Toneri's floating castle in the heart of the Moon's inner sun was like nothing Naruto had ever seen before. He had visited a few castles in his youth, such as the haunted one in the Land of Honey and Kazehana Castle in the Land of Snow, but their architecture was completely different; Japanese-style rather than Gothic.
'Naruto… Naruto… Naruto…'
Upon hearing his name, Naruto stopped running and ground to a halt in the middle of a long corridor. Hearing his footsteps stop, Karin turned around and glanced at him.
"Did someone just call my name, ya know?" Naruto said, puzzled. "I could've sworn I heard Sakura-chan's voice…"
"Well, I certainly didn't, and we're the only ones here," Karin said in a huff. "Are you sure you didn't just imagine it?"
Karin hugged her chest, wiggling her entire body like a worm.
"Ooh, and now I'm getting onee-sama withdrawal symptoms too!" she crooned, running her hands up and down her curves. "Oh, onee-sama, how I miss youuu! I can almost smell your shampoo… kun, kun~!"
Naruto took a step back from his distant relative, a wary look on his face. He'd caught her skulking about his bedroom one time, with a jar filled with pink hairs.
'Naruto,' Sakura's anguished voice rang out in his mind. 'Naruto, help me!'
This time, Naruto was certain of it. Sakura was calling out to him, but how? Could it be…?
'You're not imagining things, brat,' Kurama said, intrigued. 'I can hear her voice too, but it's not a miracle of true love like you're thinking… it seems like she's managed to get her hands on some of that stupid octopus's chakra…'
'Yo, 'sup, Kurama,' said the Eight-Tails. 'How's it hanging?'
Naruto put his hands to his mouth.
"SAKURA-CHAN, WHERE ARE YOU!" he yelled at the top of his lungs, startling Karin, who was still doing her wiggle dance. "I'M RIGHT HERE, YA KNOW!"
Karin sighed.
"Listen, idiot, this entire artificial sun is a sensory barrier, which means there's no way to send signals in or out," she said impatiently. "Onee-sama should still be on Earth, and even if she were here on the Moon with us, there's no way she could sense our chakra, let alone hear you shouting."
No sooner had those words escaped her lips than a tremor rippled across space-time.
Space itself shimmered and warped above Naruto's head, and as he looked up to examine the anomaly, two enormous globes of flesh suddenly filled his entire field of vision. Without warning, Sakura fell out of thin air on top of him, smothering his face with her enormous breasts as they toppled to the ground together.
Karin gaped at them in shock.
"ONEE-SAMA, WHERE ARE YOU!" she yelled, waving her arms in the air. "I'M RIGHT HERE, YA KNOW!"
Unfortunately, the heavens had no more pink-haired, busty chicks to bestow upon her.
"Gah!" Naruto gasped for air as he prised Sakura away from him. He inched his way out from under her body, freeing his nose and his mouth from her soft bust. "Sakura-chan, since when can you teleport!?"
He could feel Sakura's entire body trembling through her jiggly bosom. She was hugging his chest tightly, as if she feared that he might disappear if she let go.
"I was so scared that I would never see you guys ever again…" she said shakily. "I didn't know what I would do if I lost you…"
Naruto brushed fingers through her long, pink hair.
Even though she was strong enough to snap his spine without even using chakra, Sakura seemed so delicate, her body so soft and vulnerable. Her body was covered in bruises and bloody scrapes, her dress was torn and her hair was dishevelled… just what had happened?
"Thank goodness I made it back…" Sakura said softly as she stared down at him, her eyes moist.
Naruto stared at her trembling lips… and without hesitation, he kissed her.
"Mmh…"
The tremors running through her body slowly came to a stop.
"Mhh… Naruto, it's the enemy," Sakura gasped as their lips separated. "He's here, on the moon!"
BOOM!
Without warning, a bone-rattling shockwave swept through the castle, blowing out the stained-glass windows lining the corridor. Naruto, Sakura and Karin rushed to the windows and looked outside. Twin cyan comets traced wide arcs across the yellow sky of the artificial sun, meeting again and again in cataclysmic clashes that sent shockwaves rippling through the air.
"WHERE IS IT?" Toneri roared. "WHERE IS MY GIANT TENSEIGAN!"
"Somewhere safe," Hinata's voice echoed through the inner sun. "Somewhere it'll never be used to hurt others ever again."
Only a descendant of Hamura could touch the Energy Vessel, so upon noticing its disappearance, Toneri had made a beeline for Hinata's chakra signature, completely ignoring Tenten's.
"So that's why the Moon Tunnel collapsed," Sakura realised. "Without its power source, the Moon's infrastructure started failing!"
Naruto quickly re-entered Six Paths Sage Mode and created a large surfboard from his Truth-Seeking Orbs for the three of them to ride. Together, they whistled towards the mid-air battlefield, which was littered with floating stone fragments from the islands Hinata and Toneri had destroyed during their battle.
"Chibaku Tensei!"
Just to be safe, Sakura poured the entirety of the chakra pill's energy stores into the gravity bomb she threw at Toneri's back. She didn't want a repeat of last time, where she'd accidentally shunted herself into another dimension by running out of space-time cannon chakra mid-jump.
"GET HIS EYES, THEY'RE HANABI'S!" Sakura shouted as Toneri froze on the spot. "HURRY, I WON'T BE ABLE TO HOLD HIM MUCH LONGER!"
A miniature black hole began to form, with him as its core…
"Damn you… Uchiha!" Toneri roared. "How… dare you!"
Since Sakura was using lower-ranked chakra to hold him in a gravity field, she naturally had to use a metric tonne of it to barely restrain him, achieving a qualitative change through a quantitative increase to overpower his superior Six Paths chakra.
"G-got it!"
Hinata quickly swooped down and jammed her fingers into Toneri's eye sockets, prying out his eyeballs, and as soon as the optic nerve was severed, his cyan chakra cloak vanished. However, Hinata herself was still caught in the gravity well…
"S-Sakura!" she gasped. "I… I can't get out!"
For a second, Sakura was tempted to release her jutsu. Hinata was more powerful than her, a danger to the village…
"Naruto, help her out!" Sakura cried out. "The moment my jutsu ends, anything within its range will be banished to another dimension!"
A long, golden chakra arm stretched out from Naruto's back and plucked Hinata from the gravity well's influence. The moment she was out of range, Sakura finally released her jutsu, and Toneri vanished with a loud pop as air rushed in to fill the void he had left behind.
He was now another moon's problem.
