A world of silver and darkness!

Spirit sword, it was probably among the most mysterious power that exists in this world. Why do spirits exist in these mysterious weapons? Where do they originate from? Even the goddesses themselves don't know the answers to these questions.

It was believed that these powerful existences known as "spirits" were born from the souls of special chosen few, while others believe a witch placed a curse on the spirit race trapping them within them. However, so far there has never been an accurate answer for any of these questions.

The spirits themselves doesn't seem to know the answers to these questions themselves either. Each spirit are born with different and unique abilities that sets them apart from others. They each resides within different types of weapons; all are born with the instinctual feeling of supporting their chosen partner.

However, while all spirit weapons each has their own spirit dwelling within them, there is a difference between them. Depending on the rank of the spirit weapons some spirits could easily communicate with their partners through telepathy, while others communicate with them through dreams.

Another difference is that some spirit could materialize into physical form and fight alongside their bonded partner. Though, only those of the highest rank could gain physical form. However, there was another special ability that all spirit weapons possess.

That was 'Spirit possession' An ability that is believed to allow the dwelling spirit to temporarily take control of the bonded partners body, allowing the spirit to access their original powers which is usually sealed when in weapon form.

A powerful surge of energy burst forth from Ethan's, no from Grim's body as he looked up at the humanoid creature.

And with a small gesture of his hand he said, "Well, shall we dance. Why don't we let loose and go wild." Grim revealed a mocking smile as he said that.

ROOOOOOOAAAAAR!

Soon, the black ball of light was then fired like a cannon towards Grim. Wherever the cannon past the atmosphere would shake and rumble fiercely from the force. However, Grim didn't panic instead he pointed his index finger towards the beam of black light coming towards him and a silver light began to gather at the tip of his finger. Soon, the silver light was roughly twenty centimeters in diameter, a cannon of silver light shot outwards from the tip of his finger.

The silver light met the black light from the front as the two attacks collided at a single point in the sky.

BOOOOOOOOOOOOOOOOOM!

A loud explosion resulted from the collision of both attacks, for an instant the sky was illuminated by a blinding light. Creating a beautiful work of art as the sky was illuminated by a silver and darkness two contrasting light covered the forest as the surroundings rumbled fiercely and a great deal of the forest was completely destroyed, and several mountains that extended a few kilometers away collapse from the resulting shockwave! Losing their structures.

Despite the fierce wind pressure, Grim didn't seem to be affective by the intense wind pressure as he narrowed his eyes toward the dust cloud that had risen as a consequence of the earlier attack just now. "Heh, I see... so that wasn't enough to take you down. Huh, good." Grim muttered, 'I just got the opportunity to come out, would be boring if things end like this.' Grim thought. However,

ROOOOOOAR!

A loud cry echoed and shook the forest as the humanoid creature lunged forwards, thrusting its claws. However, seeing its deadly claws coming towards him, Grim only showed an indifferent expression.

And with a small kick he leapt off the ground and accelerated towards the humanoid creature, with his fist arch back!

BANG!

CRACK!

When Grim's fist that was clad with spiritual energy collided with the humanoid creature's claws a fierce shockwave erupted from the impact dispersing the remaining dust clouds, before the sound of cracks sounded out.

The humanoid creature's claws were breaking to pieces and falling apart.

"Oh, that's all it took. Huh, disappointing." Grim sneered, before twisting his body mid-air and landing a roundhouse kick to the neck of the humanoid creature, its neck caved in as its body was pushed back from the force!

"Tch, that exoskeleton is a huge pain in the ass." Grim mumbled as he felt a slight pain in his leg. Soon, six pairs of wings appeared on Grim's back. Two white angelic wings, and two silver wings followed by two golden wings.

A silver light suddenly envelops Grim's figure as a giant sword appeared in his hand. Meanwhile, the humanoid creature's broken claws were already starting to repair themselves. However, now that it found out Grim could damage its body it seems to be rather cautious now.

ROOOOOAAAAR!

It once again roared in fury! As its red glowing eyes shone dangerously.

...

"Hmm... this energy, what is that?!" The lich muttered to himself, despite not having an eye there was a strange gleam dwelling within its skull.

He had sent two of his most powerful undead, the spearman Owen, a master of the spear. And the undead death king! Two extremely powerful undead.

"I need to end this fast; I have already used up too much magical energy. It would be annoying to control that thing if its consciousness awakens." The lich muttered as it sends more magical energy towards death king.

...

Meanwhile, Louisa hovered over the forest as she gazed down below, she felt two powerful presences facing each other and became curious.

"This aura. Ethan no... Grim, did they used that ability? Strange what exactly could he have faced that had managed to force him into using that ability?" Louisa wondered.

She wasn't a stranger to the hidden ability known as 'spirit possession' In fact she had faced many spirit sword users in the past who had used that ability against her. However, Ethan although he hid it well was a naturally prideful man, so far, he had refused to rely on that ability unlike the other spirit sword users and decided to rely on his own abilities.

Even in the worst situations he never resorts to using that ability, Louisa could only recall him using it twice. That was when he had fearlessly challenged the man known as the "Overlord" And was forced to use that ability.

And when he had faced one of the top generals of the goddess of death, roughly one century ago.

"... Well, I guess I'll just leave that to you, then." While saying so Louisa's wings flap softly as she accelerated through the forest.

Meanwhile,

BANG! BANG! BANG! BANG!

The death king thrust its claws forward, attacking Grim's torso. However, Grim easily parried all of its strikes effortlessly. The two moved at blinding speed exchanging blows as their weapons clashed!

"Divine judgmental slash!" Grim roared as he slashes ferociously forward! In response to his attack the death king thrust its claws outwards!

BOOOOOOM!

Both attacks collided. However, the results was?

ROOOOAAAAAR!

The death king lost its arm as the greatsword in Grims's hand slice through it like hot knife cutting through butter. "How pitiful." Grim jeered as he watches the death king writhing in pain of its missing arm.

ROOOOOAR!

The death king roared angerly, at the same time its severed arms instantly grew back as though, time had gone into reverse.

A cheerful smile peaked out from the corners of Grims lips seeing that. "Regeneration huh, well I guess that is to be expected. In that case." Soon, the golden wings behind his back started emitting a faint radiance.

The death king gathered dark energy from its palm and fired it towards Grim, even though this attack wasn't as strong as the first one it still had enough force behind it to be a fatal attack!

Meanwhile, the two pairs of golden wings behind Grims's back were suddenly ejected, becoming two pairs of golden blades, the atmosphere trembled, and spatial cracks appeared in the sky.

It was as if these golden wings could easily slice through space itself!

The golden wings collided with the beam of black energy. The two attacks fought and tried to gain supremacy over the sky! However, soon the golden wings started tilting the balance of fate in its favor! It gradually pushed back the beam of black light and was slowly approaching the death king who hovered in the distance.

The death king senses the danger the golden wings impose and quickly used its two wings to cover itself like a cocoon.

The golden radiance of the two wings slowly covered the sky, as the wings made contact with the death king's body.

BOOOOOOM!

A fierce explosion took place in the sky. However, Grim narrowed his blue eyes and with his "spirit eyes" He could see the soul of the death king still hovering where he was. However, its wings were in tattered, and its exoskeleton had been badly damaged from his attack.

ROOOOAAAR!

The death king growl as it panted. Its red eyes lost a lot of its gleam as it stared warily at Grim who observed it from the distant, it was plainly obvious that he was being looked down on.

This only infuriated the death king even more. "YOU! you are looking down on me! A filthy human!" The death king roared! However, hearing this Grim raised an eyebrow. "Oh, you can talk?" He was genuinely surprised hearing this. "... So, you actually had intelligence the entire time, huh. And here I thought you were just a brainless idiot." Grim mocked.

The death king clenched its fist in fury! In the underworld the death king were respected and feared by everyone! To think someone would actually disrespect it to such extent. 

"Die! You human trash!" The death king bellowed, surrounding its claws in dark energy and thrusting it towards Grim's chest. However, Grim easily deflected its attack using his greatsword! The two showed impressive mobility as they flew around exchanging blows.

Fierce shockwave erupted whenever their attacks met in the sky!

However, Grim frowned as he could feel his energy being suppressed by the strange dark energy from the death king, 'That aura... is it somehow eating away my energy?' He wondered to himself. Meanwhile, the death king glared at Grim with visible hatred in its glowing red eyes. 

[Grim, will you end this already! We don't have much time in this form!] Ethan's voice sounded from within Grim's mined.

'Hmph, your so loud... well I was already planning to end thing off with the next attack anyway.' Grim responded. As he surrounded himself in a silver radiance, meanwhile the death king covered its body in a black energy.

Grim took a stance with his greatsword and accelerated towards the death king, while the death king also moved closing the distance with its claws clad in a darkish energy arch back.

Once all the distant between them were completely closed off, Grim swung his greatsword in a horizontal arc, while the death king thrust its claws forward.

BOOOOOOOOOOM!

A fierce shockwave erupted from their collision, the forest down below was blown away scattered debris and a thick cloud of dust was raised. From a distance anyone would be able to see two beams clashing against each other creating two completely contrasting colors, a world of silver and a world of darkness!
