"Big Ball Rasengan!"
A sphere of violently spinning chakra roared to life in Ryuuto's palm, the kind of move that made sane villains run and stupid ones cry. The swirling blue mass lit up the ruins, and even the corner of Mephistopheles' eye twitched. Shadows burst from his fingertips as he flooded the air with dark energy.
"You showed up at the perfect moment, brat. This time, I'm ripping out your soul and tossing it into hell myself!"
His sneer twisted into something monstrous. Two claw-like fingers, glowing with infernal magic, shot toward Ryuuto's eyes.
The clash detonated through the battlefield like a hurricane. Shockwaves blasted outward, forcing Quicksilver and the others to retreat. Wolverine grunted, scooping the Blackheart demon out of a shattered wall and slamming him somewhere less inconvenient.
Every gaze locked onto Ryuuto and Mephistopheles. Everyone knew it. No plot twists left. Whoever won here wrote the ending.
"Purgatory?" Ryuuto's expression sharpened. "Cute. Here, let me show you the deluxe version."
Mangekyo Sharingan — Tsukuyomi.
The world warped. Mephistopheles' eyes widened as the illusion swallowed him, dragging him into a nightmare so heavy even a demon god's magic faltered.
"You little rat!" he snarled, struggling. "You always pull some ridiculous trick!"
He shook violently, finally snapping out of the illusion through brute will alone. Hatred burned in his gaze.
"But that's all you've got! You can't kill me!"
Too bad for him, because by then Ryuuto's Big Ball Rasengan was already smashing into his energy shield. Mephistopheles' patience snapped. He dropped his defenses, letting the Rasengan hit him full-on just so he could claw directly for Ryuuto's throat.
Pain twisted his face. Muscles bulged. He lunged with murder in his soul.
Quicksilver practically jumped. "Yes! Do it! Kill that kid already!"
Too bad for him.
Mephistopheles' hand closed around… water.
A splash drenched his face.
Ryuuto's body collapsed into a puddle.
"Substitution Technique, genius," Ryuuto muttered from behind Wolverine. "Try to keep up."
"Wolverine, hold Tony. I'll handle healing!"
"Go," Logan snapped.
Ryuuto pressed glowing chakra-coated hands to Tony's injuries. The medical ninjutsu from Tsunade's data hit like warm lightning.
Tony sucked in a breath and opened his eyes. "Ryuuto… thanks. Seriously. That guy is a nightmare."
"We're brothers," Ryuuto said, squeezing his hand once before yanking it back. "Let me finish the job."
A dripping, furious Mephistopheles stomped across the rubble, steam practically rising off his rage. "You healed the metal tin can? Fine. Then you can all die together!"
He charged.
Blackheart regenerated a fresh clawed arm and shrieked, rushing Wolverine and Tony again.
Wolverine stepped up. "Kid, finish the healing. I'll hold them—"
"It's fine. I've got insurance."
Summoning Technique.
Two scrolls unfurled in a blur. Chakra flashed.
Katsuyu materialized in a swirl of mist.
Saru, the ape king, slammed down beside her, confused and mildly offended at existing in this mess.
"Katsuyu, medical support. Saru, with me."
No time wasted. Ryuuto sprinted forward, King Kong Staff already forming in his grip.
Blackheart leapt, screeching. "You think you can stop—"
"Dude, I broke your arm earlier by accident," Ryuuto said. "Don't embarrass yourself."
He flicked through seals.
Earth Style: Great Earth Flow River!
The ground beneath Blackheart liquefied, turning into a roaring mudslide. The demon faceplanted so hard even Wolverine winced. Mud packed into his nostrils like stuffing.
On the other side, Saru clashed with Mephistopheles. A beam of dark death-light scorched half his fur to charcoal.
Saru howled. "Kid! Everything hurts!"
"I've got you."
Ryuuto snapped his fingers.
Summoning Transformation – King Kong Ruyi!
The staff expanded, humming with power.
"Let's pay him back."
Ryuuto rocketed forward, staff raised high.
Mephistopheles sneered, dark aura swirling around him like a nest of vipers. "Then look at my newest trick."
He tore open the ground.
Red-eyed demons erupted from the abyss, screeching, snarling, hungry.
Even Saru muttered, "They look strong and… gross."
Ryuuto cracked his neck. "Relax. Young master's got this."
The first demon lunged.
Ryuuto swung.
The King Kong Staff slammed into the demon's skull, obliterating a horn and sending the creature flying.
More shrieks rose from the abyss.
Ryuuto grinned, adrenaline flooding his veins.
"Round two, then. Let's dance."
