The Eight-Year-Old Me Became Hokage

When Tobirama saw Kazekaze punch the ground, his first reaction was to rush him to the hospital. As the creator of The Eight Inner Gates Release, Tobirama understood this technique better than anyone! Every human body had eight inner gates that restricted chakra flow, but not everyone could unlock them.

Might Bai could only use The Eight Inner Gates because he had pushed his body beyond human limits— strengthening every muscle, organ, and nerve to withstand the strain! And even then, Might Bai couldn't prevent the damage The Eight Inner Gates caused. He could only minimize it. But Kazekaze was only seven years old! There was no way he had a body as tough as Might Bai's.

Gate of Closing alone could have ripped his muscles, tendons, and even damaged his internal organs! Tobirama was excited about Kazekaze's insane talent, but he was also deeply worried about his physical condition. No matter how gifted he was— Kazekaze was still his precious grandson. If given the choice, Tobirama would rather Kazekaze have no talent at all than see him injured. At that moment— Tobirama felt a deep sense of guilt.

'I'm not a good grandfather. Because of me, Kazekaze pushed himself too far and got hurt!'

However… Just as Tobirama was drowning in guilt, Kazekaze casually deactivated the Gate of Closing, straightening up as if nothing had happened. In his Gate of Closing state, Kazekaze's muscles and tendons had suffered damage— the pain had nearly knocked him unconscious. But the moment he closed the gate, his Regeneration Ability activated. Within two or three breaths, his muscles and tendons completely healed. As if he had never been injured at all! The pain faded away, disappearing entirely. Kazekaze was stunned.

The The Eight Inner Gates Release was a powerful taijutsu, but it was also a double-edged sword— it harmed both the enemy and the user. Before fighting Danzo, Kazekaze had mentally prepared himself for the damage. But he never expected his body to be this brokenly overpowered! Sure, he had Hashirama's Chakra— but chakra was chakra. Regeneration Ability was a completely different ability. They weren't supposed to be related. Excited, Kazekaze immediately checked his status panel.

Host: KazekazeStrength: 4Speed: 3Endurance: 6Abilities: Hashirama's Chakra Lv1, The Eight Inner Gates Release Lv5

There was no mention of Regeneration Ability. Which meant— this ability was inherited from his bloodline! It was Senju Hashirama's natural regeneration! Or… Maybe it was also influenced by his Uzumaki bloodline? Kazekaze couldn't contain his excitement. His body was only seven years old. No matter how much he trained, he couldn't surpass Might Bai's physical endurance in the short term. His original plan was simple— if he ever got something better from his Check-In System, He would drop The Eight Inner Gates immediately.

The damage was too severe to justify using it. But now… Why would I ever drop this? If he just kept using it, and adapted to the pain— wouldn't he become unstoppable?! No matter how much damage he took— his body would heal instantly. In just two or three breaths! It was as if The Eight Inner Gates was custom-made for him!

'Not only that… Even if I can't match Might Bai's endurance now, as long as I keep training… My body will naturally strengthen. Eventually, I'll reduce the damage from The Eight Inner Gates entirely! If my healing speed outpaces the damage— I'll be able to use The Eight Inner Gates freely!' Kazekaze's eyes sparkled with excitement.

This was just a theory, but there was no reason it wouldn't work. After all, in the original story, Tsunade healed from Susano'o attacks within seconds. And her technique was just a knockoff version of Hashirama's Regeneration Ability. Could The Eight Inner Gates really do more damage than Madara's Susano ? If not— then his theory was absolutely possible!

"Wait… Are you… okay?" Tobirama stared at Kazekaze in disbelief.

Where was the muscle tearing?

Where was the tendon damage?

Where was the crippling pain?

Why did this kid look completely fine?!

'What the hell went wrong?!' 

Kazekaze turned toward Tobirama, realizing what he was worried about.

"Oh, you mean the damage from The Eight Inner Gates?" He rolled his shoulders and stretched his arms.

"Yeah, that hurt like hell." Then he smiled. "But it's fine now."

Tobirama: "???"

'WHAT DO YOU MEAN 'IT'S FINE NOW'?! DO YOU THINK YOU'RE HASHIRAMA?! ARE YOU SAYING EVEN SEVERE INJURIES JUST HEAL ON THEIR OWN?!'

Wait… A terrifying thought entered Tobirama's mind. He stepped forward, grabbing Kazekaze's arm. He inspected it carefully. It was perfectly intact. No damage. No bruising. Nothing.

"You… inherited Hashirama's Regeneration Ability?!"

At this point, Tobirama had lost count of how many times Kazekaze had shocked him. All he knew was— He was shocked. Again. Not only did Kazekaze have insane talent, But he had also inherited Hashirama's broken bloodline abilities! Tobirama swallowed hard, staring at Kazekaze's young face. His eyes were wide, like he was staring at an alien from another world.

"You mastered The Eight Inner Gates and Senju Monstrous Strength…? Good lord, I almost believed you when you said you hadn't trained before. How many secrets are you hiding? Who taught you all this?!" Tobirama no longer believed Kazekaze's excuses. There was no way he had learned all this on his own. Hashirama must have secretly trained him!

'That bastard… He probably used a Wood Clone to sneak out of the village and train Kazekaze behind my back! That's the only explanation!'

Might Bai, meanwhile, was losing his mind.

"Lord Tobirama, wait— you mean Kazekaze-sama already mastered Senju Monstrous Strength too?!"

To him, even mastering Senju Monstrous Strength was absurd enough. Without years of training, it should have been impossible! But Kazekaze had learned both Monstrous Strength and The Eight Inner Gates.

'Are all Senju monsters?! And is Kazekaze the biggest monster of them all?!'

Kazekaze, however, had already predicted this reaction. So— He smiled innocently and dropped the ultimate bombshell.

"Oh, that? I just watched Might Bai open The Eight Inner Gates once and figured it out." Then he tilted his head. "Wait—don't tell me someone actually thinks The Eight Inner Gates is hard?"

Tobirama: "!!!"

Might Bai: "!!!"

Everyone: "?!?!?!?!"
