As the students of Hanzo Academy were heading home for the day, they had no idea that five of their own were staying behind on campus in order to fulfill their secret duties...training to become Shinobi.

Kiraya, secretly a Shinobi Master himself, was sitting by himself playing on a flute, seemingly unaware of the five shadows looming around him, poised to strike.

Suddenly, the five moved to strike but Kiraya's eyes shot open and, with grace, dodged and blocked the incoming attacks. Dodging strikes from blades, fists, a pair of armored greaves, and a closed umbrella, Kiraya soon thrust his hands out, creating a gust of wind that blew his attackers back.

"That was good form, girls. However, there were plenty of flaws in your techniques." He then pointed to each of the girls. "Asuka, you need more aggression, Ikaruga greater speed, Katsuragi height, Yagyuu subtlety, and Hibari precision."

"Yes, Kiraya-Sensei..." The five girls all bowed with a sigh.

Asuka had dark brown hair tied in a ponytail and wearing a red scarf. Ikaruga was a mature girl with long black hair. Katsuragi had long blonde hair with a blue ribbon and had her blouse unbuttoned. Yagyuu had snow-white hair in two twintails with an eyepatch covering one of her red eyes. Finally, Hibari had short pink hair and strange pink clover marks in her pupils.

"You still have plenty of time to improve on your techniques. Do not be discouraged." Kiraya said as he turned to leave before a scroll suddenly manifested in front of him, which he caught.

Opening it up, he read the contents before his eyes furrowed. The message was of utmost importance and needed his immediate attention.

"Girls, keep training together. Something has come up on my end."

With that, Kiraya used a smoke bomb to disappear from view, a common tactic of his to make his presence known as well as make his escape.

"So, have you girls heard about Kiraya's son?" Katsuragi spoke up. "I heard he's super cute."

"He's actually in the same grade as us, Katsuragi." Ikaruga said. "I've spoken with him a few times."

"I've actually met him too! He's really nice!" Hibari smiled.

"He's okay." Yagyuu simply said.

Asuka listened to her friends talking and thought about the one boy she was interested in over others. Despite having hung out with Riyo on the occasion, the two hadn't really gotten particularly close. However, Asuka truly did want to become his friend, he always seemed so lonely.

"I wonder what you're doing right now, Riyo-Kun..."

Kiraya made his way to the headmaster's office, which was run by Asuka's grandfather and the founder of the school, Master Hanzo.

"Hanzo-Sensei, you summoned me, is something wrong?"

The old man chuckled. "Why must something be wrong for me to want to see my old friend?"

"So...nothing's wrong?"

"Well, I didn't say that," Hanzo admitted. "I received important news; a battle between a band of Good and Evil Shinobi happened downtown...they had the Jade Dragon Emperor's Vase."

Kiraya's eyes widened. "The Jade Dragon Emperor's Vase?"

"Indeed...and I sensed that the power held inside has been awakened."

Kiraya felt a bad feeling in his gut. If the power held within the Jade Dragon Emperor's Vase went into the wrong hands, it could spell catastrophe for not just Japan, but the whole world.

"Did you get any information on who opened the vase?"

Hanzo winced nervously at Kiraya's worried glance, knowing he was not going to like what he told him next.

Sure enough...

"WHAT?!"

Riyo slowly opened his eyes to find himself under an unfamiliar ceiling in a barely lit room. He sat up and realized that he was lying on a futon in some kind of cave house.

"Why do I feel like I just got hit by a speeding train?"

"Oh, you're awake~"

Jumping in surprise, Riyo turned to see a girl there. She had honey-blonde hair that was curled at the ends with a large pink bow on top. She was also wearing a yellow sweater, pink skirt, brown leggings, and black boots.

However, what really got Riyo's attention was just how fucking HUGE her tits were. They had to be J-Cup at the least!

"Oh, staring at my chest, are you? You little perv~"

Riyo's common sense caught up with the rest of his brain and his face flushed a crimson red as he scurried away from the futon and ended up bumping against the wall.

"Oh, sorry, was I staring? I don't mean to stare, I just can't help but admire a beautiful girl when I come across...and I'm just digging my grave deeper, aren't I?"

The girl giggled. "How modest of you to say. Normally most boys just can't help but focus on what gets their brains moving the fastest."

"Did you kidnap me? I remember that vase glowing and then the light went inside me and everything went white for a second..."

"Oh yes, we were dealing with some annoying Shinobi that were causing a ruckus in town. Apparently, one side stole a priceless vase and the other side was trying to get it back. When we saw you on the ground unconscious with the vase, we assumed the worst and took them out before bringing you to our hideout."

"Wait...we?"

"Yes, we."

Riyo yelped and nearly jumped out of his skin as he spun around to see another girl behind him. She had short green hair, amber eyes with snake-like slit pupils, and wearing a red sweater and boots.

"Oh my, Hikage. That was a bit unnecessary scaring our guest like that."

"Oh, he's awake?" Another girl's voice chimed in, coming from a cute blonde-haired girl wearing a green tracksuit.

"Phew! For a second there, I thought he was dead for real!" Said a girl with tanned skin and black hair tied in a long ponytail.

"Ugh, did we have to bring him here? Now we've got worthless man-meat stinking up the place!" Barked a tiny girl with long black hair, red eyes, and an eyepatch.

"Worthless man-meat...?" Riyo asked in a slightly hurt tone.

"Come on, Mirai. He's our guest, don't treat him like some kind of intruder." The blonde girl chided.

"But Yomi-Oneesan!"

"Okay, where the hell am I?! Did you guys kidnap me while I was unconscious?!"

"Kidnap is kind of an ugly word." The girl with the pink bow giggled. "We prefer the term 'took you into sanctuary'."

"Well, okay, but I'd like to get home now. Things are way too weird right now and-"

Riyo then paused when he realized something wasn't right. He looked around to find the source but seemed to find nothing so he scratched his head with his tail to figure things out.

Wait a second, tail?

"Oh, yeah, we found you with that on you by the way. Seems pretty stuck on you." The tanned girl said.

After his brain processed the new appendage, Riyo promptly freaked out and began running around in circles, chasing his new tail as the girls watched him in bemusement.

Haruka, the girl with the pink bow, took out a syringe and injected it into his neck, causing him to stop and then slump to his knees before falling on his face, snoring loudly and obnoxiously.

"And he just woke up too..." Hikage said flatly.

"Ugh, why can't we just throw him out?!" Mirai, the smallest of the group, argued.

"Because we don't know what that vase did to him. Do you just want him to wander out alone with no support?" The blonde girl, Yomi pointed out. "Let's cook him something for when he wakes up!"

"Yomi, I swear, if you suggest bean sprouts..." Homura, the tanned girl, groaned.

After waking up again, Riyo took the time to process his newfound tail, which looked like that of a monkey. The girls, who had formally introduced themselves as the Crimson Squad, had cooked up a meal for him with what they had on hand. It wasn't much, but he was grateful for it.

"So you guys are Renegade Shinobi?" Riyo asked.

"For the most part, yeah." Homura shrugged. "We used to be Evil but we disagreed with our old school and went rogue."

"That...is so cool!" Riyo grinned. "I had always wanted to see Shinobi in real life with my own eyes!"

"We're really not all that special," Hikage said. "We're barely scraping a living."

"Most of us have to work part-time jobs just to scrounge up enough cash for food. It's rare for us to be given any missions with a good pay grade." Mirai huffed.

"Thank goodness I have plenty of bean sprouts for everyone to eat!" Yomi said optimistically.

"Just between you and me, Yomi is obsessed with sprouts," Haruka whispered to Riyo, who nodded in understanding.

"We can't just subsist on sprouts forever, Yomi! We gotta have top-quality food, like meat!" Homura argued.

"Ugh, here we go again..." Mirai grumbled before glaring at Riyo. "Don't try anything funny with Haruka-Sama or the other girls. Otherwise, I'll turn you into swiss cheese!"

"Wouldn't dream of it," Riyo said as he patted Mirai on the head. "Aren't you just an adorable little firecracker?"

Mirai's face turned a bright red and she began screaming in angrish as the other girls laughed at her embarrassment while Riyo couldn't help but smile.

"I just hope Dad doesn't freak out when he notices I'm gone..."

"Girls, I have a mission for you." Kiraya said to the Hanzo Main Five.

"Wait is it, Kiraya?" Ikaruga asked, noticing the urgency in her teacher's voice.

"It's my son. He's disappeared without a trace. He was last seen fleeing from a Shinobi fight."

"Has he been kidnapped?" Hibari asked worriedly.

"I don't know. But please, I need you to find him, it's of utmost importance that he's found soon. He found something...serious."

"Serious, huh? Well, it's been pretty boring these past few weeks. Let's go and save us a cute boy!" Katsuragi grinned.

"Katsu-Oneechan! Don't act like a pervert now!" Asuka cried as the rest of the girls followed after the blonde while Kiraya sighed.

"Please be safe, Riyo..."

Riyo has been picked up by the Crimson Squad and for some reason has a monkey tail. But that's just the beginning of the weird stuff that's about to happen to him.
