Ren went back to his room, trying to sleep but couldn't he was clearly restless. Without anything else better to do, he went to the mountain and started familiarizing himself with his devil fruit.
.
.
.
After familiarizing himself with his new found power, he was satisfied. Summoning the last of his strength, he dragged his sweaty body to cleanse, change to a clean clothes and immediately fell asleep.
He was ready to face his opponent.
…
The next day Ren woke up feeling reinvigorated. Ren went outside and walked towards his training area.
He could hardly suppress his excitement to try his ability again.
His body start glowing, in a flash of light he vanish and appear 5 meters away from where he was standing.
"Sure enough, the ability to teleport is awesome"
He felt the range of his ability to teleport only reached about 5 meters away. Of course, the range would also improve along as he trains.
For now though its enough. His long distance offense is firing laser beam.
An idea dawned upon Ren. he close his eye and open it. The usually brown colored eyes suddenly had a layer of yellow light. As a star-shaped light appear on his eyes, a laser beam shot from it and struck tree from faraway.
As the laser beam reach the tree it explode cloud of smoke surround the tree, after the smoke dispersed, a gaping hole sized of a basketball ball with fire on it burning the tree.
BANG!
The upper part of the tree fell down.
"So cool, I'm like superman and cyclopes now" Ren said as he grinned.
'As i grow stronger in the future, it's penetration and explosive power would be enough to obliberate a mountain' Ren thought as he went to the tree to examine.
He looked at the effect of his ability. Fairly satisfied, he nodded and went in the direction of his apartment .
The reason why Logia is strong fruit is because not only they are immune to physical attack without haki, they can spam their ability with little energy consumption.
He went back to his apartment and ate a meal first before going to the academy
"You arrive…"
When Ren walked into the classroom, Kushina greeted him.
"Good Morning, Kushina-san" Ren said to Kushina as he went to his usual sit in the back.
"did you bring the thing i gave you last night?" Kushina ask
"Hmm, no why?"
"Did you forget? it's graduation test! How are you going to take care of yourself later after you got hurt?" Kushina said whith worry written all over her cute face.
Ren suddenly remember that kushina still didn't know his new found power.
"Don't worry about it, im not going to lose" He smile at her, secretly thanking the god for blessing him with a good friend.
Hearing his confident voice and seeing how relax he was, Kushina was stunned and relax a bit nonetheless she was still worried about him.
After a while, Amarante-sensei came to the class. After encouraging his student he called them to the playground.
He called two names, then they start the test immediately. They could use Kunai and Shuriken but not sword and paper bomb kunai, This is a ninja school after all.
Ren saw familiar face today like Kushina and Minato, Fugaku and Mikoto Uchiha, and Ino-Shika-Cho.
Although Minato is 7 to 8 years old right now, he was already recognize a genius in same age as him, Handsome face with great talent and strength.
Ren's appearance on the other hand looks normal with brown eyes and brown hair.
As Minato already defeated 2 opponents, his fans scream and cheer for him.
Kushina look at Ren worried that he may face Minato, she knew how hard Ren's train. As Amarante-sensei called Ren's opponent her heart almost stop beating.
"Uchiha Fugaku and Kaito Ren, please come forward"
Kushina couldn't understand why her friends first opponent is from a cruel clan and a genius second only to Minato, after thinking about it, it must be a teacher's doing.
"Ren be careful, that guy strong" Kushina said while looking at Ren's with worry.
"Don't worry" Ren assured her as he look at his opponent who's pride is higher than a Mountain. "I will not lose."
For some reason his calm and confident voice calm her as she look at his face seeing his smile.
His teacher, Amarante-sensei, hate all outsider. Amarante-sensei teacher hate him even more when he know he was a talentless outsider, that's why he decided to pair Ren to Fugaku, as he knows how cruel Uchiha treated their opponents, not only he will failed to graduate, his opponent will beat him severely as teacher can't physicaly hurt their student. Ren wishes all teachers to be like Iruka.
"Surrender, as i don't want to be responsible for sending you to hospital" Fugaku said looking down at Ren, in his opinion it's a waste of energy to deal with someone like Ren and people may tease him for bullying a weakling.
He looked at Fugaku with calmness, that its surprise the teacher and other student. "No, you may begin"
"Go Ren you can do it, beat him as hard a you could" Kushina scream while clenching her little fist so hard that its the same color as her hair.
'Him, a trash who can't even use Ninjutsu, beat me? Don't make me laugh' Fugaku harrumph as he look at Ren with contempt.
'I will make sure you regret facing me, Kaito Ren'
"Start" Amarante-sensei said with glee, he couldn't wait to see this trash filled with wounds and blood.
At the mention of that, Uchiha Fugaku took 4 Shuriken in each hand and throw it at Ren.
As the Shuriken clank at each other to change direction, 4 Shuriken go to his weak points while the other sealed his path of escape.
Ren look at the approaching Shuriken calmly as thought he didn't care.
While the crowds think he gives up.
'What the hell is this brat thinking? Shit if he die i'll lose my job, you can die for all i care but don't drag me with your mess' Amarante-sensei thought as he prepared to stop those Shuriken.
"Ren dodge" screamed Kushina as she closed her eyes waiting inevitable, but suddenly heard a surprise sound from the audience.
"How is that possible?" ask Kushina as she look at Ren's direction and see the last Shuriken passing through his body.
Minato who looks bored was amaze with this phenomena.
"What did you do?" a surprise Fugaku ask as he didn't excpect his Shuriken to pass through his opponent body.
Ren did not answer and kept looking at Fugaku.
Fugaku was upset, this guy actually ignore him.
"You think you can defeat me just because of that? Hmph, no one will live ignoring Uchiha" Fugaku said as he dash towards Ren with kunai in hand.
Arriving in beside Ren, Fugaku grin as he slash his kunai towards Ren, when suddenly a glowing fist appeared on his vision, hitting his chest.
POOF!
The Fugaku he punched turn into log that flew like a laser beam as his fist connect to the log.
Body Replacement Technique
"Tch" Fugaku look at log with shock if that him he might suffer an injury.
"You force me" Fugaku said as he finish his handsign and a fire ball spew out of his mouth, heading towards Ren.
"Oh my god' i didn't know he could use that Ninjutsu"
"Im glad not to face that guy"
The crowd look at Fugaku with fear as they did not expect he could use a C-rank Ninjutsu.
Ninjutsu were divided into E, D, C, B, A, S.
E-rank - Learned by Academy students. Are the basic and most fundamental techniques for all ninja.
D-rank - Genin-level techniques. Can be achieved by all genin, though many ninja only learn their "type" of technique.
C-rank - Chūnin-level techniques. Sometimes learned by genin who have trained extensively.
Ren look at the fireball heading towards him without fear.
BANG!
Fugaku pant, Body Replacement Technique and Fireball Jutsu cost him so much chakra. He look at fireball burning Ren's body with a smirk.
"Rennnn..." A worried Kushina couldn't help scream his name.
