Knock! Knock!
"Come in"
Ren enters the Hokage's office then does a quick look around and notices two teenagers standing in front of Sarutobi.
"Ren, these two here are a substitute Anbu like you." Sarutobi stopped for a moment to smoke his pipe while also looking at the two teenagers nodding at Ren who nod back.
"You three will head off the village to deliver a supply of food and medical stuff at Sakumo camp at the same time help them if they needed." Sarutobi handed five scrolls to Ren.
"Ren, as you are the strongest amongst the three of you, you will be the leader of this mission."
"Yes, Hokage-sama"
'Is the Second Shinobi World War already started?' Ren thought while walking out of Hokage office.
•••
"Good job, you three. Did you see any suspicious person while traveling here?" Sakumo said while taking the scrolls out of Ren's hand.
"No sir" Bunji replied while saluting at Sakumo. While traveling, Ren got to know the two teenagers names.
"Good, rest well tomorrow you three will help us around here."
"Sir yes sir!"

Before Ren noticed, a month had passed.
During this month, Ren Bunji and Aina got busy helping around, retrieving Konoha's Ninja corpse, being support etc. etc.
Although the three of them did not join at the frontline as Sakumo didn't trust them to follow his order.
Currently, the three of them are heading back to the camp as their scroll is already full of corpses.
"The co -corpse this time is even more than last week..." Aina said with a weak voice.
"Yeah..." Bunji also said with a weak voice, they witness the cruelty of war for a whole month but still not used to it.
"Captain, I can't believe you stay cool this whole month even after seeing so many corpses." Aina said as she looked at her silent Captain.
Silence.
Ren didn't answer as he himself didn't know why, shouldn't he freak out as he is from a peaceful era back on earth?. Ren is more confused than the two of them.
Aina and Bunji look at each other before following their captain.
Ren continued hopping from tree to tree, however, this time the tree he stepped on glow before exploding.
BOOOM!!
The explosion engulfed Ren shocking both Aina and Bunji.
"CAPTAIN!" Aina and Bunji scream while their back is touching preparing for battle.
"I'm fine, we're ambush" Ren appears beside the two who look at Ren like they are seeing a ghost.
Whoosh! Whoosh!
As Ren reminds his team, many Shinobi appeared and surrounded them, all of them have Iwa [Earth] headbands.
"All of them look strong..." Bunji sweat dropped at so many enemies in front of them.
"... They should be all Chuunin or even more than that" Aina said fearfully all the while thinking on how to escape.
"Doton: Doryuudan no Jutsu [Earth Release: Earth Dragon Blast]" one of the Ninjas in front of them suddenly cast Ninjutsu, followed by the back, left and right side enemy.
A large mudstone structure appears from the ground in the shape of a dragon's face. The dragon then opens its mouth to shoot many earthmud "cannon balls" which head towards Ren and his team from all directions with great speed.
Bunji looked at the incoming cannon balls fired at them from all sides by their enemy dreadfully, closed his eyes and bit his lip to the point blood came out of it, then opened his eyes with determination.
"Doton: Iwa no Doomu! [Earth Release: Earth dome!]" Bunji slams both his palms at the ground.
"Captain and Aina-chan, this dome requires a great deal of chare but because i have a small chakra reserve, i can hold it for a few minutes before it exhaust my chakra, so please be prepared." Bunji quickly informed the two.
"And please tell my parents that i love them." Bunji said with tears planning to sacrifice himself, as the dome needs him to remain in contact.
"Bunjiiiiiii..." Aina screams his name as the dome is about to close, but before the dome gets closed a light of flash and Ren is gone beside Aina.
Ren appeared at the top of the dome with two basketball size Light Blast, Ren then aimed one of the Light Blast behind Bunji while the other at the front of the dome.
BOOOM! BOOOM!
The two Light Blast move at the speed of light at the front and back earth dragon, destroying it and killing the caster, while those who are close at the earth dragon caster were blown away by the explosion.
Ren created two more Light Blast and sent to his left and right side earth dragon.
BOOOM! BOOOM!
Meanwhile, two buff Iwa Ninja jump at Ren with their cocked armed covered rock and punch Ren at the same time.
Clattering!
Instead of hitting Ren, their fist covered rock passthrough Ren's body and hit each other fist.
"What?!"
Surprised and confused, the two jump back to their original position, while another two Ninja pick up a large border found in the vicinity and send it flying towards Ren.
Ren push both his hands and barrage the boulder with Light Blast.
Crack!
Ren manage to destroy the boulder but before he can fight back, a barrage of kunai attach with paper bomb head towards him.
"Captain..." Bunji said with fear while looking at the paperbomb kunai flying in their direction.
'Shit, i almost forgot this guy...' Ren click his tongue, he then teleports beside Bunji and princess carry him.
He got slow down by Bunji's weight but still fast enough to dodge those damn paperbomb kunai.
KABOOOM!
A huge explosion created by many paperbomb kunai.
"AINA-CHAN!!" Bunji kneel down crying beside Ren, while Ren widen his eyes at the fact that he didn't save Aina.
Ren didn't wait for the dust and smoke to clear and directly teleport at dome's location, only to find a crumble dome.
The dust and smoke created by explosion become his smokescreen while searching for Aina.
He finally find her under the rock unconscious, he push the rock crushing her stomach out and pick her up without checking her condition as his smokescreen is about to disappeare and teleport beside at Bunji location.
"Captain??" Bunji look at his Captain silently putting Aina down beside him.
"Look after her while i deal with enemy"
"What? Are you cra-" without waiting for Bunji to finish his words, Ren teleport to where the dome is located and face the enemy.
Then Bunji watch unbelievably his captain with wide eyes and pale face.
"He is so fast we can't even land a hit..."
"Dammit, who tf is this guy? I didn't know Konoha has such a Ninja..."
"Monster..."
Massacre...
Bunji is shaking with fear as his Captain appear and disappear and everytime he appears an enemy died.
'I didn't know Captain is this insanely strong...'

"Let's go!" Ren suddenly teleport back and pick Aina up.
Bunji didn't respond as his attention is still on the battlefield filled with Iwa Ninja corpes while their blood dyed the land.
"Dead?... All of them are dead...?" Bunji mutter but Ren heard it.
Ren sigh and walk at the daze Bunji and tap his shoulder to get his attention.
"Can you walk?" Ren asked when he got Bunji's attention.
"Y, yes" Bunji tense reply and took Ren offer hand to stand up.
"Then lets go!" With that, the two hop on tree while Ren carefully carrying Aina.

At Village Hidden in the Grass.
Sakumo's camp is located near the border between their allied country, Grass country and their enemy, Iwagakura.
Currently, Sakumo standing and giving order at Yamanaka sitting on the ground beside him eyes closed, whose acting like their telephone using their mind arts.
A Ninja suddenly rushed inside the camp.
"Sakumo-san, Ren and his team came back and said they were ambushed by Iwa Ninja."
The Ninja immediately report.
"How the hell those bastard manage to sneak with our scout Ninja??" Sakumo ask the kneeling Ninja, dissatisfied at the scout group.
"I don't... know sir"
"Hmph, quickly bring Ren here and his team."
"Right away sir"
Ren came inside and immediately report to Sakumo.
Sakumo stayed silent during Ren reports and whe Ren finish reporting he was shock, although he know Ren is strong, but the fact that he kill so many Ninja shock him.
"Leader?"
"What is it?" Sakumo look at Ren.
"Can i sent Aina back to let Senju-sama heal her?"
"Hmmm, understood and tell Tsunade to heal her in my name as that girl price for healing is expensive. Also do it tomorrow for now you rest."
"Yes sir"
•••
Ren walk to their tent and look at the still unconscious and covered with injuries, Aina.
'I am careless, this must not happend again.'
