Chidori Complete

Chirp, chirp, chirp! Lightning flashed in Uchiha Yi's hand. His violent Lightning Release Chakra crackled like thousands of birds crying out at once.

Uchiha Yi gazed at the lightning in his hand, a faint smile touching his lips. It had taken him three months of work under Tsunade and Mito Uzumaki's guidance to develop Chidori.

"Is it finished?" Tsunade folded her arms and studied the lightning in Uchiha Yi's hand. Uchiha Mikoto, Kushina Uzumaki, and Nawaki looked curious too.

They had watched Uchiha Yi propose the theory, pore over the Senju Clan's extensive records on Lightning Release training, and complete the Ninjutsu with Tsunade and Mito Uzumaki's guidance.

"More or less." Uchiha Yi nodded. Then he burst forward at a speed far beyond what a Chunin could reach and easily pierced a dummy in the distance.

Only after he stopped did Uchiha Yi speak. "For me, the Ninjutsu is complete. But it'll be hard for others to learn.

"To attack with it, you have to rush toward your opponent at high speed. You might move so fast that you can't see the enemy clearly and leave yourself open to a counterattack. It needs the Sharingan to reach its full potential.

"But few members of the Uchiha Clan have a natural affinity for lightning. Most only have an affinity for fire.

"It's possible to develop a lightning affinity later, but it'll never match an innate one. They'd be better off studying fire."

"At least you succeeded, right? If you used that Ninjutsu on me, I'd probably die on the spot." Nawaki glanced at the ruined dummy and swallowed. "That's got to be as powerful as a B-rank Ninjutsu, right?"

"No. It's an A-rank Ninjutsu," Mito Uzumaki declared. She looked at Uchiha Yi with open admiration. "The best Ninjutsu is the one that suits you.

"And the same Ninjutsu can have very different effects in different hands.

"Take your Uchiha Clan's Fire Style: Majestic Destroyer Flame. In another Uchiha's hands, it's merely a Fire Release technique somewhat stronger than the Great Fireball. In Madara Uchiha's hands, it becomes so deadly that dozens of Ninja skilled in Water Release have to work together just to have a chance of stopping it.

"Your Ninjutsu takes Lightning Release Chakra Nature Transformation almost to its limit, with a touch of shape transformation as well. You can keep refining it. I think it has tremendous potential. One day, it might even rival the Raikage's Lightning Release Chakra Mode."

"Madara Uchiha's Fire Release takes dozens of Water Release specialists working together to stop?" Tsunade's curiosity about Madara Uchiha was piqued.

In private, Mito Uzumaki had said more than once that Uchiha Yi's talent was no less than Madara Uchiha's had been. But Tsunade knew little about Madara. She didn't even know how strong her own grandfather had really been. He was probably just somewhat stronger than Hiruzen Sarutobi and Tobirama Senju, right?

"Yes. Hashirama said Madara Uchiha's Mangekyō Sharingan Dōjutsu might enhance the power of his Ninjutsu. The techniques he used were stronger than an ordinary Ninja's." Mito Uzumaki sighed at the mention of Madara Uchiha.

Sometimes she wondered whether Tobirama Senju had been right to use certain means to prevent Madara Uchiha from becoming Hokage. If Madara hadn't left, would Hashirama still be alive? If Hashirama hadn't died, would Tobirama have survived too? Would the Uzumaki Clan have escaped destruction?

If they had followed Madara Uchiha's advice and unified the entire Shinobi World, would it truly have found peace?

Madara Uchiha had certainly done many wrong things, and he was a madman. But no one could deny his pursuit of peace.

"I see. It's hard to imagine how strong he was." Tsunade stepped forward and ruffled Uchiha Yi's hair. "Brat, you did well. Just what I'd expect from my student. Creating an A-rank Ninjutsu at six years old—that's one of a kind in the entire Shinobi World."

Uchiha Yi smiled bashfully. "Without your help and Grandma Mito's, I might not have figured it out even after five or six years on my own."

"You're a good kid!" Tsunade nodded in satisfaction. She hadn't gone to Hatake Sakumo for advice on Lightning Release Chakra Nature Transformation for nothing. The brat knew how to appreciate her efforts.

"Have you thought of a name for the Ninjutsu?" Mito Uzumaki grew more impressed with Uchiha Yi by the moment. It was a pity he was more than ten years too young. Otherwise, he might have made a fine grandson-in-law.

"Chidori. It sounds like a thousand birds chirping when I use it." Uchiha Yi had no intention of changing its name.

He didn't know whether Kakashi's Chidori was the same as his, or whether his matched the original. But Mito Uzumaki had recognized his Chidori, so his was the real thing.

"Chidori. A good name." Mito Uzumaki nodded approvingly. "Chidori it is!"

"What a shame. I don't have a lightning affinity, so I can't learn it at all." Nawaki clasped his hands behind his head, full of regret. Over the past three months, he and Uchiha Yi had gotten to know each other.

He had even challenged Uchiha Yi before, only to discover, much to his dismay, that he was no match for his "junior martial nephew," who was two years younger than him.

The loss had hit Nawaki hard. Luckily, he was an optimistic boy. If he couldn't beat Uchiha Yi now, he just had to train harder.

"Nawaki!" Tsunade gave her younger brother a helpless look. Chidori wasn't so easy to learn. Mastering that degree of Chakra Nature Transformation would put someone firmly at Chunin level, and even ordinary Chunin couldn't control it that well. Her foolish brother had a long way to go.

Even if Uchiha Yi taught Nawaki Chidori, Nawaki wouldn't learn it for years. He would be better off studying Second Grandfather's Water Release and Orochimaru's Earth Release. Those suited him best.

Why study Lightning Release when the right path is already in front of you?

"Now that you've developed Chidori, it's time for me to start teaching you Monstrous Strength. Are you ready?" Tsunade was determined to make sure Uchiha Yi learned it. Otherwise, wouldn't she look useless as his teacher?

She had also realized during their time together that although Uchiha Yi was an Uchiha, his physique was no worse than a Senju's. With his extraordinary Chakra control, he would have made a fine student for her even if he weren't an Uchiha.

Why bother with the Sharingan, Uchiha Yi? You'd be much better off learning Monstrous Strength from me.
