Hearthstone Teleportation!

"What is this?"

Kizaru stared at the oddly radiant stone in his hand, frowning as he tapped it lightly, confusion evident on his face.

Finn smirked, taking the stone back to inspect it. After a moment, he nodded. "Perfect. The authentication worked—this hearthstone is now tied exclusively to you, Uncle Kizaru. No one else can use it."

"What does it do, exactly?" Sengoku leaned forward, his curiosity piqued.

Even Garp wandered closer, squinting at the stone. "Grandson, it looks fancy, but what's its purpose? A new kind of weapon?"

Instead of answering directly, Finn turned to Kizaru with a sly grin. "Uncle Kizaru, how far can you travel from Naval Headquarters in a minute?"

Kizaru blinked, the question catching him off guard. "As far as light can reach, naturally."

"Good," Finn said, placing the hearthstone back into Kizaru's hand. "Take this, travel as far as you can at the speed of light, and wait for my call."

The room fell silent.

"Wait a second!" Kizaru narrowed his eyes suspiciously. "Marshal, you're not trying to blow me up, are you?"

Finn laughed, holding his hands up in mock innocence. "Why would I want to blow up one of my Admirals? Trust me, Uncle Kizaru, this is a test. Nothing more."

The room erupted in chuckles as the others chimed in.

"Stop complaining, Polusalino!" Akainu barked with a smirk. "Obey the marshal's orders."

"Yeah, don't be such a baby," Aokiji added, leaning back casually.

"Marshal Finn wouldn't harm you… unless absolutely necessary," Garp teased, earning a glare from Kizaru.

Realizing he had no allies in the room, Kizaru sighed dramatically. "Fine, fine. But if this thing explodes, you're paying for my dry cleaning."

With that, he vanished in a flash of light, soaring away from Naval Headquarters at unimaginable speed.

A minute later, Finn's transponder snail buzzed. He picked it up with a grin. "Uncle Kizaru, where are you now?"

"I'm somewhere over the ocean, Marshal," Kizaru's voice crackled back, a mix of irritation and boredom. "The wind's strong, and the signal's terrible. What now?"

"Hold the hearthstone to your forehead," Finn instructed. "Then think the words 'return to the city' while tapping it lightly."

Kizaru sighed. "You're really enjoying this, aren't you?"

But curiosity got the better of him. He followed the instructions, tapping the stone against his head while silently saying the words.

Back at Naval Headquarters, a bright magic circle appeared near the Hearthstone device.

In a flash of white light, Kizaru materialized, looking dazed.

"What just happened?" he muttered, glancing around. "Wait… how am I back here?"

"You used the hearthstone to teleport," Finn explained casually, grinning at the stunned expressions of everyone in the room.

"Teleport?" Kizaru blinked, his usual aloofness giving way to genuine amazement.

Finn nodded. "This device lets you instantly return to its location from anywhere in the world. Once activated, no matter the distance, you'll be transported here immediately."

The room erupted in gasps.

"This is incredible!" Sengoku exclaimed. "The strategic applications alone…"

Crane Vice Admiral added, "With this, our forces can operate independently without fear of being cut off. And in emergencies, reinforcements can arrive instantly."

Garp clapped his hands together. "Grandson, let me try it next!"

"One at a time!" Finn laughed as the room descended into excited chaos, everyone eager to test the hearthstone for themselves.

For once, the usually stoic Naval officers allowed themselves to dream of a brighter future, thanks to a little glowing stone and the vision of their marshal.
