The Legendary Ghost Hunter

"Raiju. It's your turn."

Grey thunderclouds began converging above above the courtyard, nearly blocking the moonlight. The Lunatic spun around, confused, wondering what the hell was going on. The Ghost Hunters and Ghosts, however, were too busy fighting one another to notice.

That is, until this happened.

"ROOAAAR!"

With an ear-splitting bellow, Raiju leaped out of Finn's body in a shimmer of light, unleashing a powerful shockwave of energy all around it as it landed on the concrete ground and sent fractures outbounds.

BOOM!

The ground shook as several bolts of powerful blue lightning struck down from above, zapping all of the Phantoms and Wraiths to death instantly. Even the ones that were invisible could not escape their fate, and were reduced to nothing but ashes in the mere blink of an eye.

"Agh..." Raiju groaned deeply, shaking its furry body a bit. "I was in the middle of a nice dream, too... why did I get such an annoying kid as my master? Ah, but whatever... I'll forgive you this time, since it feels nice to be in my real form again."

The other Ghost Hunters and The Lunatic could only stare on in shock at the immense display of power from Raiju, the legendary Heavenly Beast of Lightning.

[You have your target, Raiju~ he's right in front of you.] Zelestria said within Finn's mind playfully. [Take him out, and you get a treat~]

Raiju's ears twitched a bit upon hearing this in his mind as well since he was connected with Finn, then growled.

"... That ugly bastard? Hah. Leave it to me."

"H-Ho... a little puppy, eh?" The Lunatic laughed, but his voice definitely wasn't as confident as before. "You think you can beat me, now that you have a dog by your side? Under the moonlight, I am invincible! Immortal! No matter how much you damage me, I will be resurrected over and over aga-"

"Yeah," Finn interrupted quietly. "... Under the moonlight, that is."

"Wha-?!"

Suddenly, the grey thunderclouds above shifted, converging together to block off the moonlight completely. They radiated with sparks of electricity and covered the entire sky for as far as the eye could see, so flying through was impossible.

In an instant, the courtyard was sent into darkness, with all sources of light cut off. Raiju's eyes lit up a menacing neon blue, his entire wolf-like body radiating with sparks of lightning, as he growled in anger.

"GRRR... WHO ARE YOU CALLING... A PUPPY...?"

"T-Tch... I'M NOT AFRAID OF YOU!" The Lunatic roared, spreading its arms and turning his palms upwards. "Mystic Art —

The five purple orbs above its head suddenly began shaking violently, and the glowing white silhouette of a crescent moon formed around them. Then, like an eye, it opened.

Instantly, a terrifying and dreadful suction force enveloped the courtyard, stronger and more deadly than anything the group had experienced before. Deep inside the crescent moon that was now shaped like an open eye, a cold and empty purple void lay, drawing people in only to claim them there forever.

"Ngh...!" The Ghost Hunters held on to the few pillars that remained standing, but that wouldn't last for long. Cracks were starting to appear in the stone as the entire cathedral behind them began crumbling away, drifting into the abyss that lay beyond that eye.

But Raiju, completely unaffected, merely growled and took a step forward. Then another. And another.

"GRRR...."

With every step that it took closer towards the Lunatic, more fractures appeared in the ground. The broken cement tiles flew up into the eye of gravity, but Raiju remained unbothered and continued until he was right underneath the Lunatic, who had an expression of shock hiding behind its plastered wide smile.

"H-Heh... what you got, puppy? You gonna lick my feet? HAHAHA!"

Not responding to the Lunatic's question, Raiju slowly opened his mouth and pointed it towards the Lunatic.

It was then that the Emperor knew.

It fucked up.

BOOM!

A surging beam of blue energy shot out of the legendary beast's mouth, tearing through the Lunatic's body and piercing the clouds above.

"GRAGHHHH!" The Lunatic screamed in agony as the electrons of the laser beam spread to every corner of his body, shocking him over and over again to no end.

By the time the laser dimmed and faded away and Raiju closed his mouth, the Lunatic was all but unconscious, and fell to the floor with a gaping hole in its body.

"... After that... it should be dead, right?" Acaya muttered.

"... Heh."

"No, stay back!" Raiju roared, then immediately got into fighting position again as he narrowed his beastly eyes on the Lunatic, who slowly rose back from the dead, the hole in its body closing up.

"... A slight miscalculation, puppy," it snickered. "Look up."

Raiju and the other Ghost Hunters all turned their heads to the sky, and realized what happened. Raiju's laser beam had pierced the clouds as well, unintentionally allowing the moonlight to reach the Lunatic and rendering it immortal again.

"NOW, IT IS TIME TO END YOU ONCE AND FOR ALL!" The Lunatic declared, a wide and psychopathic grin on its deformed face. "Emperor's Divide — Moonfall!"

It raised its arms into the air once more, calling upon the power of the almighty lunar moon, preparing its final attack.

"Shit...!" The Ghost Hunters all covered their faces and prayed to heaven this was not happening, but there was no escape.

The courtyard was enveloped in a bright white light, signaling the power of the moon, and-

... Nothing happened.

Finn and Raiju, at the same time, smirked.

"Wha..." The Lunatic whipped his head around and stared up at the sky, only to see his precious moon, shattered and broken, falling below the horizon. "What... no... NO, THIS CAN'T BE...?! HOW?! MY MOON! MY PRECIOUS MOON!"

"Kid, that wasn't a bad plan," Raiju said with a laugh. "I'll give you credit for that one. You're stronger and smarter than I originally thought."

"... Hmph." Finn snorted, then folded his arms and stood beside his Heavenly Beast. "You thought we were aiming to kill you, Lunatic? No... we knew that as long as that moon was still in the air, you were invincible. So... we needed to get rid of it first."

"I...Impossible..."

"Now..." Finn began, then, together with Raiju:

"... Face your demise, Emperor."
