Chapter 01: Argonaut

In the early morning of Friday, a car thief raced down the streets in his stolen vehicle, with a police car in hot pursuit.

The thief grinned as he swerved back and forth through obstacles in the road. The 'obstacles' were of course several civilians and fellow cars.

"Hahahaha!" The thief laughed in triumph as he did a particular sharp turn in which he nearly hit a crossing kid. While the thief wouldn't have cared about running the kid over, it would really have fucked up his chances, if he got caught as a murderer than a thief.

Thankfully, before the child could become a splatter of spilt blood and ruptured flesh across the road, a red haired teenager in a school uniform scooped the kid up in his arms while barely dodging away.

"Thanks, kid!" The thief crowed as he sped away. "You're a real hero!"

As he tried to race further, there was a sudden impact to the car side on his right. He then turned to see that he wasn't alone in the car anymore.

It was a white haired youth, relaxing on his chair like he'd been there from the start. He was dressed in an emerald green hoodie longcoat, black goggles, black pants with several minor armor plating on them and steel plated boots. Underneath them all was a tight, black bodysuit.

"Hello!" The youth greeted in a loud, obnoxious tone. "Do you mind stopping the car?"

"Argonaut!" The thief moved to draw a gun but it was quickly grabbed then crushed. While Argonaut tossed the useless lump of metal out the window, the thief tried to reach for a second weapon but then Argonaut's boot slammed into his arm, breaking it. The thief released the steering wheel and clutched his broken arm while screaming in pain.

Luckily, Argonaut quickly took over the wheel, steering the car to a stop. Soon, the car was surrounded by the pursuing police car, along with reinforcements.

"This is the Fuyuki Police Department!" A female officer spoke into her megaphone as various officers took aim. "Open the door and stick your arms out!"

A door opened immediately, causing the officers to gasp in alarm then mutter in confusion as Argonaut stepped out, dragging the groaning thief out with him.

Then in full view of the spectators, he dropped the thief in front of the female officer and greeted.

"Good morning, Officer Yomikawa." Argonaut said over the thief's moaning. "Sorry if this counts as excessive brutality."

"Don't make it sound as if you're one of my officers." Yomikawa nodded her head, sending officers to cuff the thief and haul him into a cruiser. "Now then. I'm obligated to arrest you but..."

"Don't worry about it." Argonaut waved his arm lackadaisically. "I'll make it as glaringly impossible as usual for you to do so."

He clicked his boots together, causing him to rocket upwards as rocket thrusters activated under his boots. Yomikawa sighed as her ponytail blew hair into her mouth, watching as Argonaut quickly became a speck in the sky.

"Someone take that car back." Yomikawa gave out orders. "Also, send a paramedic to the kids that this bastard nearly hit."

Argonaut breathed easily as he flew through the air, invisible thanks to the new adjustments he made on his attire.

"I gotta hurry." His mutter was barely audible over the wind. "Fuji-nee and Issei are gonna gang up on me if I'm late again."

Issei Ryuudou waved an entering student as he waited at the school gates. He impatiently checked his watch, tapping his foot as he waited for someone.

*FFFRRRRRRRRNNNN*

Issei didn't bat an eye as Argonaut touched down a few feet from him, slowing down enough not to damage the road.

"You are almost late!" Issei chastised. "Your actions may be admirable but put too much of your time into it!"

"Sorry." A wave of light washed over Argonaut's clothes, instantly vanishing to reveal the red haired student who saved a child from being run over earlier. "If it's any consolation, I'm here now rather than late."

Issei just sighed and grabbed Shirou Emiya inside. "Let us just get to class."

Shirou packed up as the day ended. Around him were various members of his class, loitering about before leaving. Since Issei had told him that all of the electronics in the school were working fine and nobody was in need of any help, Shirou made his way out of the class to head for his part time job.

"Hmm." Shirou hummed as he walked through the hallway. "I might be pretty late today. I just hope they'll be fine together without me being home on time."

"Thanks for the hard work, Emiyan." Otoko 'Neko' Hotaruzuka, daughter to the owner of the {Copenhagen} and his boss, sent Shirou off.

Shirou quickly hurried home to prepare dinner for four, occasionally parkouring a bit whenever he had the chance.

He had just arrived when he accidentally crashed into a violet haired girl just outside his home. As he got up, he realized that the girl in question was his friend's little sister and a pseudo member of the Emiya Family.

"Oh, good evening, Sakura." Shirou greeted from above her. "Sorry about this."

"Ah, it's fine, Senpai." Sakura Matou replied while blushing and writhing a bit underneath him. "Um, your hand?"

Shirou idly noted that his right hand had somehow been latched unto her large left breast. As he absentmindedly squeezed it, Sakura let out a soft moan which caused Shirou to blush himself and practically launch himself off her, stammering apologies on the way.

"Ah. It's fine, Senpai." Sakura replied. She blushed a bit while looking aside and mumbled. "I really didn't mind it at all."

"Shirou! Sakura!" The two teenagers nearly fell as Taiga Fujimura sped in on her scooter, then launched herself at them. It was only thanks to his training that Shirou was barely shaken while Sakura nearly fell from the impact. "What's for dinner?"

Sakura giggled a bit as Shirou slammed a fist into Taiga's head, rubbing it in and ruffling up her short light brown hair. "We should go inside. We shouldn't let her be alone longer, can we, Senpai? Fujimura-sensei?"

"We're back~" The three said as one as they entered. A girl ran forward from one of the rooms into Shirou's arms. She was an 11 year old girl with black hair with some of it tied in a mid ponytail, and golden-brown eyes like Shirou's.

"Welcome back." Miyu Emiya mumbled into her brother's cloth as they entered. Shirou pulled her off and handed her to Taiga, who instantly buried a protesting Miyu into her large bosom.

"Sakura, help me with dinner, please." Shirou ordered, taking off his school jacket and putting on an apron in one smooth action. "Fuji-nee, don't suffocate my little sister."

"She's so adorable, though." Taiga replied, as she sat down at the table with Miyu next to her. After a small while, the makeshift family enjoyed dinner amongst themselves.

Afterwards, Taiga soon escorted Sakura home while Shirou and Miyu waved them goodbye.

"Onii-chan, one of my classmates was saved by Argonaut this morning." Miyu said as she helped with the laundry, packing away the pegs.

"That was your classmate?" Shirou replied. "I didn't realize. I guess that-"

His sentence was cut off as Shirou suddenly jumped upwards unto their roof. A moment later and Miyu had joined him.

"What is it, Onii-chan?" Miyu asked only for her brother to point out a building in the far distance.

The attention grabbing part? It was on fire.

Miyu sighed a bit. Shirou's attention wouldn't be anywhere else now.

"Just go, Onii-chan." Miyu gently patted Shirou's back. "Just don't come back smelling like smoke."

"No promises."

With that, a flash of light surrounded Shirou again, disappearing to reveal Argonaut once more. He then leapt off the roof with enough force to crack the tiles, flying the rest of the way high up with his thrusters giving him a great lift.

'Alright then, let's go ahead.'

With his longcoat billowing behind him as he flew, Argonaut soon disappeared into the night.
