Ultra-Big Ball Rasengan

After teaching Kushina for a while, Eiji said he had taught her everything he could. The rest was up to her own efforts, which left her annoyed.

Ugh, my future "good partner" is such a blockhead!

Eiji had something else to do. He wanted to see how powerful a Rasengan he could make with his current Chakra reserves.

He darted into the forest a short distance away, where Kushina and Minato could still see him.

He extended an arm and began gathering Chakra. With the precise control of his Six Eyes, even that much Chakra wouldn't make the Rasengan run wild. He watched the ball in his hand grow larger and larger until it became a massive sphere of energy one meter across!

Uh...

That seemed to be his current limit. He could only launch around ten Rasengans of that size before his Chakra was nearly exhausted.

It showed how different Chakra and Cursed Energy were. An Azure of the same scale would have taken hardly any effort, and he could have kept up an endless bombardment. He couldn't do that with Rasengan.

The Six Eyes could compress Cursed Energy consumption so efficiently that Jujutsu cost almost nothing to cast. Cursed Energy came from negative emotions and was hard to quantify; it was an abstract concept. Ninjutsu, however, consumed Chakra.

Chakra was a form of energy. No matter how much he compressed it, he could only minimize consumption, not reduce it to almost zero.

Even so, compressing his Chakra usage let him fire off a few extra Rasengans. That was better than nothing.

If activating the Satoru Gojo Template hadn't given him a substantial boost in Chakra, he couldn't have managed even this much.

Looking at the increasingly dangerous Rasengan in his hand, Eiji couldn't resist testing the Ultra-Big Ball Rasengan's power.

Minato and Kushina, still practicing in the distance, saw it too. The Balloon in Minato's hand burst with a pop, splashing water all over him.

Was he even human!?

Minato swallowed. He couldn't imagine how devastating that thing would be if it came down!

Kushina stared, dumbfounded. The difference was this huge!? Could Tsunade take a hit from that?

Eiji figured that now he'd made it, taking it back wasn't realistic. He decided to launch it and see what happened.

He leaped high into the air and, imitating Naruto, swung the Rasengan down onto a massive Rock a full ten meters tall!

In an instant, the azure sphere of Chakra shredded the Rock and slammed straight into the ground!

BOOM! BOOM! BOOM! BOOM! BOOM!

The ground shook as if an earthquake had struck. Minato and Kushina nearly lost their footing.

A fierce gust sent Kushina's red hair whipping wildly. Minato raised an arm to shield his face from flying sand and stones.

Wood Chips, shattered stone, and soil shot into the sky, then rained down in every direction!

A thick cloud of dust billowed up, swallowing Eiji from sight!

Only after the vast, violent Chakra had dissipated did Minato and Kushina dare approach the blast site. Eiji emerged from the dust, flexing his wrist, his expression calm.

Noticing that Eiji didn't have a speck of dust on him, Minato was impressed. Eiji had even kept up his image through all that. Minato would have to do the same next time he showed off.

Then he took in the destruction.

The Ultra-Big Ball Rasengan had carved out a massive Semicircular Crater ten meters across.

The Chakra had been so powerful that the shock wave alone had blasted a huge hole in the ground.

Trees all around leaned at odd angles, and rubble lay scattered everywhere. One word summed up the scene: terrifying!

Minato figured anyone hit by that would be blown to pieces, no matter how strong they were.

"Eiji, what's that move called?"

"Hmm... Ultra-Big Ball Rasengan."

That name was way too plain! Minato thought it didn't do such destructive power justice. If he got to name it...

It would have to be Ultra-Big Ball Ultimate Peerless Whirling Rasengan: Form Zero!

A flurry of footsteps sounded in the distance. Eiji shrugged. Now they were in trouble.

"Ah, the Anbu Ninja must have come to investigate. We're in trouble."

"Huh? What?"

Minato was still trying to process that when four or five masked Ninja surrounded the three of them.

"We're Anbu Ninja. What caused that huge explosion? Did Ninja from an enemy nation infiltrate the village?"

The Cat Mask Ninja leading them took in the devastation. It never occurred to him that these three children had caused it; he assumed enemy Ninja had developed some terrifying bomb.

"No enemy Ninja. I was researching a new Ninjutsu and accidentally blew up part of the forest."

"What!?"

The Anbu Ninja looked from the crater to Eiji, then exchanged glances.

"What Ninjutsu?"

"A new Ninjutsu I developed. It's called Rasengan."

This kid could wipe the floor with me. How did that make any sense?

He had intended to take Eiji to the Hokage Building to make a report, but then he noticed Kushina Uzumaki beside him. Realizing the matter might involve Mito Uzumaki, he hesitated.

After all, going to the Hokage Building might mean handing over the Ninjutsu. Lady Mito might be displeased if she found out, and he couldn't afford to offend her.

"Let's do this. It won't be safe here for long, so you should head home. I'll report this to Lord Third Hokage."

Eiji and the others had no choice but to cut their training short.

Minato didn't mind. He had gained plenty from the session.

He could practice Rasengan at home. All he needed was a Balloon and water; he could learn an incredible technique at almost no cost.

Kushina was satisfied too. She had grown closer to Eiji and watched him take another step forward in strength.

Earlier, in the Hokage's Office.

"Danzo, you bastard! Is there anyone more shameless than you? You snatched the man who attacked a fellow Ninja of this village, then crushed his head! You're disgusting!"

Tsunade jabbed a finger toward Danzo's nose as she berated him. The news from the Yamanaka Clan had nearly made her explode with rage.

Last night, while they were extracting information from Shimura Shio's mind, a group of masked people had snatched him away.

When the pursuers caught up, the group dumped Shio's corpse—but his head was gone!

Tsunade didn't need to think to know who was behind it!

The infuriating part was that Shimura Danzō had retorted that she had no evidence and shouldn't make false accusations. She was so furious she'd started cursing him out.

Even Utatane Koharu and Mitokado Homura, standing nearby, couldn't stomach it. They thought Danzo had handled the whole thing disgracefully. If he wanted to destroy the evidence, couldn't he at least be subtle about it? Did he have to be so blatant?
