a high stars servant since the stars always have to do something with being stronger and weaker somehow. He has seen those 5 stars and 4 stars servants with their ultimate build shoot out a ridiculous amount of damage he will never be able to reach it with his best build.
"Heh, another golden servant card, I haven't seen any new face for such a long time, what legend will master bring back this time." Oda Nobunaga commented
The card slowly reveals its true form, a tall and muscular old man with silver hair, wrinkled skin, sharp eyebrows and brown coloured eyes. He wears a red and orange haori with numerous flower patterns and a hakama with a darker shade of the same colour tied with a red ribbon. He also wears toe-less leggings that are black. He also has a harbouring long katana as tall as him on his back. On the card showed a fancy 5 stars but it didn't reveal his name.
(Author is too lazy to describe on his own so he copied the wiki)
"You may ask why I'm an old man, as you can see. It's been some 400 years since I ascended and yet I continue to endlessly pursue the way of the blade. Ganryu's evolution is far from over. In other words, this is my golden age!" The old man exclaimed as he step out of the summoning circle and walk in front of Gudako, "I ask you young lady, are you my master?"
"YES!" Gudako shouted excitingly, "Woah Woah have control of yourself young lady, this old man's maybe faint if you shout like that." the old man said jokingly and look around the place, his eyes locked on the group servants or more preciously, looked on the tall young man with an indigo hair.
"Hm, do you mind giving this old man a tour around this place young man?" The new servant moved in front of Sasaki without him realizing it, shocking the group of servants because even Sasaki and Okita has A+ in their Agility parameter couldn't trace the movement of this old servant.
The Regend quickly recover from the shock and agreed to become the tour of the new servant, after all, he is one of the first servants to ever get into Chaldea so he is very familiar with this place. "Goodbye ladies, I will have a look around this place first, see you later."
Then the two men leave the room, leaving the girls in the room confused because of the development, after a few seconds finally remember that she hasn't asked the servant's name yet, his name doesn't even appear on the card.
----------------------------------
{Sometime later}
"And this is the biggest room in the whole facility, the cafeteria, it's also the second most popular room in the Chaldea, second to the training room." Sasaki introduced while the old man smiled brightly. "Oh ho, I haven't eaten for 400 or so years, this smells make my stomach growl pretty bad." The old man laughed and walk into the cafeteria where the red mom, the Artorias and some other servants are busy doing their works.
"Hey young man," He called out for the red Archer, "Hm? Who are you? I haven't seen you anywhere, are you a new servant?" EMIYA asked while doing some cooking for the Artorias.
"I'm indeed a new servant, master has pulled this old man from his grave up and fight for humanity, not the first time I have been in the situation though. Ah, back to the problems, do you mind cooking something for this old man? I haven't eaten anything for 400 or so years." Archer nodded and told him to take a seat, the new servant look around and find a fine spot on the corner, near the bunch of girls who is waiting for food.
Now he has a closer look, the faces of those girls are the same! Are they perhaps related or something? When he was wondering about it, Sasaki decide to sit next to him and bring a jar of water along, "I know what you are thinking about, they are the same person but come from a different universe or timeline if you want to call it." The Regend explained
"Is that so... I wonder if any of my other self can be summoned too, perhaps my younger self when I'm fighting with him." The old man said out loud
*Bam*
The cafeteria door open again and a group of ladies walked in, including Ritsuka, Da Vinci, Okita and Mushashi. They have been trying to find the new servant for some time, Da Vinci is only here because she is interested in the new servant's history while the other servants want to cross their sword with him.
"There you are, you left without my permission, do you know how big Chaldea is?" Gudako scold her servant, he only give her a natural smile in return and tried to calm the monster down. "I will let that problem slide for now but before you can have your food, I wanted to ask you. What is your true name?"
Just before he can answer, a group of child servants run past by while playing hide and seek and accidentally kick the table, making the water jar fall.
"Hm." before anyone could react, the old man used his sword's hilt to catch the falling jar and catch all of the falling water perfectly, he then bring the jar up and drink directly from it.
"Wha- what just happen?!" Gudako asked her servants, most of them is gasping for air while the swordman-woman servants are amazed by how can the old man used his sword with such skills.
"Master, you asked what is this old man's name? I will humbly introduce myself then." He stand up from his seat and said out loud his identity.
"My name is Kojiro Sasaki, the History's Greatest Loser and Humanity's Strongest Swordsman. Also one of the 7 god slayers of humanity."
...
...
...
There was an awkward silence in the entire cafeteria, everyone has stopped doing their work and looked at the old man as his Bio has been opened wide and clear for everyone to see.
