"Looks like someone already came up with the suggestion of Tomoe I was going to do.
In that case, uh...
I guess my request would be Shirou summoning Ushiwakamaru perhaps? She seems like someone he'd hit it off with fairly easily and someone I imagine he'd be a lot more familiar with right off the bat than a lot of other Servants given how popular Ushi's legend apparently is in Japan. I can still see them clashing over how to fight the War of course, but I imagine they'd get along well enough overall that they'd be able to work out their differences somehow." — Quality, answered by Exstarsis
Although Shirou had been once again asked to stay after school to do chores, today he had declined. It bothered him to disappoint people who were depending on him, but he was just too worried about Rider. He'd told her firmly to stay at home while he was in school, but, much like a dog who could smell a cat, he wasn't sure she'd been listening to him. Her gaze had been faraway, raised to the horizon, and she'd bounced on her toes as she nodded absently.
No, he had to get home as soon as possible. He raced through the February afternoon. He'd take her out on a patrol right away and then make some of her favorite foods for her. If he filled her up enough, maybe he'd be able to keep her out of fights another night. Eventually... eventually he knew they'd have to resolve the War. He just wasn't quite ready yet to see that small, feminine figure battered by the weapons of that giant, or blasted by the sword of that foreign queen. If only they had more allies...
As he stepped into the compound, his relief at hearing her cheerful raised voice was almost immediately destroyed by hearing the deep, resonant voice of somebody he despised. He ran to the front door.
Ushiwakamaru threw it open before he could, beaming at him. She'd abandoned the men's shirt he'd loaned her for her usual burlesque take on samurai armor. She looked nothing like the warrior he'd pretended to be as a child, but he was getting used to that. Slowly.
"Master! Praise me!"
"You stayed home, Ushiwaka! Good girl!" He reached to give her the headpats she so craved and then hesitated as she gave him a sidelong look reeking of guilt.
"Oooh, um, nooooo, but praise me anyhow! Come see! Come see!" She grabbed his hand and dragged him as she walked backward down the hall. From the living room came two other voices: the so-hated resonant one and another more sardonic voice.
"I forgot that you said don't go out," said Ushiwakamaru guilelessly. "But I did remember you didn't want me to do anything risky alone!" She pulled him through the open door and waved a hand, displaying her work.
Kotomine Kirei, cocooned in rope, dangled from a ceiling beam over Shirou's dining table, wearing an expression like he'd been eating lemons. His Servant, the blue Lancer, kicked back below him with a can of beer. "So instead I caught the enemy Master and brought him home for you. And I told his Lancer we couldn't fight until you came home and said okay. So? Can we? Can we?"
