It was a common fact that there were many rivalries in Chaldea between Ryan's female servants. Scathach and Xuanzang Sangzang fought over who Ryan's true teacher was (even though Chiron was now in a mix with that dispute). Nero and Tamamo fighting over who loved Ryan more. Mashu, BB, and Parvati fought over which of one them was the best kouhai in Chaldea. Heck there was even a rivalry between Alter servants and their original forms.

However, the most intense rivalry in Chaldea was between Saber Artoria Pendragon Alter and Jeanne D'Arc Alter. Ever since both Alter servants were summoned, the two had fought over which one loved Ryan the most as they seemed have the closest relationship with their master. Saber Alter was one of Ryan's first servants and the one who he relied on the most ever since the First Singularity. Meanwhile Avenger, who was originally an enemy who tried to kill multiple times until finally being summoned by the brown haired boy, was his strongest servant in terms of raw strength and the fallen holy maiden believed that Ryan belong to her alone. For the first two years, the two Alters fought until they came to an agreement to share their master since they loved him. Since then, the two girls could be seen together with Ryan occasionally getting into an argument, but still more civilized than they were in the past.

However, it seemed the rivalry had began all over again thanks to his recent summoning of the Alter servants' summer versions. Maid Artoria Alter was determined to keep her master's room nice and clean while training him to be less lazy. Meanwhile, Summer Jalter just wanted to be with him and write manga with her partner which caused his room to be littered with crumbled up unfinished manga pages and trash. So naturally, the two summer girls didn't get along.

So, as Ryan was currently in his room relaxing from all the writing he did at Servant Fest, the boy was just glad to have some peace and quiet after the summer events. Unfortunately, the peace was immediately ruined when Summer Jeanne D'Arc Alter bursted into the room.

"Hey partner!," the Berserker class servant said with a delighted smile on her face. "What are you to?"

"Well...I was just relaxing...," the master said with a sigh.

"Then I'll just join you.," Berserker said as she walked over to her beloved master, sat next up to him on his bed, and snuggled up next to him. "After all, we worked hard during Servant Fest. We deserve a break....maybe we go to the beach and enjoy ourselves for once."

"That sounds like a great idea.," Ryan said causing the manga obsessed girl to smile at him with a slight blush on her.

The two began to lean towards each other, but eight before their lips were going to meet, the door swung open as a certain maid walked into the room.

"Master, you better not be slacking off. A good maid always make sure that her master is always being productive. So, if you want, we can go get some popsicles.," Maid Alter stated before her eyes locked on her rival clinging onto her master. "Excuse me master, but I seem to need to take out some trash....now if you kindly move away, I can—"

"Who are you calling trash, you stupid maid?!," Summer Jalter yelled angrily glaring daggers back at the Rider class servant. "Do you want me to burn you to a crisp?!"

"Bring it on you otaku bitch!," Rider Alter said as the two summer servants began to walk towards each other drawing their weapons. "You're bad influence for my master...it would be bettter if you just disappeared."

"That's it!!! You're so dead!!!," Summer Jeanne D'Arc Alter yelled as the rivals began swing their weapons at each other.

However, before the blades hit, the violence came to a halt when two familiar looking servants walked in the room.

"Hey! What do you two think you're doing?!," Avenger Jeanne D'Arc Alter exclaimed. "Ryan is mine! So stop fighting over him and learn your place!"

Summer Jalter raised an eyebrow at her other self. "But I'm you. So isn't Ryan my boyfriend too?"

"Hmm....good point. I'll have think about this.," Jalter said with a nod. "But I'm definitely not handing over my boyfriend to another version of Artoria!"

"First of all, Master isn't your boyfriend.," Saber Artoria Pendragon Alter stated. "Also didn't you agree to share him with me?"

The dragon witch turned to Ryan's first Saber servant. "Well...yes, but it's bad enough that he has some weird obsession with you. I'm just trying to keep what's mine."

Maid Alter just rolled her eyes as she readied her mop and her gun. "It's seems more trash has appeared that I need to take care of...."

Saber glared at her summer version. "You better not be talking about me."

"Of course not.," Rider said as she pointed to both versions of Jalter. "I'm was talking about these two dragon bitches over here. Once they are out of the way, Master and I can go get ice cream. You can join us if you want."

"Umm....can we all just calm down for a moment? I rather my room not become a battlefield.," Ryan suggested with a hopeful smile.

The four Alter servants just ignored him as they brandished their weapons. Their eyes burned with determination as they were about to go to war. However, once again, the battle was stopped when another pair walked in the room.

"Hi Mister Reindeer!," Lancer Jeanne D'Arc Alter Santa Lily exclaimed with a bright smile before seeing the scene in front of her. "Oh...are the adult version of me causing you trouble again?"

"Why do you always think it's me?!," Jalter and Summer Jalter yelled in unison.

"Because it always is.," Maid Alter stated earning icy glares with from the two fallen holy maidens.

"Well...actually, most of the time it's BB.," Saber Alter admitted.

"Seriously though....You girls need to stop causing Master grief.," Santa Artoria Pendragon Alter stated coldly at the group. "He's been working hard and deserves a break. So, how about we all just calm down and spend some time with Master?"

"Yeah! We can watch a movie together!," Santa Lily suggested with a bright smile that melt the groups' hearts.

"I guess we can do that.," Summer Jalter said. "Besides...I don't want to disappoint my little sister."

"Did you really just say that?," Jalter said looking at her other self. "What happened to you to make you think that way?"

Maid Alter sighed. "I guess I can tolerate being with those two for the child's sake. Just try to not to make a mess...I just cleaned up this room up earlier today." 

"And yet you were willing to destroy it just a few minutes ago.," Ryan pointed out.

"Master...you might want to shut up before the other me kills you.," the corrupted King of Knights suggested.

"Ok.," the brown haired boy said as the group of girls moved close to him as they began to search Netflix for a movie to watch.

It seemed like everything was going to be ok. However, just then the fourth pair walked in the door wearing causal clothing.

"Master...are you ready to go on our date?," Saber Artoria said with a smile on her face. "Oh, is something going on here?"

The other girls immediately turned and glared at their master. That's when he realized he promised to take the original Artoria and Jeanne on date today. He could feel the anger radiating from the Alter servants.

"Hey, my sisters are here!," Ruler Jeanne D'Arc exclaimed. "Can we join you guys?"

"Sure....after we teach lover boy here a lesson.," Avenger said as the Alter girls aside from Santa Lily readied their weapons for the third time today as Ryan immediately tried to run only to be pulled down by the group.

"Poor Mister Reindeer....he never stood a chance.," Santa Lily said as Saber and Ruler tried to keep the other girls killing their master.

Luckily, he managed to calm everyone down by promising to take all the girls on a date.
