In an unknown dimension with red skies and desolate surroundings filled with sinister chakra and nature energy,
"Found him!"
The astral demon clan prince opens his eyes.
"I can sense the location of my curse that I placed on him. He has isolated himself within a pocket dimension within this world. Currently, he must be agonizing in pain as my curse slowly eats his soul."
"Then what are we waiting for? It's time to pull that stinky rat out of its hole." The cloaked figure grows impatient.
"These are the spatial coordinates." The princes transfer the spatial coordinates to the black-cloaked figure.
"Dimensional Sever,"
The cloaked figure slashes open a cross-shaped space channel and walks into it. The demon prince follows him.
The duo reappears within the depths of the planet they are standing upon. Hot magma flows from various crevices in the surrounding rock bodies. The smell of sulfur and molten lava wafts in the air. A Burst of high-temperature air and toxic fumes greets them.
Both erect an energy barrier to ward off the heat and toxic fumes. They notice a castle on a giant rock bed floating in a sea of lava.
Hmm…
The cloaked figure scrutinizes the castle with narrow eyes.
"An artifact?! No wonder he could evade our detection for so long. This seems to be a semi-divine-grade relic. Also…"
Both of them look around and notice multiple enemies in their surroundings. Various Abyss monsters fly out of the castle and various foreign lava abominations erupt from the lava sea.
The astral demon prince ignores the monsters and attacks the castle with a powerful energy projectile.
BOOM…
Their surroundings tremble from the powerful energy undulations. A transparent barrier shrouds the castle and repels the attack.
"Tch! That stinky rat just got a turtle shell." The prince grumbles in annoyance.
He inserts his hand into the surrounding space and pulls out a curved blade. The prince infuses his energy into the curved blade. A giant apparition of a horned figure with wings appears behind the prince. The apparition grabs the curved blade and swings it toward the barrier to release a cyan ring of energy.
BOOM…
The cyan rings explode on top of the barrier and unleash a powerful burst of energy that decimates the surroundings. It cleaves the surrounding rock structures and blows away the surrounding lava. Slight ripples spread across the barrier, but there is no visible damage to its integrity.
"It's sturdier than I thought." The prince clicks his tongue.
Swish…
The cloaked figure swings his blade and eradicates the last lava abomination attacking them at the moment.
"Why don't you give it a shot?" The prince turns towards him.
"I don't have an artifact!" The cloaked figures disperse the energy blade in his hand.
"Here!"
The prince tosses the battered spear of Ama-no-hoko toward the cloaked figure.
Hmm…
The cloaked figure catches the spear and scrutinizes it.
"It's in quite a rough shape and has lost most of its energy and spirituality."
The cloaked figure inserts his chakra in the spear and activates various Fuinjutsu seals carved on the spear. Bright white and dark black inscriptions appear on the spear. A giant Taichi apparition appears behind the cloaked figure. He raises the spear and points its tip toward the barrier.
BOOM…
A deafening blast of energy escapes from the tip of the spear. The energy blast hits the barrier and generates multiple small cracks on its surface.
"It's working!" The prince cries in excitement.
However, the barrier quickly repairs the crack and recovers to its former state. The cloaked figure grasps the spear and stretches his hand backward in a throwing posture. Crimson energy envelops the spear.
Swish…
He swings the spear and throws it toward the barrier.
BOOM… BOOM…
The spear releases a thunderous cry and tears through the surrounding space as it rapidly approaches the barrier.
BANG…
A muffled sound escapes in the surrounding as the spear clashes with the protective energy field. The tip of the spear penetrates the energy field. Multiple cracks spread across the barrier due to the impact of the spear.
RUMBLE… RUMBLE…
Multiple shockwaves escape from the clash and utterly decimates the surroundings. The underground cavern collapses as a result of the remnant energy. Rock and debris fall on top of the duo but get blocked by their barrier.
A powerful pillar of crimson energy burst through the ground and decimates a wide area of several hundred kilometers in their surroundings. Numerous cracks spread across the surface of the entire planet.
"Woah!"
The prince exclaims in shock.
"Your attacks are as flashy as usual."
The cloaked figure recalls the spear and glares at the barrier. The cracks in the barrier are regenerating at a much faster rate than before.
"This will take a while!" He clicks his tongue in annoyance.
He grips the spear and prepares to throw it again.
RUMBLE… RUMBLE…
Suddenly, the entire planet trembles violently. A massive amount of chakra gathers around the atmosphere of the planet.
"What's going on?"
Both of them fly into the sky and glances at their surroundings. The crimson pillar of energy has blown away a giant hole through the gloomy sky of the planet. A starry sky is visible through the giant hole.
Multiple cracks appear in the sky and a giant Fuinjutsu seal becomes visible to the eye. The Fuinjutsu seal covers the entire planet. The Fuinjutsu seal glows with a purple hue.
"This fuinjutsu inscription…" The expression of the prince turns ugly as he recalls the sealing pattern.
"It's a trap!" He clenches his fist.
"Well done figuring that out, prince!"
Two humanoid figures with twisted black horns walk out of the castle. They have shoulder-length pale gray hairs which part down the middle in a zig-zag pattern. Their ram-like horns are adorned with ring-like ornaments. They have delicate facial features and are dressed in a black kariginu hunting robe, baggy pants, a pair of tengu-geta, and white gloves.
One of the figures has a pale face and a black aura emanates from his body. Both of them smirk at the astral demon prince and the cloaked figure.
"You both…" The astral demon prince glares at them with a bone-piercing gaze.
"JASHIN… KISHIN! The traitors of the astral demon clan." He grits his teeth in fury.
"I won't forgive you for your sins." The prince almost loses his mind.
"Calm down!" The cloaked figure pats his shoulder.
"Everything is going as I planned!" He mumbles and stares at the skies above the desolate planet.
"Will you come out on your own or will I have to drag you out?" He continues.
"WHAT!" The prince is startled by the cloaked figure's sudden remark and raises his head.
Whoosh…
The dark clouds above their head disperse to reveal multiple massive armies of Abyss monsters. There are countless abyss nightmares, head hunters, soul-eaters, dreads, and centurions. Five figures are leading this army of abyss monsters, a giant black twin-headed dragon, a giant creature with the upper body of a human and the lower body of a snake, a gigantic colossus with a height much bigger than the entire planet, a giant flying insect of an unknown species, and a pale humanoid figure with flat, curved bull-like horns with two golden Byakugan and a Rinnesharingan present in the center of his head.
"An Otsutsuki with pure royal bloodline!" The cloaked figure frowns at the sight of the Otsutsuki.
"I didn't expect the royal family of Otsutsuki to harbor a traitor among their bloodline." The cloaked figure calmly mocks them.
'These abyssal lords aren't much of a problem. I can easily deal with all four of them and their army. The real trouble is that Otsutsuki with the Royal bloodline. Otsutsukis with pure bloodline are much closer to their primogenitor and thus can draw more power from their bloodline. They can also sacrifice a portion of their bloodline to temporarily summon a clone of their ancestor. I am no match for those powerful prominent figures.' The cloaked weighs his options.
"Don't lump me with the likes of these foul creatures. I am here to exact vengeance on behalf of my fiancé, which you murdered in cold blood. I have been looking for you for centuries and finally, I found you after all that trouble. These filthy beings happen to have the same objective as me." The Otsutsuki proudly crosses his arm.
"You have nowhere to escape. This giant Fuinjutsu seal covers this entire planet has sealed this entire dimension from both inside and outside. Nobody from this place can leave this dimension and similarly nobody from outside can enter this dimension." The Otsutsuki declares with a mocking smirk.
"Now, prepare yourself for my judgment!" He declares.
