Shirou learns what's going on

"So..." Shirou says, looking at the 4 girls gathered around the table. "Let's see if I understand what's going on..."

There's this thing called a Holy Grail War, a battle royale between 7 Masters and Servants - who are based on figures from history or myth - in the hopes of getting a wish from said grail. In addition, Saber is my Servant, and the two of you are Masters in this war?"

Rin and the blonde Saber servant nodded, Sakura doing so after. She was just relieved that Shirou only had questions about the HGW instead of him owning things - that would have been complicated, and she might have ended up not be his anymore.

"All right..." Shirou furrowed his brow, taking another deep breath. "This is a lot to take in... perhaps we should have some formal introductions?"

After a brief silence throughout the room, the blonde Saber raised her hand. "I suppose I should start then." She clears her throat, speaking in a very formal tone. "I am the Saber class Servant in this Holy Grail War. My master is Shirou Emiya." She bows to the rest of them around the room. "I would share more, but as there is another servsnt present..." She looks at the violet haired Rider. "I feel safer not revealing my true name in front of a potential future enemy. My apologies." She nods and looks at the other three girls present. Truthfully, the girl in the tight red sweater felt almost like a Servant as well, but it was a bit off to her.

"I would like to go next, Shirou." Sakura raised her hand. In addition to giving some introductions, she could possibly clear the tension in the air. In hindsight, she probably have gone first, but she hadn't expected Shirou's Servant to be so reticent.

"My name is Sakura Matou, formerly Sakura Tohsaka." She started with a hand to her chest, noticing the sudden glances between Rin and Shirou with a bit of satisfaction. "Presently, I am the Master of Rider, a classmate of Shirou's, in addition to his property." The Saber Servant's eyes widened at that. "Personally, I feel that should also make Rider Shirou's Servant as well." She finishes with a glance at Rider.

Medusa sighs, and is about to raise her hand, when Rin shoots her own into the air. "All right. My turn. My name is Rin Tohsaka. I am the heir of the Tohsaka family, sister to Sakura, and the Master of Archer in the Holy Grail War. As for who Archer is..." She blushed and closed her eyes. After a breath, she opened them with a smile replacing her embaressed features and Irises of gold instead of her usual blue.

"And I am her Servant, Ishtar, Babylonian goddess of war and love!" The Servant proudly proclaimed, puffing out Rin's chest. "I am currently inhabiting this body due to unknown reasons, most likely something odd in regards to my summoning."

The eyes flashed back to blue as Rin took over, blushing hard. "I-I did NOT mess up!" She shouted at an empty space, before turning red and blushing even harder, fuming in her embaressment.

"Then I am the last to go." The blindfolded Rider Servant saod with a nod. "I am this Grail War's Rider class Servant, summoned by Sakura Matou." She said, gesturing to her master. "I merely wish to protect her, and find the fact that she is willingly someone else's property slightly concerning..." She paused, glancing beneath her blindfold towards Sakura. "But, in deference to my master's wishes, I shall reveal my true name. Medusa." She finished, getting the expected reactions from those around her.

"As in..." Shirou questioned, recieving a nod from Medusa.

"All right then." The blonde Saber girl noddee, before clearing her throat. "In deference to the two other servants sharing their identity, I feel I should do the same. My name is Artoria Pendragon, King of Knights." She bows forward, stunning everyone again with the revelation that King Arthur was a girl this whole time.

Shirou took a deep breath as he processed all of this. Normally, he would go to bed. But he hadn't made good on using a girl in the house for sexual stress relief yet, and the day would be over in roughly 3 hours... But who to use? King Artoria? Medusa? Rin? Or Sakura?
