The knock came at four in the morning.
Hanekawa's eyes snapped open—a habit from his previous life—and he was out of the tent before the young chunin could knock again.
"Is the teacher awake?" the messenger asked nervously.
"I'll get her," Hanekawa said, already moving toward Tsunade's tent.
He found her sprawled across her bedroll, still in yesterday's clothes, golden hair scattered everywhere like she'd wrestled it in her sleep. She yawned as he entered, stretching with the kind of unselfconscious ease that came from being one of the strongest people alive.
Worth the early wake-up call, he thought, then immediately felt like an idiot.
Tsunade noticed his stare and smirked. "What?"
"You're beautiful," he said, deciding honesty was simpler than whatever excuse his brain was cooking up.
She blinked, actually caught off-guard. For a moment, something soft flickered across her face before she flicked his forehead hard enough to make him see stars.
"Don't waste time," she said, already moving toward the exit. "We've got a war to win."

Twenty-eight ninjas assembled in the pre-dawn darkness—seven teams, mostly jonin, all hand-picked for a sneak attack on the Hidden Mist stronghold. Tsunade stood before them like a general from some old war movie, except she actually looked like she could punch through a mountain.
Because she could.
"We move fast, we hit hard, we win," she announced. "After that, we feast."
The ninjas cheered. Hanekawa was already thinking about the approach when they reached the beach.
"I have an idea," he said, studying the distant island.
Tsunade raised an eyebrow. "Let's hear it."
"Water Style: Great Explosion Water Wave. I create a giant wave, you all ride it in. Sneak attack they'll never see coming."
The silence that followed was deafening.
"That's not a sneak attack," Tsunade said slowly. "That's a declaration of war with special effects."
Right. Probably should have thought that through. "Why not? They won't expect it."
"Because you're the only person in the ninja world insane enough to try it," she said, but she was already grinning. "Let's do it."

Hanekawa took a breath, gathered his chakra, and unleashed it.
The ocean responded like it had been waiting for permission. Waves rose—ten meters, fifteen, twenty—a moving wall of water that caught the morning light and turned it into something between a tsunami and a natural disaster.
The Mist Village ninjas spotted it halfway across. Their alarm bells were still ringing when the wave hit.
The impact was catastrophic. Genin and chunin who couldn't react fast enough got swept away. The senior ninjas threw up barriers—water walls, earth walls, desperate improvisation—but the damage was already done.
Tsunade landed in the middle of their formation and kicked.
The ground cracked. Gravel became shrapnel. A dozen Mist ninjas flew backward, bleeding before they hit the ground.
The rest of Konoha and Hidden Sand's forces poured in behind her, and what had been a stronghold became a slaughterhouse.
Hanekawa was already moving when he felt the spike of chakra. Lightning formed in his hands—not the crude version from before, but something refined, controlled, dangerous.
A figure materialized in front of him, and Hanekawa recognized him from Tsunade's briefing: Mangetsu Hozuki. White hair, young face, the kind of talent that made other prodigies nervous.
"You're Hanekawa," Mangetsu said. It wasn't a question.
"I am," Hanekawa replied. "Heard you were looking for me."
Mangetsu's eyes widened slightly—apparently he hadn't expected to be that famous—but he recovered fast. "The Seven Ninja Swords. Where are they?"
"Safe," Hanekawa said.
Mangetsu moved.
One second he was ten feet away. The next, his fist was inches from Hanekawa's face, muscles bulging with the Hozuki clan's signature technique—the Bold Water Arm. The air itself seemed to scream.
Hanekawa punched back.
Their fists collided, and Mangetsu's eyes went wide. The force traveled up his arms, and he flew backward like someone had tied a rope around his waist and yanked.
Not fully grown yet, Hanekawa thought, watching him struggle to his feet. And he's relying too much on swordsmanship.
Mangetsu drew two blades—flat, wicked-looking things—and came in again. This time he was faster, more controlled, both swords flashing in a deadly pattern.
Hanekawa drew the Thunder and Fire Sword and met him halfway.
The blades sang as they clashed. Mangetsu was good—genuinely good—but he was also fighting someone who'd spent the last few years learning every fighting style he could get his hands on.
Hanekawa shifted into Leaf Style, his movements becoming fluid, unpredictable. Mangetsu's eyes couldn't track the sword anymore, and that's when Hanekawa hit him with a genjutsu.
Just a simple one. Just enough to freeze him for a heartbeat.
It was all he needed.
The Thunder and Fire Sword came up, and Mangetsu barely transformed in time, his body becoming liquid water just as the blade would have cut through him.
Smart, Hanekawa thought. But not smart enough.
He let the electricity flow.
Chidori Flare erupted from his body, lightning spreading in all directions like a second sun. Mangetsu's scream was short and sharp before he collapsed, smoking and unconscious.
Hanekawa sealed his limbs with a quick jutsu—couldn't have him waking up and water-transforming his way out of captivity—and turned back to the battle.
It was already over.
Tsunade was standing in the middle of the courtyard, not even breathing hard, while the last of the Mist Village ninjas either lay on the ground or were running for their lives. The Hidden Sand ninjas were already moving through the stronghold, securing supplies and prisoners.
"That him?" Tsunade asked, glancing at Mangetsu's unconscious form.
"Yeah."
"How strong?"
"Best of his generation," Hanekawa said. "But he's not fully grown yet."
Tsunade smiled. "Neither are you, technically."
"I think we stopped being peers about three years ago," Hanekawa said.
"Don't get cocky," she warned, but she was laughing. "Stay sharp. Yagura will bring reinforcements, and we need to be gone before he arrives."
They were back at base camp within the hour, moving fast enough that by the time the Mizukage and his forces reached the island, there was nothing left but bodies and scorch marks.

That night, as the camp celebrated their victory, Hanekawa sat outside Mangetsu's tent—the prisoner was secured, sealed, and unconscious—and thought about what he'd learned.
The water transformation technique was going to be useful. The Hozuki clan's methods were different from standard Water Style, more organic somehow, like they were teaching the water to think.
Another entry waiting to be unlocked, he thought, watching the stars.
Tsunade found him there an hour later, sitting down beside him with a sake cup in hand.
"Thinking about your new student?" she asked.
"Thinking about how many jutsu are still out there," he said. "How many I haven't learned yet."
She took a drink. "You'll get there. You've got time."
That's what I'm afraid of, he thought, but he didn't say it out loud.
Instead, he leaned back and watched the sky, while Tsunade drank her sake and pretended not to notice when he smiled.
