A few days later
Training ground 7, Morning
A kid aged around eight or nine with a hair color that could be said weird if he is born in another world and hairstyle which isn't bound by logic with a mask which people found cool before COVID struck and currently experiencing a phase "Being EMO is cool" future closet pervert Hatake Kakashi leaning on a wooden pole.
Next to him a brown-haired girl with purple warpaint markings on her cheek similar age to him resting her head on her hands, scolding a certain airhead and his lousy excuses while stealing some glances at her teammate and looking around so that Kushina doesn't bash her again for not completely losing her fangirl attitude. Credited to the fourth great ninja war in some other world discussions Nohara Rin.
"Hey Kakashi, do you think Obito will at least come on time today ? " asked a hopeful Rin. "A ninja war has better chances of happening than that loser coming on time," said Kakashi with an obvious look. Hearing that Rin went back to her previous antics.
A few minutes later their sensei Yellow Flash fastest in their village Namikaze Minato came into their field of vision followed him is their sensei's girlfriend, their unofficial sensei Uzumaki Kushina. After the couple came close they noticed a small bundle of cloth in Kushina's arms. "Kakashi is it only me or is there a baby in Kushina-nee's hands" enquired Rin for confirmation. "No doubt it's a baby" responded a future cyclops.
"Good morning Sensei, Kushina nee-chan" greeted the not-so-complete genin team.
"Good morning Kakashi, Rin" greeted the couple back.
"Obito is late again huh, looks like the last session is not enough for him. Looks like I need to train Obito's speed again" replied Kushina with a demonic grin and looked towards the baby in a bundle. Listening to this Rin felt sorry for their missing teammate and prayed for him. Kakashi felt almost bad for his idiot teammate, almost. Minato could only sigh as stopping it would also add him to receiving end.
"So who is in the bundle sensei ? " inquired Rin. Kakashi with the same doubt but only with eyes to keeping his tsundere persona intact. "Our nephew, Uzumaki Hiroto " answered a joyful Kushina and also said "Hiroko-san's son" looking at Kakashi. Hearing that Kakashi had a look of sadness and looked at the baby like a big brother. Noticing this look on her teammate's face Rin is shocked as this is the first time, she saw those many emotions on Kakashi's face.
Rin made a mental note to get that answer from Kakashi later. Rin made her way closer to Kushina to take a good look at their younger brother. Kakashi and Minato stood by the side enjoying this moment.
A few moments later everyone heard a loud obnoxious voice
"Sorry, I'm late." said a panting voice of the last member of team 7, the future hidden leader of Akatsuki, the hand behind Hidden mist village's Bloodline clans purge, hailed as the world's greatest lover by some and the world's greatest simp by some others in another world Uchiha Obito.
After listening to that voice everyone turned towards training ground 7's entrance to see a panting boy with black hair, Konoha's headband, and goggles on top of it adorned with an Uchiha crest on his back. "Obito!!! how could you be late again" reprimanded the boy's crush?
After getting his breath back Obito replied with a bashful look "Sorry Rin the future I had to help Konoha's citizens, so helping an old man push his cart I got late". Hearing that Rin grinned with a proud look on her face, Minato and Kushina had a look at each other with small grins and thoughtful looks on their faces.
Before the atmosphere settled in "How many days had you thought of that excuse?" Kakashi took a jab at the goggled kid. "2 days" replied an absentminded Obito. As soon as he realized what he "Wh.. What did you ask ?" stuttered Obito hoping no one caught on.
He saw an angry Rin, sighs from Minato and Kushina, and Kakashi with a proud look.
Kakashi with a smile "Did you lose your hearing from your loud voice, loser ?" took jab.
"Kakashi-teme" shouted Obito with an angry look.
"Did you say something loser?" asked Kakashi with ignorance.
Obito: "Emo"
Kakashi: "Idiot"
They butted their heads and are shouting taking digs at each other.
**BONK**
**BONK**
They clutched their heads at that beating and turned their heads to see an angry red-haired demon. Seeing that look they are afraid and resigned to their fate knowing no there is no one to save them.
At that moment Obito looked at the baby and then at Kushina "Ney Kushina-nee where did you kidnap the baby from ?" asked Obito with a laugh. Next moment he froze at the killing moment directed at him. At that moment he swore he saw a demon from the deepest layers of hell. "You should never poke a mama bear Obito," everyone thought collectively.
For the next half an hour everyone nearby heard pleading and cries. After venting her anger she left a black and blue beaten Obito on the ground. Rin rushed forward and dressed his wounds, explaining what transpired before he made his entry.
Kushina dusted off her hands taking Hiroto from Minato's hands she warned them "Never shout before Hiroto, he might get afraid or else.." finishing off she gave them a look seeing that look the two boys had nightmares for a few days.
To that Kakashi and Obito can only nod their heads in obedience. "It's already a miracle the kid didn't cry seeing that look of yours," thought the boys simultaneously.
"With the introductions done, let's begin your training," said Minato, and Kushina moved to a safer distance and to rest under a tree.
