Naruto : Saga of Tanya the Kunoichi

Mika opened her eyes, the veins on the sides of her eyes popped out. The Karma in her left hand activated, covering half of her body. Her aura changed instantly, even if her chakra level had no change.

"Come." Tsuyu was calm.

Mika flashed at lightning speed. Godly Vacuum Fist!

Each of her strikes mirrored Tsuyu, the icy ground shattered, chunks of ice and snow blasted each time the two traded blow after blow with the same power. 

Mika used her hair as extra limbs and tools to distract Tsuyu, piercing the ground with each piercing strike.

Kaguya created black rods from her chakra, marked them with Flying Raijin and shot them towards Tsuyu through her palms towards the surrounding area.

Tsuyu smiled slightly.. 

Abyssal Repulsion! All the chakra rods blasted away, not giving Kaguya a chance to utilise Flying Raijin.

Mika pulled Tsuyu with Abyssal Attraction, ready to land her Godly Vacuum Fist.

She pointed her palm towards her, a sharp chakra rod about to shoot, and a portal appeared in front of Tsuyu's palm at that moment. Mika quickly used Abyssal Repulsion!

But in the split second Tsuyu shot the chakra rod into a portal, which connected high above Kaguya not anywhere near her.

Tsuyu was blasted away, but in a second, she appeared from above her in an instant from the chakra rod falling downward toward her earlier!

Kaguya was taken off guard and once more they engaged in close taijutsu. In between Tsuyu's strike she created a chakra rod to shoot and left a Flying Raijin mark behind to shift her positions over and over. Kaguya was still learning, and their fights were confusing to look at with both of them shifting over and over with teleportation.

"Our Rinnesharingan had powerful spatial ability. If you noticed we could see spatial fluctuation based on curvature of chakra before we moved with Flying Raijin. You can predict where I teleport to."

Kaguya nodded, realising the detail. Both of their Rinnesharingan used to the fullest in their fights seeing each other's movements. Using portals to attack and create markers of Flying Raijin at the same time.

Kouga was watching from a kilometer away with his Shiyogan, shivering from the cold slightly while gulping his saliva.

Kaa-san and Mi-chan were too strong! And Mi-chan can use all of her divine fragment to gain Kaa-san's power! When can I use them too!

Kouga felt a little helpless seeing them fight like Gods, their chakra's were like roaring seas as they moved against each other. His heart burned with desire for strength. He tried to tap into the hidden power inside of him, trying to conjure the markings like Mika did and access the same power. 

The seals on his left wrist expanded to cover his entire arm, then his entire self, and he did feel so powerful and glowing in blue colour all over, his blue eyes turned gold too. But compared to Mika and mom, he felt trash even if he looked more awesome. As for the Beast of the Void inside of himself, he was still experimenting. But no matter how he looked at it, compared to Mika right now he couldn't reach her level.

After an hour of spar, Mika deactivated her Karma, feeling exhaustion overcoming her. Both of them received hits from each other, but both of them recovered like it was nothing. In fact their trump card had always been All-Killing Ash Bones. They both could absorb ninjutsu and had a tough body, so their training had always been to utilise reaching the opponent to strike with their killing card.

From testing even a 100% Otsutsuki flesh would corrode. There was no need to worry about power. As long as you can hit, they would be disintegrated at a molecular level.

"You are getting used to the Karma…"

Mika nodded. She never knew you could fight like she did. Tsuyu's experience inside the Karma taught her a lot.

"Kouga! Come here!"

"Yes kaa-san!" Kouga stood up from the snow and ran hurriedly. Tsuyu thought this little guy looked funny somehow. Everyone can teleport, fly or open a portal and this kid just ran. She opened a portal in front of Kouga and just pulled him right to her side seeing he's too slow.

"Eh. Haha thanks kaa-san."

"Are you ready? It's been a month." Tsuyu crossed her arms.

Kouga's expression turned serious. "I am ready."

"Good, Kouga, Mika, let's go." 

The space split into pitch black space connected into an underground chamber. Karin was also there, seemingly waiting.

"Tsuyu, we had them prepared."

Karin was a loyal subordinate of Orochimaru, as no matter what, Orochimaru was the first person to save her. So she decided to continue working with Orochimaru after the 5th Shinobi War along with Kabuto.

Tsuyu nodded.

"Nee-chan, who are you?" Kouga, being curious, asked the pretty sister.

"Ah. I am Uzumaki Karin. You could say I am from the same clan as your mother, a very distant cousin?"

"Oh! More cousins!"

"Kouga, look in front." Tsuyu said coldly.

Kouga felt his heart beating fast seeing the two people chained on the walls. Living people, looking at them with fear.

"Mika. You first… I won't ask you to extract information or anything. I only need you to kill. Both of these were heinous mercenary nin that kill even innocent people."

"What…?" Kouga was shocked that Mika was sent first. He clenched his fists. His eyes downward.

Kaa-san must have thought Mika was stronger and more reliable… while I am weak…

His eyes turned colder, but also filled with determination. His racing heart slowed down as he prepared himself.

He looked as Mika waved her hand, and the person on the chain broke and split apart into multiple pieces with a force from her Byakugan power. Blood splashed all over the surrounding area and the walls.

Kouga gulped, his eyes red from seeing it first hand. Without Tsuyu asking, Kouga already stepped forward. He made a few hand signs, took a breath in and without hesitation blasted a majestic blue fire towards the prisoner. The prisoner was only able to scream in pain for a second before he was burnt into a charred corpse and into ashes in seconds.

His eyes were red, but there were no tears as he looked at what he had done. He killed someone. 

"I did it… kaa-san." Kouga looked at Tsuyu. The child-like expression no more. But it was clear he looked distressed inside.

"Good." Tsuyu nodded with a slight smile, ruffling his hair.

"What do you want for dinner? You did well." 

"I want barbeque." Kouga said in a normal tone. But in his heart, he felt both happy and stressed.

"Sure. Let's go with dad too. He must have felt left out whenever we went to train." Tsuyu chuckled softly, remembering her husband.

A portal opened up right into Kiba's home office. He was handling the Inuzuka clan affairs as usual. Seeing Tsuyu and the kids come, he smiled and quickly went to them.

"Hey I can train with you guys too ya know! How about it, I can teach Kouga and Mika the Inuzuka way!" Kiba grinned. 

"Uh. Dad…- nevermind…" Kouga wanted to say even Mika could trash him at this point but he decided to not say it. And mom seemed far too superior.

"Hm. You are one of the best trackers in Konoha. Kouga could do some training in the area, including anti-tracking methods as well. It would be useful." 

"Yes wife!" Kiba stood up straight, feeling happy Tsuyu actually praised him and let him in to spend time with their children training them.

Tsuyu punched his abs, huffing in light annoyance. He still hasn't dropped his acting.

"Ouchie… You can just say you want to touch em' ya know~" Kiba raised his eyebrows seductively.

"Yeah dad you are really too much…" Kouga scrunched his face seeing how his dad was so affectionate.

"Hehe… I can't help it. I love your mom too much." Kiba raised his eyebrows like a pervert.

"No matter, he won't be able to walk tomorrow morning. He asked for it." She said coldly, but Kiba felt his heart racing instead, anticipating it. He loved that each time… even if he was wrecked. Tsuyu was definitely already casual with him after years. Just a normal thing between wife and husband, or so she convinced herself.

Mika blushed slightly, while Kouga opened his mouth wide hearing her remarks. Not mom too!

***

The family of 4 ate dinner. Kouga seemed a little quieter than usual. He had blood in his hands after all. But, he thought to himself he had a responsibility to uphold and firmed his heart. Mika as usual stayed silent, but her eyes told everyone she had always been listening.

Kiba noticed the smell of blood really. His nose was already sensitive. But, he understood Tsuyu's education and accepted her decisions. Besides, their children were very smart and mature in their own ways. Tsuyu may be a little strict, but he understood it was all for their children. And he decided to be their children's doting father to add warmth for them.

"So how was training with mom today?"

Kouga huffed. "I am too weak… even though I carried mother's Divine blood… I felt mortal… Mi-chan did so much better."

"Ahaha… is that so. No matter, you have time to become stronger! Ya know, back when your mom was your age…"

"Um… nevermind." Kiba rubbed the back of his neck. He wanted to say Tsuyu too wasn't as strong as she was now. But even then she was the brightest among them.

"Huh. So how was mom back then!" Kouga looked at Kiba, waiting for an answer.

"Hehe… You know, the first time I saw your mom, I thought she was so cute, pretty, polite, humble, really nice to talk to…"

Tsuyu rolled her eyes. Kiba began to tell his story, how Tsuyu turned out to be this strict girl and beat him up. At the academy Tsuyu was always bright, admired by all, no.1 genius of her generation.

Kouga had his eyes shining hearing Kiba's tale and his mom.

"Wow…" 

"Heh. You haven't heard her story during the 4th Shinobi War. Hero of Konoha. But for the enemy, she's called…"

"Demon of Konoha."

"Gasp." Kouga felt his heart accelerating fast, his awe for his mom shot up to 500%. The moniker was so damn cool!

Kiba chuckled. "Yeah she was really awesome back then. Konoha was all on her shoulder. If not for her, we wouldn't be here ya know."

"Oh there was a hidden story. You know, your mom defeated the 4th Raikage and the 3rd Tsuchikage on her own!"

"Hehe. Your mom is so awesome right?"

"Yeah! Kaa-san is so awesome!"

Tsuyu huffed, hiding her embarrassment.

"I just did what I could, that's all. I only wanted peace. And now we have it. Don't waste what we had fought hard for. That was why I really disliked the idea that you wanted to become a shinobi in the first place. It wasn't easy. It was bloody. A hundred thousand lives were in my hands, Kouga. No one mentioned it anywhere, did they?"

"Hundred…thousand?"

Kouga didn't say a word, processing such an unreasonable number. Kiba gave a signal to Tsuyu to not mention it anymore. But Tsuyu ignored it. She wanted her own son to understand the price of peace today.

"I destroyed all of Kumogakure. As a threat. That, achieved peace." Tsuyu wanted Kouga to understand the cost of peace.

"... All of them…"

"Like Konoha you have now. The people you see around you. Your cousins and friends. They were the same. I turned them to dust."

"... Wow…" Kouga felt stunned. It sounded a little unreal.

"You don't think I did too much?" Tsuyu turned to look at Kouga, wondering what he was thinking.

"No… I just thought…you are so strong… You did what you should, kaa-san."

Tsuyu's eyes softened. 

"You are different from your uncle. He was crying for their lives, calling them innocents."

"I mean, those people are strangers so I don't really care much…?" Kouga honestly scratched his cheek. As if those stories were just a tale or a number to be told.

"Good mindset to keep." Tsuyu nodded. Kiba didn't comment, and instead changed the topic to keep eating the barbeque.
