Later that day, after tying up Sakura in a very provocative position and leaving her in her room as payback for her shenanigans that morning, Shirou retreated outside and sat on his doorstep to enjoy the nice weather.
Outside Shirou saw Rider in full combat mode, swinging her daggers through the air like she was practicing.
"What are you doing? It's not like you need to fight anyone anymore." Shirou asked casually as he watched Rider dance around.
"If I don't keep my skills up if I can't protect Sakura." Apparently she hadn't found out that Shirou had bound and gagged her yet. "And it's not like we can rely on Saber, who has gotten lazy. Probably because you pamper her too much." Rider added unnecessarily.
"Well she IS a King." Shirou scratched the back of his head. After a few minutes of watching Rider he got bored and figured he may as well have a little fun.
"You know, your moves are getting pretty stale, Rider." Shirou mentioned casually.
"Stale? Are you saying my skills have dulled?" Rider stopped instantly to listen.
"Well no, I'm just saying that you might want to come up with something new. If someone were to be watching you right now, someone like Caster or Archer could probably learn all your techniques in an instant." Shirou waved his finger around as he explained with a fake seriousness.
"What do you suggest I do then?" Rider stepped forward seriously.
Shirou leaned backwards and stared into the house where Saber was watching something on TV. "I happen to know a secret technique I could teach you." Shirou said with a grin.
"You do?" Rider put her hand on her hip and frowned, unconvinced.
Shirou stood to his feet triumphantly. "Of course I do. It is the Ultimate Technique. Your enemy will be unable to stand before it!"
"Why haven't you ever used it before?" Rider asked with a glare. "If you are lying to me, I am not amused."
Shirou held up his hands. "What would I gain from lying to you? I've never used it before because a good opportunity hasn't arisen."
"Would you teach me this Ultimate Technique of yours?" Rider asked.
Shirou nodded with a wide grin on his face. "Of course! Only on one condition though."
"What would that be?" Rider asked curiously.
"Get on your knees and say "I'm a dirty girl, and I like riding Shirou's sword.""
Shirou immediately had to dodge to the side as one of Rider's daggers flew passed him and stuck itself in the side of the house.
"Right, right. I'm kidding. Don't go all crazy on me."
Rider pulled on the chain and returned the dagger to her hand. "So what must I do?"
"Before that, I have to ask you a very serious question." Shirou's eyes narrowed seriously at Rider.
Rider sighed. "What?" She growled, clearly un-amused.
"Are you a friend of justice?"
"Is this some kind of a test?" Rider tilted her head with a clueless expression.
"RIDAH! ARE YOU A FRIEND OF JUSTICE?" Shirou roared to the heavens.
Rider unenthusiastically scratched the back of her head. "I… I guess so?"
"Then come, there is much I must teach you." Shirou ushered Rider to follow him as they left the grounds of the house and began walking down the street.
Meanwhile, Sakura's senses were tingling as she had super hearing when it came to certain words. "Come" was one of them. Struggling violently she managed to get to her feet, though her hands and legs were still tied and there was a ball-gag in her mouth.
"Mmmph mph mmphai!" Which roughly translates to "I'm coming Senpai!" and she started to hop her way out of the house passed a clueless Saber watching reruns of Iron Chef, staring at the TV with the utmost concentration.
Later…
"Shirou, what are we doing at the pier?" Rider asked as she sat on a bench next to Shirou who seemed to be intently watching the people passing by.
"Patience my young apprentice, we must stalk our prey before we exact justice upon them." Shirou said in the best ancient, stoic way he could think off.
Rider sighed. "If you wanted to go on a date, you could have just asked me." She said as she crossed her arms, tossing her hair to the side.
"You still don't get it do you?"
"What exactly are you talking about?" At this point, Rider was getting frustrated.
"Do you see that man over there?" Shirou pointed towards the pier where a man in a Hawaiian patterned shirt sat smoking as he fished off the pier. Beside him lay beer cans filled with cigarette butts.
Rider squinted her eyes. "You're talking about Lancer, right?"
Shirou nodded. "Yes. You know him as Lancer, but he is an enemy of justice." He said while clenching his fist.
"Why do you say that? He is not hurting anyone." Rider watched Lancer, who just seemed to be absentmindedly fishing the day away without a care in the world.
"Only to the untrained eye. Do you see the destruction that lies around him? He pollutes the world with that crap!" Shirou growled.
"Are you talking about those beer cans? I am not sure I would call that destruction."
Shirou stood up from the bench. "Watch closely, and I will show you all that you need to know."
Rider sighed for probably the tenth time that day. "Fine fine."
Shirou began his trek over towards Lancer, but stopped at the start of the pier. Lancer was maybe ten yards or so away and he hadn't seen Shirou yet. Even whistling a jaunty tune as he stared out at the water.
Without a warning, Shirou began sprinting towards the unsuspecting Servant.
"ENEMY OF JUSTICE, YOUR DAYS OF LITTERING ARE OVER!" Shirou was about halfway there when Lancer started to raise his head to get a look at the idiot who was yelling at him. "RIIIIIDAAAAH-"
Shirou jumped into the air and extended both of his feet until his whole body flew along the pier like some kind of horizontal bullet of justice.
Lancer looked up. "What the fu-"
"KIIIIICK!"
Lancer's face was hit full force with the Ultimate Technique, sending him flying through the air and off of the pier into the water.
"Ooooh!" Rider had watched all this. Now she stood up as well and applauded her teacher, clearly impressed.
"Now Rider! Will you do it? Will you join me and be a friend of justice?" Shirou asked as he returned to her.
Rider nodded enthusiastically a wide grin formed on her face. "I will be a friend of justice and protect Sakura!"
Shirou grinned triumphantly and he and Rider shook hands. Ignoring the voice from somewhere off in the distance screaming "WHYYYY?"
Just then Rider's eyes flashed. "I see it! Another enemy of justice!" Rider pointed towards a restaurant where a tall blonde man was seen leaving it with several women in his arms. His hairstyle was unmistakable as were the large gold earrings he wore as he flaunted what looked like gold coins at the girls.
Shirou put his hand on Rider's shoulders and nodded. "Go and exact justice upon him."
Rider ran off towards the man without a word. Her speed was unmatchable for humans and therefore perfect for using the Ultimate Technique of justice.
Gilgamesh meanwhile was too involved in impressing the girls in his arms that he didn't even hear Rider approach until it was too late.
"RIIIIIIDER-"
"Who dares?" Gilgamesh turned around.
"KIIIIIIIIICK!" The girls screamed and scattered off leaving Gilgamesh reeling as he was hit full force with Rider's kick. He skidded to a halt on the street and was successfully knocked unconscious.
Rider stood up triumphantly and tossed her hair over her shoulder. Shirou gave her a thumbs up in approval. Walking forward and picking up some of the loose gold on the ground Shirou turned back to Rider.
"What do you say we go get dinner somewhere?" Shirou asked with a wide smile.
"Shirou!" He turned upon hearing someone call his name.
"Aw shit. How the hell did YOU get here?" Sakura was running er… hopping towards him. Somewhere along the way she managed to get the gag out of her mouth, hence all the yelling.
"I'm sorry Senpai! Please untie me and I'll make it up to you!" Tears streamed down Sakura's face as she still hopped towards Shirou like some kinda of big breasted kangaroo.
"Emiya Shirou…" Rider's voice was shaking next to Shirou. When Shirou turned to look he saw Rider's body shaking with anger as well.
"Whoa there, calm down. It really isn't what it looks like…" Actually that was a complete lie, but he couldn't afford to have Rider pissed at him right now.
"You… ENEMY OF JUSTICE!" Rider roared.
"God dammit. SAKURA I BLAME YOU!" Shirou turned on the spot and began sprinting down the street as fast as his legs could carry him.
"RIIIIDER-" Behind him he heard Rider's footsteps perusing him, there was no escape.
"Senpai! Wait for me~!" Sakura pleaded as she hopped after the both of them.
"KIIIIIIICK!" Her voice rang out into the afternoon followed by a loud thud.
The people at the pier would long speak of the day that Friends of Justice came to Fuyuki.
