Keep your head on

The big sword continued to spin until it was stuck to a tree trunk.

A tall man with black hair and greyish skin appears as he steps onto the sword.

He is a man who is wearing bandages as a mask that covers his mouth. He was shirtless with his chest covered by a belt.

He also wears baggy pants and mimetic wrist warmers extending to his elbows that have the same pattern as his leg warmers.

"This guy is..." Kakashi immediately recognized the identity of the guy that just appeared.

"Well well. If it isn't the hidden mist's missing ninja Momochi Zabuza-kun." Kakashi said.

"Everyone get back. This one is on another level. Tendou, look after everyone until I can finish him off." Kakashi said.

"I will finish this quick," Kakashi said as he revealed the eye that he was hiding with his headband.

"Kakashi of the Sharingan. I was not expecting to see you here. But even then I still have to take care of the old man." Zabuza said.

"But first you have to fight me," Kakashi said as he stared at Zabuza with a red eye that had three tomoe (black swirls that resemble a comma) with a small black circle attached to it which contained a black dot in the middle.

What is that eye? Naruto said as he looked at Kakashi.

"I already got to see the famous Sharingan. I am honoured." Zabuza said.

"Sharingan. What is that?" Naruto asked.

"An eye that can see and counter all types of Taijutsu, Ninjutsu and Genjutsu," Zabuza said.

"Not only that you can also copy your opponent's movement once you see them," Zabuza said.

"I should say I was lucky. After all, when I was in the Hidden Mist Assassin team I read a handbook that includes information about you." Zabuza said.

"But now. Let's stop talking. I have to kill the old man." Zabuza said as he took his sword out of the tree and disappeared.

"But I have to defeat you first." He said as he disappeared.

Not long after that, a large fog screen was created that covered the entire area that Kakashi and the team were in.

"Ninpo hidden mist jutsu."

They could not see anything all they could hear were words that Zabuza said as the fog screen became even thicker.

"The mist is getting thicker," Naruto asked.

"8 choices." Zabuza's voice was heard again.

"Huh," Sakura exclaimed.

"Kidneys, Heart, Liver, Lungs, Spine, Clevical vein, Neck vein, Brain. Which one should I go first." Zabuza said.

He then appeared near the builder.

"Too slow," Tendou said as he punched Zabuza as soon as he appeared penetrating his stomach.

However, his body transformed into water. Tendou thought that he was finally dead so he momentarily let his guard down.

"Be careful. He is using a water clone." Kalashi yelled to warn Tendou.

"Water clone?" Tendou asked.

"Too slow? I should be saying that to you." Zabuza said as he sliced Tendou's head off.

Blood started to gush out of Tendou's decapitated body.

"Kya," Sakura yelled out.

"You bastard." Naruto also cursed at Zabuza.

"Wow. It was really amazing." The decapitated mouth said as it transformed into blue chakra and disappeared into the air.

Only leaving his headband on the ground.

Then out of nowhere, blue chakra started to form a head-like object above Tendou's neck where his head was supposed to be.

Revealing his golden eyes fully. Tendou still looked to be as relaxed as ever like he always was.

Naruto looked somewhat relieved because Tendou seemed to be fine.

But he got pissed off when he saw Tendou's face which became instantly handsome because of his captivating eyes.

Sakura also blushed when she saw Tendou's face.

"Kid! You... You are fine." The builder looked shocked.

Kakashi was speechless.

"Now. Where were we?" Tendou said as he turned back to look at Zabuza who looked shocked.

"Ah, right." He said as he kicked Zabuza in the chin.

"Bang." The kick was so strong that it even made a loud noise.

But Zabuza turned into water as soon as the kick hit him.

Tendou got down on one knee to pick up his headband which he used to cover his eyes again.

"Now. Let's continue our mission. It's already going to be over soon." Tendou said as the mist started to disappear bit by bit.

"What the hell are you?" Kakashi said to himself in a low voice.

Because of the Sharingan, he started to see Tendou's chakra pathways(veins-like organs that transport chakra through the body of a ninja).

But Tendou doesn't seem to have normal chakra pathways. His entire body seems to be made up of chakra without any exceptions.
