"I'm sorry!" Nawaki screamed as he ran like his life depended on it.
"You damn brat! Who the hell told you that you can eat my take out from Ichirakus?!" Kushina roared as she grabbed a boulder and threw it at the running boy. Her actions were very reminiscent of Monkey D. Garp when he casually throws heavy and giant cannonballs in One Piece. Instead of cannonballs, Kushina is launching boulders the same size, she used earth release to create at least 30 boulders.
"AHHHHH!" Nawaki hastily dodged the speeding boulder, it's the 6th one he's had to dodge so far.
His only saving grace is he knew Kushina was holding back a lot of strength in her throws. If she wanted to, she could toss these boulders with enough force to easily break the sound barrier. What's scarier is the fact she still wouldn't be using close to her full strength doing so.
The last boulder he just avoided crashed and destroyed several trees in its path.
Sadly, he didn't get any time to rest, another boulder was chucked at him even faster than the last one.
"Oh? You dodged that one too huh? You're pretty good on your feet brat, but that won't save you from my wrath!" Kushina smirked devilishly.
"WHAT THE HELL IS WRONG WITH YOU?! I SAID I WAS SORRY!" Nawaki yelled from behind a tree.
All of this over some ramen? He knew Kushina loved ramen but he didn't think she would nearly kill him over it!
"BWAHAHAHAHAHAHA!" Kushina mimicked Garp's laugh. "Sorry doesn't cut it dumbass, the worst part about it is you didn't even ask if you could eat my food! Be grateful you haven't been hit with my fist of love yet! Bwahahahaha!" She held up her fist to make a point.
Nawaki gulped, he could hear and see her knuckles cracking loudly from just tightening her fist! As crazy as it sounds, he'd much rather deal with bullet-like boulders than suffer a punch from Kushina.
Her so-called 'fist of love' is just as bad if not worse than Tsunade's 'little love taps'.
He can never forget this same little girl can uproot trees with one hand.
"Now quit your cryin! You're a proud Genin of Konoha, take your punishment like a man!" Kushina yelled as she threw another boulder towards Nawaki.
"You damn red-haired demon!" Nawaki cried out while running away again. He had comedic tears running down his face.
Unknown to Nawaki, this wasn't all punishment. Kushina was actually helping him by training his ability to dodge high speed attacks. In her hands, a heavy boulder can travel at faster speeds than a thrown shuriken or kunai.
On the sidelines were Tsunade and Mito, both having different reactions to the sight before them. Tsunade was laughing her butt off at seeing her younger brother's suffering, she told him to not eat Kushina's ramen. But did the little fool listen? Clearly not, so she doesn't feel all that bad for him. Plus she knows Nawaki isn't in any real danger, as absurd as it may sound, Kushina is throwing the boulders at a slow enough speed to allow Nawaki to dodge the incoming attacks.
Mito could only sigh and chuckle, it still amazes her to think Kushina has such immense physical strength naturally. She remembers several days ago where they all saw Kushina effortlessly destroy a mountain with only her fist. No chakra, just her own natural physical strength and the huge mountain crumbles into pieces.
This told her and Tsunade that Kushina can kill a Jonin-level shinobi with a single punch.
The thought made Mito nearly feel pity for Konoha's enemies and eternally grateful that Kushina chose to live in Konoha over any other village.
This also made her realize even if Kushina became the new jinchuuriki of the Nine-Tails, there's no way the village can afford to keep such an asset away from the battlefield.
Eventually Kushina decided Nawaki suffered enough, so she stopped chucking boulders at him. Which made Nawaki sigh in relief, it was finally over.
Unfortunately it wasn't over quite yet.
"Oi." Kushina said.
Nawaki's eyes widened in shock and fear due to Kushina suddenly appearing in front of him. Seeing the look on her face, he knew this wouldn't end well for him.
"Wait! Please don't!" He begged.
"Too late! Now taste my fist of love!" Kushina declared with a wide grin, punching Nawaki on top of his head and sending him face first into the ground. A bit of dust picked up from the impact of the brown-haired Genin hitting the ground.
"Ow! You little red-haired devil! Why did you hit me so hard!" Nawaki groaned in pain, holding this head.
"Shut up! Be grateful I held back 99% of my strength. Next time you'll remember to ask before you eat my precious ramen!" Kushina replied shamelessly.
"Holding back?! It sure as hell doesn't feel that way!" Nawaki retorted.
"Please tell me you don't do that to your classmates?" Tsunade asked. She doubts most of the kids in Kushina's class take the same punch she gave her little brother.
"Of course not." Kushina scoffed, she placed her hand on Nawaki's head then healed him using the Mystical Palm Jutsu. "I'd rather not waste effort having to heal them afterwards."
"…I guess that's a good reason." Tsunade shrugged.
"Please try to keep it that way, you'll end up traumatizing those poor children." Mito said.
"It may be better off if I traumatize them before they are shipped off to the battlefield." Kushina said with a thoughtful expression.
"Kushina!" Mito warned.
"I was only kidding Mito bwahahahaha!" Kushina laughed.
Mito sighed. "Shouldn't you be heading off to the academy? Today is supposed to be the weekly physical tests."
"Yeah I guess I should, looks like it is time to officially assert my dominance amongst the younger generation." Kushina said.
It's been nearly a week since her first day at the academy, as she said before the academy is boring. But she entertains herself by talking to Minato, Choza, Shikaku, Inoichi, Shibi and Tsume and some other kids from non-shinobi clan families. She tried to communicate with Hiashi but the guy has a stick too far up his ass. Until either she or someone pulls it out, Hiashi won't accept her as a friend. Hizashi is different, she got along with him quite well. Jinta Uchiha sees her as a worthless outsider, which is fine since Kushina is targeting Mikoto anyways. So the red-haired girl doesn't need Jinta in order to get close to the Uchiha Clan.
Actually the Uchiha Clan will probably come looking for her once word gets out about her Sharingan.
Currently, she has the best relationship with Minato. Both Tsume and Choza were tied for second.
A couple times after classes she hung out with Minato for a bit. They haven't trained together yet, but they did other things to pass the time. She can tell Minato is nervous about asking her to train with him. This means it'll be up to her to break the ice if Minato keeps hesitating.
Speaking of Minato, Kushina was not surprised to discover that Minato had the largest chakra reserves out of all of the students. Of course not including herself, he'll never be able to come close to her reserves even if he became the Ten-Tails jinchuuriki.
In her estimation, in less than 2 years Minato's chakra reserves will surpass Nikita's sensei's by a good margin. Especially if Kushina trains Minato before they graduate.
"I would hate to be in your graduating class, there's no competing against a monster like you. By the way have you found a boy you like yet?" Nawaki knows it's only been a week but he wanted to get pay back by teasing Kushina.
Kushina rolled her eyes. "No, I'm not into boys. I like women."
"HUUHHH?!" Nawaki exclaimed in shock.
"You didn't know?" Tsunade asked her brother.
"You knew?!" Nawaki retorted.
"We all did, we assumed you did as well considering she told us this information weeks ago." Mito gave her grandson an amused look.
"She did? Oh- no wait you did tell us. I just forgot." Nawaki sheepishly rubbed his head.
"Yeah, just like you forgot to ask if you can eat my take out from Ichirakus'." Kushina grumbled.
"I said I was sorry already, get over it." Nawaki complained.
"Oh? Did I hear you want to taste another one of my fists of love?" Kushina stared at Nawaki.
Nawaki shook his head, cold sweat drenching his forehead.
"Kushina, stop bullying my brother, only I can do that." Tsunade said.
"Some sister you are!" Nawaki glared at Tsunade.
"So do you want me to bully you instead, Tsuna-neesan?" Kushina smirked at the blonde woman.
Tsunade met her gaze fearlessly. "You can try, I won't go down without a fight."
She liked fighting Kushina, it's rare to fight against someone who can tank a full powered blow from her fist and shrug it off.
"Let's go." Kushina was getting excited.
Before this could go any further, Mito spoke up. "Enough! You two can spar later, Kushina-chan please go so you're not late."
"Fine." Kushina sighed before using Yomotsu Hirasaka to leave the Senju residence.
Mito sighed then looked at her oldest grandchild. "Tsunade, stop letting that girl turn you into a battle junkie."
"I'm not a battle junkie! Fighting Kushina is helping me improve my super strength grandmother!" Tsunade denied while crossing her arms.
Mito gave her a look saying 'I don't believe you one bit'.
Nawaki sat down on the ground. "I still can't believe she threw boulders at me over some ramen."
Mito and Tsunade rolled their eyes, not feeling any sympathy for the young Genin.
