Graduation Exam! (4)

Kouga moved his katana, seeing its sharp edge and locked his eyes onto his uncle.

I am fighting for Umbra… and Kouga!

I… will win! No matter how unreasonable, no matter if uncle was a hero, no matter what… I will win!

Lightning Release: Lightning Flow! Arcs of lighting jumped across his body, his nerves further stimulated increasing to give him more speed. His glowing blue iris swirled with light, turning into a sharp gaze.

Naruto let out a small gasp of surprise seeing Kouga's eyes. In the moment their eyes met, Naruto felt time stood still.

That look… that resolve. A flash of images of the past overlapped Kouga's figure. That fighting spirit in his friends fighting together with him back then. Those eyes burning with resolve, like Naruto once was back then… Like Naruto used to be.

A smile subconsciously carved on his lips seeing a true shinobi in front of him, a small fire ignited in his heart almost recalling the feelings he had once. How long has it been since he felt his heart burning like this?

"Come on, Kouga!" He shouted. Kurama's chakra flared even more, the ground trembled and shook.

"Take this!" Arcs of lightning flashed as Kouga rushed like lightning to arrive at Naruto. 

Swish! Kouga swung his katana, a terrifying purple chakra edge cut towards him. Naruto dodged the sharp edge swiftly, a piece of Naruto's hair was cut in the split second. The swing continued to cleave the ground into two destroying their ground!

"You need more experience, brat!" Naruto shouted as he blocked Kouga's hand swinging the blade again, the blade stopped before his face as he launched a kick right to Kouga's stomach.

"Gah!" Kouga felt like he was hit like a truck and was sent flying into the ground, tumbling and spinning, crashing and felling multiple trees.

Moonveil appeared silently, the swing of her spear carried tons of force behind them.

Naruto exchanged ten blows with her, his hands blocking the spear and deflecting her attack. The ground was crumbling, cracking and shattered with each of their blow carrying powerful force.

Moonveil spun her spear, sending her Truth Seeking orbs like a sharp cannon heading straight to him. 

Naruto dodged a few and used his chakra limbs to move out of his way to rush straight at her.

Moonveil rushed with her spear and used her hair as extra limbs, to which Naruto dodged a strike from her hair, but letting her spear pierced through his shoulder as he moved forward with his fist coated with gold chakra. His eyes burning with a regained vigor like the Naruto he once was.

"Mika, you are the same! You need to fight more!" Naruto delivered a fist right onto Moonveil's abdomen, sending her crashing onto the ground leaving a straight gullet.

From behind, blue fire shot towards him as Kouga unleashed a terrifying wave of blue flames. Naruto smirked as he saw the flames rushing to him.

"That won't work-dattebayo!!!" Naruto shouted as he created a Giant Rasengan blocking all the flames at front, sending the rasengan right to Kouga through the sea of flames.

Kouga's gaze turned sharp, his black katana glowed in purple sheen.

I won't lose!

He brought the blade to his waist and slashed out! Iai Slash! A beam of purple light cleaved the ground in half and slashed onto the giant rasengan. The split rasengan flew past him and exploded behind him. Even with his injuries, he rushed forward and once more moved to fight his uncle.

Fist and kicks, Naruto landed hit after hit on Kouga's body. But Kouga wasn't stopping, his hand never stopped moving. As Naruto dodged once more, he landed a counterattack with a fist. Kouga blocked with a raised arm and was launched in the air.

Naruto was about to pursue but just then-

Kouga looked at Naruto sharply, his hands clasped together. 5 Inshin on the ground surrounding Naruto lighted up.

Since when…!

Hidden Technique: True Shadow Binding! The Inshi burst into black tendrils of shadows completely tying Naruto up.

"Moonveil, now!" Kouga gritted his teeth as his palms were pressing tight, as if about to break trying to hold Naruto.

A black pixel cracks in space opened up right in front of Naruto. Moonveil appeared, her Rinnesharingan about to cast the genjutsu.

"I won't lose either! RAH!!!" Boom!

Golden chakra exploded from Naruto's body, turning into a giant golden chakra construct of Kurama. The giant chakra fox formed, Naruto stood inside of it looking at the two with spirit from above. Kouga gasped seeing his uncle's true strength.

"I am going all out, you two!" Kurama's tails launched a frenzied attack towards them.

Kouga and Moonveil dodged left and right. The ground was shaking and trembling as the two kept moving.

Two of Kurama's tails turned into hands, forming two giant Rasenshuriken.

"Take this!" He threw them to Moonveil and Umbra!

A black portal opened in front of Umbra in the next instant, understanding Moonveil's intention he rushed straight through it in the split second it appeared. The Rasenshuriken passed through the portal following Umbra in the next second.

Moonveil was calm, her palms outwards as the two Rasenshurikens arrived at them together.

Preta Path. The Rasenshuriken, unable to hit, shrunk and was absorbed completely.

"Damn it that old grandma…" Naruto complained, but his heart was burning more.

Kouga clasped his hands. "Nue, Reibi!"

A burst of dark and purple chakra exploded from his body, and from it a giant shadow creature with a white mask formed almost as big as Kurama, holding a longsword in its hand.

Moonveil clasped her hands similar to Umbra, the earth beneath trembled the earth and rocks gathered into the Giant Shadow, combining the Golem technique together into a Giant Shadow Golem. 

"Damn you two! You had so many things under your sleeve!" Naruto shouted as his own Kurama's chakra construct rushed towards him. His fists and tails swinging.

"You are so strong, uncle!" Kouga shouted as their Giant Shadow Golem block and counter attacked. His body was destroyed but reassembled endlessly. Each of its swing would crack and destroy the earth similarly to each of Kurama's swing of his tails.

The two giants exchanged multiple blows, creating earthquakes and devastations.

Kouga roared, the Giant Shadow Golem opened its mouth as a Bijuudama formed in its mouth. Kouga raised both his arms, compressing it, controlling it, infusing burning fire chakra into it. The Bijuudama turned into a blue burning star. A Rasengan infused with Fire Release!

Rasenseika! Spiralling Starflame!

"Kouga! You-!" Naruto almost had a smile on his face. To think he knew Rasengan too! It's Tsuyu's son of course he knew. Kurama's giant head opened as Bijuudama created in its mouth, ready to block his attack.

Kouga smiled seeing his uncle being stupid! "Moonveil! Suck it now!"

A portal opened right in front of Kurama's mouth before the Bijuudama could be formed fully, Moonveil rushed forward, her palm touching the Bijuudama and sucking it all up with Preta Path power.

"What!?" Naruto was shocked. And in the next second the chakra was sucked up, Moonveil already disappeared through a portal. Right then,the blue star already blasted towards Naruto.

"Holy Sh-" Naruto cursed-

BANG!

Bright blue light covered the entire west side of the Forest of Death. The explosion destroyed Naruto's chakra construct inch by inch, the flames consuming everything.

As the light dissipated, a kilometer wide radius was covered in flames, with hundred meters from the epicenter scorched black. Any living things turned into charcoal.

A black cocoon opened up slowly, revealing Umbra and Moonveil's figure safe and sound. The shield made of Truth Seeking Orb was strong enough to withstand it.

The two figures looked at the beaten Naruto. His skin burned, and yet it healed visible to the naked eye.

Golden chakra covered Naruto as his skin healed back, a giant fox head covered him in a layer of protection. He smiled even more, ready to engage with them.

"Is that all you two got!?" Naruto roared with spirit.

Kouga roared just the same, his chakra filled the entire Katana, brimming with Purple Lightning that zapped the earth into scorch. Moonveil crossed her arms, sharp bone blades of All Killing Ash Bones protruded out of her palm, ready to cut through even the heaviest defense though never intending to kill him.

Before anyone could make another move, a black portal appeared in between them.

Tsuyu walked out casually, looking at Naruto with a slight smile. It's been so long since she saw Naruto this spirited. She felt a little glad inside, really.

"Now, that's enough." Tsuyu crossed her arms, looking at her brother.

"Eh? Tsu-chan come on, it's not over yet!" Naruto was still filled with fighting spirit. His old bones haven't moved or unleashed his strength to fight for so long and was still aching for it.

"Look… the bell was gone…" Tsuyu glanced at his waist.

"Eh?" Naruto looked down, realising the bell was gone. Not sure where it went. Perhaps it was utterly destroyed at some point without anyone noticing.

Tsuyu chuckled softly. "I believe the two were more than adequate to graduate."

"Haha. Yeah. Alright. They both passed. I couldn't take care of the bell myself so I guess I lost…"

Naruto rubbed the back of his neck. As if remembering it's about the Graduation Exam, he looked around realising how the West side of Forest of Death was razed to the ground at this point. He felt sheepish all of a sudden. 

Did I go overboard?

Tsuyu casually clasped her palms, creating a new forest with Wood Release to cover the losses.

"Suge…" Kouga looked at the forest around them growing, erasing the traces of battle with new life. Impressed once more at how his mother was so casual about everything. Tsuyu turned to face Kouga and Mika, the soft smile never left her lips.

"You two did very well. Though, like Naruto said, you two lack battle experience."

"Kaa-san…" Kouga fidgeted slightly, wondering if he didn't do well enough and she's just saying that.

Tsuyu came closer, ruffled his son's hair a little just to show her appreciation. She knew what her son wanted.

"I am proud of you. You exceeded my expectations. I will give you your graduation gift later." 

Kouga was almost unable to control his smile, his lips curved reaching his ears feeling very jumpy.

"Hehe… I am just doing my best kaa-san!"

"You sure did…" Tsuyu said softly. 

"Mika, you did good as well." Mika nodded hearing the assessment.

She really had only trained for 5 years or so to fight properly and lacked experience as a combatant. Unless she used her Karma that would give access to Tsuyu's own battle experience, Tsuyu expected Mika wouldn't be able to defeat Naruto easily with such a short time training.

Naruto smiled slightly seeing them. 

"Hey… you two. Here's your forehead protector. Congratulations Kouga, Mika. You two are more than worthy."

Naruto shoved his hand into his pocket to get the two their hard-earned forehead protectors.

The ruined, bent, crooked forehead protectors were presented to them. Everyone was silent looking at it.

"Uh, I guess it got damaged while we were fighting-ttebayo! Haha. I will get you two new ones tomorrow." Naruto felt a little more sheepish.

"It's okay uncle…" Kouga looked a bit disappointed. He wanted to wear them right now. 

Tsuyu was silent for a while, before her hand stretched into a crack in space. She snatched two forehead protectors from the storage room in the Academy Building.

"Now, you two are officially Shinobi of Konoha. Remember, don't get complacent. The world isn't kind and dangerous. Even with your strength right now, you could still get killed out there. Remember, always be cautious and plan a few steps ahead."

"Yes, kaa-san!" Kouga stood up straight, receiving the forehead protector like it was his symbol of growth, both as Kouga, and as Umbra. He tied it on his forehead, feeling happy and fulfilled as he ran his finger over the steel plate. 

I am a real Shinobi now… Kouga felt moved and excited.

"What do you two want for dinner? Any place to go?" Tsuyu thought of treating them to anything.

"I want grilled meat! The ones that ate that olive or something!"

"That country you mean. Your dad loved that place too. You should take a bath first. You stink, Kouga."

"Eh?" Kouga sniffed himself, his face scrunched. Yeah he really stinked. The blood and sweat really made him reek. Mika on the other hand seemed spotless.

Naruto chuckled seeing them.

"Hey, Kouga, Mika, that's a good fight we had." Naruto called out before they left.

"Yes uncle! It's a good fight! I would love to fight with you more!"

"Haha! You are welcome to find me anytime-ttebayo!"

"And thanks…" Naruto muttered softly. He forgot how long it has been since he felt like that before. That for a moment, it felt like he returned to his young spirited self. He had to thank Kouga for it. Seeing his eyes and resolve, it brought back his own spirit for a second after feeling empty for so long.

"Hm?" Kouga didn't quite hear what his uncle muttered at the end.

"See you tomorrow, don't be late for the team assignment!"

"Okay uncle!" Kouga waved his hands as he went back home.

Tsuyu nodded at Naruto before going ahead, leaving Naruto behind. She didn't mind if Kouga went to train with Naruto as long as some lines were not crossed. Thinking about it, Naruto really threw Rasenshuriken at her son and used Kurama's chakra and even Sage Mode. Suddenly that time when Naruto was overreacting about her method to train Kouga felt funny. 

At home, Kouga immediately pounced on his dad and pointed at his forehead protector.

"Dad! I graduated!"

"That's my son! Good job kiddo!" Kiba ruffled his hair, feeling happy himself.

"So how was it, did you use dad's super powerful technique on him?"

"Yea! I killed around 5 or 6 with it I think!"

"K-kill? Who?" Kiba felt anxious all of a sudden.

"Just uncle's shadow clones. But the real uncle really is hard to kill. He healed in a matter of seconds like it was nothing!"

"Uh… hey don't casually say that. Don't kill your uncle…"

Kouga suddenly gasped.

"Right… I should have used that earlier!"

"Hm? What idea did you have?" Tsuyu seemed interested.

Kouga's eyes turned serious. "Great Dynamic Marking! I am sure my uncle would have been caught off guard! Damn, why didn't I think of that earlier."

"... Okay." Tsuyu had no comment.

***

Naruto sighed softly. As the fire in his heart left his body, the same coldness returned. He looked at the red barrier disappearing.

It was nice…

He muttered to himself, as if missing his past self that was full of fighting spirit, the will to never give up… Somehow he just felt really tired all over now.

He turned his gaze to the east, he wondered how Boruto was doing with Kakashi handling them. He was sure Boruto would pass, he was strong and a genius after all.

"Hah… I guess I have to write a report for Sasuke now… what a drag-ttebayo…"

Author Note:

Regarding Power Level. As we all know Isshiki trashed Naruto and Sasuke. Like that dude destroyed perfect susanoo with a kick. Kaguya too just destroyed susanoo with a mere palm In anime feat.

Consider 80% otsutsukified Kawaki with scientific ninja tool body and karma activated is GREATER than Isshiki himself.

Kawaki was literally a random civilian and through body modification and otsutsukification/karma he become stronger than adult Naruto and Sasuke at mere age of 15.

The same goes for Boruto that could fight Kawaki at the same age with the same otsutsukification and karma.

And you see, Kaguya herself is slightly inferior to Isshiki. But if she activate her karma, she would stand toe to toe with Isshiki when her skills up to par, and her own hax counter isshiki's dojutsu.

Tsuyu herself? She had more chakra than current kaguya. She had taken Hamura's chakra from the moon back then too, like almost all of it.

As for Kouga, he is 50% Otsutsuki, and he is Tsuyu's own son and not just any Otsutsuki.

80% Otsutsuki like Boruto already surpass his father at 15.

50% Otsutsuki Kouga that received training from Tsuyu herself, had access to ALL jutsu and knowledge there is from Orochimaru and other training he did the past 5 years, perfect Sage Mode to add to it, then Reibi and Nue supplementing a little allowed him to achieve his feats reasonably.

I am writing Kouga's power level by comparing with Boruto/Kawaki with Karma and by setting standard Kaguya = Isshiki
