Okinawa Dungeon—-Final Floor:
As quick as lightning, the old man and the dragon continued their fierce duel. The surviving dragons backed away, unable to withstand the force.
"PERISH!"
Raizen's sword cut through the air like a bullet, aiming right for Omariro's head.
"Jugen-Sōunsha: Cursed Movement!"
Omariro vanished, reappearing over Raizen's head.
"Still maintaining your speed," Raizen remarked. "How long until it drops?"
A lightning-charged claw tried to grab Omariro, but he fired his bow at it, blowing it clean off.
〈Boss HP: 1,500% → 1,200%〉
Raizen stuck out his arm, regenerating his claw.
〈Boss HP: 1,200% → 1,500%〉
"Let us continue."
As fast as lightning, Raizen appeared next to Omariro, opening his mouth and firing a barrage of electricity from it.
BOOM.
The blast hit Omariro, slamming him into the ground and searing through his entire body, damaging his clothes.
"Smell bad," Omariro commented. "Clothes broke."
Raizen descended, landing in front of Omariro. "That blast was enough to kill a human a thousand times over. Yet you're still standing. How?"
Omariro ripped off his top, exposing his frail body. Raizen narrowed his eyes as the wounds slowly began to heal.
"I get it now…" Raizen realized. "You can't die easily, can you? You possess all seven classes, but you've never used Kaiseisha in your life. It must be a passive ability, isn't it?"
Omariro picked up his fallen staff. "Dragon smart."
Raizen chuckled. "But it seems you can age just like any mortal. So it's only a matter of time before you fall apart. Once I'm done with you, I'll slaughter those wretches you call your students."
Omariro's eyes began to glow. "Dragon can try."
His hair began to stick up. "Jugen-Kaiseisha: Cursed Immortality."
His body appeared to age even more, to Raizen's surprise.
"What are you—-?"
Faster than before, Omariro lunged at the dragon, sending him into the air with a bat of his staff.
BOOM.
Raizen fell into a temple, destroying it. Omariro dropped down, his sword in hand. Raizen blasted the temple's remains back with a powerful shockwave, sending them floating in the air.
"What have you done, Nyugawa?"
Omariro's body became coated in armor. "Kaiseisha counters Oath. Body age. Power grows."
Raizen's wings beat. "You are wise, old man. But wisdom cannot beat the Dungeon!"
〈Rule: Die〉
A powerful lightning bolt struck Omariro from above, and what was left was nothing more than a pile of ash.
"Goodbye, Omariro Nyugawa."
Raizen turned towards the moon-lit trapdoor. "Now, for the children."
Raizen's fist smashed the ground surrounding the trapdoor, and he prepared to enter. "The moon shall remain caged."
As he put one foot inside, he felt a pull on his tail.
"Hmm—-?"
"Bad dragon."
Raizen turned around, only to find Omariro standing there, fully intact.
"WHAT?"
Omariro spun Raizen around by his tail, smashing him into buildings before letting go. The dragon blinked a few times, in disbelief. "I saw you burn to ash! The Rule made it so!"
"Rule does not get defied," Omariro stated. "Rule gets broken. Dragon next."
Raizen waved his hand, and the remnants of his army took to his side. "I'd love to see you try. Children, fuse!"
His children all attached themselves to him, and with a glowing red light, Raizen began to grow, shift, and change.
What stood before Omariro was no longer Raizen. It was a massive black and crimson dragon with three heads, six wings, and eight arms. It was coated in armor and had two massive greatswords in its hands.
〈Rule: Defeat *Raimei Danjon no Kōryūshin — Raizen.*〉
〈Boss HP: 1,500% → 20,000%〉
Raizen leaned down, his voice deep and ominous. "Congratulations, mortal. You've earned the wrath of Kōryūshin."
〈Domain Effect: Oathkeeper—-Crimson Reign. Description: Every *10s* Raizen will be able to unleash *Crimson Thunder*, which will summon *Furious Dragonsbanes* that deal 20,000% bonus damage.〉
"Do not hold back anymore, Omariro Nyugawa. The Endless is watching."
In the blink of an eye, Raizen struck. His blades narrowly missed Omariro, who teleported out of the way and fired a barrage of arrows at Raizen.
〈Boss HP: 20,000% → 15,000%〉
Raizen laughed. "That's better."
〈*Furious Dragonsbanes* in effect.〉
Two large glowing dragon constructs appeared, swooping down toward Omariro.
"Jugen-Metsusha: Obliterate!"
With a clap of his hands, the dragons disappeared. Raizen responded by kicking Omariro into the air, flying after him.
BOOM. BOOM. BOOM.
With Raizen's attacks growing more furious and uncontrollable, Omariro narrowly avoided and blocked them.
"CHILDREN!" Raizen roared. "LEND ME YOUR STRENGTH! I WILL NOT FAIL YOU!"
As if hearing his call, more Furious Dragonsbanes formed, blasting Omariro with crimson lightning.
"Jugen-Tōshi: Seijin Rangeki!"
Omariro's blades met the lightning, creating a massive explosion of thunder and gold.
"Disappear," Raizen ordered.
He lunged at Omariro, but Omariro landed on the ground, running at high speed. Raizen dropped and followed behind, shooting lightning from his mouth.
"Jugen-Kōbisha: Forbidden Prison!"
Omariro's seal swallowed up the lightning, and Raizen began unleashing a flurry of strikes, which Omariro deflected.
"This man," Raizen thought. "So old, so frail, yet so strong. This is a mortal worth my time."
More blades formed in his hands. "No, he's no mortal…"
Raizen kept up as Omariro kept running, not even looking behind him.
"…he's a monster."
Raizen swung his blade again, but Omariro blocked with his arm, the blade bouncing off as if it hit steel.
Omariro turned the corner, with the dragon hot on his heels. Raizen unleashed a wave of crimson lightning, but Omariro teleported between it.
"Why run? Stand tall and fight!"
Omariro looked back, and in the next second, he teleported above Raizen, slamming his head into the ground and dragging him along.
〈Boss HP: 15,000% → 13,500%〉
A Furious Dragonsbane formed and knocked Omariro off, taking his arm with it.
"You're cornered," Raizen declared. "This is where we make our final stand."
Omariro's arm regenerated, as he grabbed his back. "Bad back. Finish you quickly."
Raizen lifted his blades. "Don't worry. Your back will be the least of your problems. Any final words?"
Omariro cracked his back before pointing his blade at Raizen. "Dragon blind."
"Hmm—-?"
Raizen's eyes widened and he turned around, where a blast of moonlight hit him smack in the face.
〈Boss HP: 13,500% → 12,000%〉
"Hehe! Face shot!"
Omariro watched as a barefoot girl floated and landed on the ground, with Han, Rika, and Zaria behind her.
"Sir!" Zaria called out. "We're back!"
"We brought help!" Han announced.
"And she may or may not be a ghost!" Rika added.
Han and Zaria turned and stared at her. "What?"
Rei skipped over to Omariro, taking his arm and examining it. "You're the strongest? So old! So short! So amazing!"
"Girl touching," Omariro stated. "Stop."
She grabbed one of his dreadlocks, sniffing it. "Ooh, smells like wine!"
Omariro teleported out of her way, and she tripped and fell over. "Gah! Hehe! Awesome!"
As the others joined them, Raizen recovered, his eyes blazing with fury.
"Rei…"
She turned to Raizen, waving and humming. "Hi, Raizen! Finally free!"
"Go back into your cage."
She wiggled her finger, giggling. "Nope! No! Nada! Nah!"
Raizen's claws extended. "Pitiful girl. Don't make me ask again."
Rei put her fists up, jumping up and down. "Ooh! Are we throwing hands? Me first!"
The party stared at her.
"She's odd," Han whispered.
"Definitely," Zaria agreed.
"She is wearing no shoes," Rika pointed out.
Raizen opened his mouth. "I'll deal with you first."
Lightning fired out of his mouth, and Rei put up a hand, a smirk on her face.
"Jugen-Mahōshi: Tsuki no Megenka!"
A beam of moonlight fired from her hand, striking the lightning beam and hitting Raizen in the chest.
〈Error: Oathkeeper Connection *Severed.*〉
"Yes!" Zaria cheered. "Show 'em, lady!"
Raizen stabbed one of his blades into the ground. "You dare turn against your master! I'll have your head for this, girl!"
He flung one of his blades at her, but she giggled.
"Jugen-Mahōshi: Mujin no Yoru no Mikazuki!"
A large moon crest formed in the air, and with a wave of her arm, the crest deflected the blade. Raizen roared, lightning raining down on the party from the sky, but Rei put up two fingers.
"Jugen-Mahōshi: Gekkō no Gokō!"
A barrier of moonlight formed around the party, protecting them from the lightning. Omariro looked around before turning his attention back to Rei.
"Girl strong."
She blushed. "Aww, thanks!"
Raizen cut through the shield with a slice of his blade, but Omariro stopped it.
"Dragon weakened. Now dragon falls."
Raizen's wings extended, and lightning bindings trapped everyone except for Zaria and Omariro, who grabbed Zaria and pulled her out of the way.
"If you think I need that Oath to wipe you all off the face of this planet, you may not be as wise as I thought."
"What do we do, sir?" Zaria asked.
"Get on back," Omariro ordered.
Zaria's face turned red. "Huh?"
"Get on back. We slay dragon."
Zaria broke into a wide-eyed smile. "Okay!"
She hopped on Omariro's back as Raizen watched. "Hmph. Pitiful."
Zaria summoned her spear. "What's the plan, sir?"
"Throw spear. No matter what."
"Throw it?"
"Throw."
Raizen slammed the ground where they stood, but Omariro was already gone.
"Jugen-Tōshi: Cursed Spear!"
From his right, a spear struck Raizen in the eye.
〈Boss HP: 12,000% → 11,999%〉
Raizen reflexively closed his eye. "Argh! Show yourselves!"
Omariro rammed into the dragon from the right, slicing a deep gash into his chest.
〈Boss HP: 11,999% → 9,000%〉
"Nice!" Zaria said, pumping her fist. "That got him, sir!"
Raizen quickly regained himself and batted them out of the air, but Omariro landed on his feet, Zaria still on his back.
"His sword's coming, sir!"
Raizen repeatedly slammed his sword into the ground, lightning bursting upward from the ground. Omariro nimbly dodged the attacks as Zaria prepared another spear.
"Locked-on! Eat steel!"
She threw it, but Raizen caught it. As soon as he did, Zaria flung another spear at him, striking him in the left eye.
"You seal your fate, girl!"
Omariro sliced Raizen's arm.
〈Boss HP: 9,000% → 8,000%〉
"You saw that, sir? I nailed 'em!"
Omariro gave her a nod. "Good."
Raizen's bindings on the other party members broke, and he quickly scooped up Omariro and teleported away.
"Sir!" Zaria exclaimed.
Han and Rika quickly ran over.
"Where'd they go?" Rika asked.
"I don't know!" Zaria replied.
"Maybe I can use my cube to track them!" Han proposed.
"No need!" Rei giggled. "They're right there!"
Rei pointed far in the distance, where thunder and lightning shot out from a gigantic dragon temple.
Temple of the Dragonsbane—-
〈Rule: Only *One* Can Survive.〉
Raizen dropped Omariro, and a barrier of lightning surrounded the temple.
"Your little trick was clever," Raizen praised. "The girl's spear still affects my vision."
"Girl capable," Omariro said. "All are."
"Maybe so. But without you, they are nothing more than fodder. The Rule is in place. Only one of us leaves here alive."
Omariro shed his armor, his blade in hand. "Let it be done."
The two engaged in one final clash, red and gold emitting from their bodies. Omariro and Raizen kept up with each other's speed, their attacks growing more and more powerful.
"This fight!" Raizen yelled. "Is worthy of death!"
Omariro leapt over Raizen's sword and formed his arrow, firing into Raizen's mouth.
〈Boss HP: 8,000% → 4,000%〉
Raizen's claw lashed out, slashing Omariro's face and blinding him.
"Now we both see nothing," Raizen stated.
"Yes," Omariro murmured. "Nothing."
Without his vision, Omariro listened closely, hearing the crackling sound of thunder as a bolt nearly struck his shoulder.
"Jugen-Sōunsha!"
Omariro quickly got out of the way, firing another arrow at Raizen.
〈Boss HP: 4,000% → 2,000%〉
Raizen kicked him, sending him sliding back. Omariro formed his blade, eyes swollen shut.
"You still hold back, Nyugawa," Raizen taunted. "Maybe this will show you."
〈Boss HP: 2,000% → 20,000%〉
〈Defeat Raizen in *1* Move to Win.〉
"Now do you see? Do you understand? You cannot defy the dungeon!"
"No," Omariro agreed. "You break. You surpass."
Omariro's blade shifted into a golden circular weapon with four different blades at each corner. It began spinning faster than Raizen could track.
"Jugen-Tōshi: Mugengan no Ōgonjin!"
The blade sliced through Raizen's body, cleaving him in half.
〈Boss HP: 20,000% → 0%〉
Raizen fell to the ground.
"Ahh, there it is. The Legend."
His top half looked at Omariro, who approached. "You could have ended the fight…anytime…why draw it out?"
"Bad for kids," Omariro answered. "Need growth."
"On that…we agree. Congratulations. You've…cleared the dungeon."
Raizen's body began to shake. "One more thing, Nyugawa. Remember my name…you'll hear it…again…"
"…Raishō Dragonsbane…Dragon of Thunder."
And with a burst of lightning, he disappeared.
"Raishō…" Omariro thought. "Strong."
