I Am In Naruto

Mizuki "Hahaha, this is a play. It is the same as that time. How funny"

Iruka "Naruto, wake up…. Wake up…"

Mizuki "Now it's time for you to follow him, Iruka. Let me show you my true power"

Mizuki reached the second level of the animal cursed mark. After reaching the second level, Mizuki gained specific characteristics of the animal, along with immense increases in their strength and abilities. Since Mizuki added the extracts of a tiger to the mix, he transformed into a bipedal tiger, with an increase in strength.

Mizuki muscles grew stronger and bigger, and his skin became like an orange tiger. Fangs and claws started to grow.

Iruka: "What"

Mizuki: "I will crush you with full force, Iruka. Well then, come"

Mizuki jumped to the air and punched Iruka, Iruka could dodge it. Mizuki's punch hit the ground, but his punch caused cracks over the ground, causing an explosion. Iruka and Naruto were sent flying.

Iruka: "Damn it. His power is growing again"

Mizuki rushed toward Iruka and kicked him.

Iruka was sent flying, but he stood up again

Iruka "I can't be defeated"

Suddenly, Iruka noticed something. "Hmmm. His power may have doubled, but his body's sharp reflexes seem to be losing their edge. Maybe he diverted his chakra from speed to power. If his speed has dropped, I might find a weak spot"

Iruka stood up, but again Mizuki rushed toward Iruka and gave him a stifle.

"How's this, Iruka? What do you think about this body that I received from Orochimaru-Sama? I will tear you apart"

Mizuki raised his claws and prepared them to stab Iruka, but suddenly, Naruto came and kicked Mizuki. Because Mizuki's speed was decreased, he couldn't dodge Naruto's kick, but he could easily defend it.

Mizuki then threw away Iruka and stared at Naruto "Oh you are still alive, demon fox"

But when Mizuki looked at Naruto, Naruto's eyes changed color to red and his pupils became slit, plus his nails and canine teeth grew longer and sharper. Naruto's hair also grew longer and spikier, and the whisker-like marks on his cheeks widen and thicken, he was surrounded by a layer of red, wispy chakra granting them enhanced strength, speed, and healing.

Mizuki "How did you heal your injuries?

But Naruto didn't say anything, he rushed toward Mizuki. Naruto hit the Mizuki with his punch, his punch created a shockwave, but Mizuki used his hand to punch Naruto. Their punches met each other, created an explosion.

"Boom"

Naruto and Mizuki were sent flying.

Mizuki "Damn it…. is this Demon fox power?"

Iruka "NARUTO, control your power… wake up Naruto"

But then Naruto looked at Iruka, he just smiled at him.

Naruto talked to Kurama in his sea of consciousness

"Kurama, give me more power"

Naruto formed a dense shroud of chakra around his body. The shroud, a translucent red with bubbles of the chakra (reminiscent of boiling liquid) forming all along with it, provided a degree of physical protection.

Then one tail and a pair of fox ears grew from the cloak.

One-tailed Demon fox cloak

Mizuki "Demon… demon…" Mizuki was scared, he tried to run away, but Naruto raised his chakra hand, and the chakra hand grew longer. Naruto caught Mizuki and raised him to the air.

Mizuki "Don't kill me, don't kill me"

Naruto raised one of his hand and started to hit Mizuki faces countless time meanwhile saying "ORA ORA ORA ORA"

After several minutes hitting Mizuki, Mizuki face was distorted. if his mother came and saw his face, she would not know that Mizuki was his child.

After that, Naruto released Mizuki. After receiving the heavy injuries, the chakra beside Mizuki was directed to heal Mizuki, but it's not enough. After that, the animal curse mark power dissipated, he shrivelled up into a malnourished and powerless old man.

Iruka looked at Naruto "Naruto"

Naruto just smiled "the situation is under control, Iruka sensei"

Then the demon fox cloak started to dissipate. He looked at Iruka and smiled. Then Naruto fainted.

Although Demon fox cloak provided a degree of physical protection, but can also harm the user if used to a certain extent.

Iruka "Naruto"

Then Iruka started to check Naruto and found that he just fainted.

Iruka "Thank you, Naruto"
