Riku's Battle Against the Black Hawk

"However, neither the Devils nor high-level demon species were to be taken lightly. This black hawk seemed to be no ordinary demon; it exhibited a level of cunning and wisdom uncommon among its kind.

Riku's thoughts raced as he quickly analyzed the situation. Most ordinary demons relied solely on their hunting instincts, but the creature before him had demonstrated a capacity for strategic sneak attacks, suggesting a higher level of intelligence.

"Screech----!"

Suddenly, the massive black eagle let out a deafening roar that reverberated like a thunderclap. With lightning speed, it launched itself at Riku, resembling a bolt of black lightning. Even Riku, who had transcended his physical limits, had barely enough time to react. Had he been a fraction slower, the outcome might have been fatal.

"Dong--!"

Just before the Black Hawk could strike him, Riku defied gravity, sidestepping the creature and delivering a powerful punch to its abdomen. The impact sent the Black Hawk hurtling hundreds of meters through the air, tumbling in disarray.

However, the Black Hawk quickly regained its composure, its angry roar echoing through the surroundings as it charged at Riku again, its sharp beak crackling with energy.

"Surprisingly resilient," Riku muttered, his eyes narrowing. The Black Hawk's endurance was proving to be a formidable challenge.

But Riku was not one to be distracted in battle. As the Black Hawk came at him once more, a highly condensed energy beam shot from its beak. The dark energy beam streaked through the sky, moving faster than lightning itself.

Riku's instincts screamed of imminent danger. At the last possible moment, he halted mid-air, shifting sideways to evade the deadly black energy column.

"Boom----!"

In an instant, the black energy column struck the ground, causing a cataclysmic explosion that sent shockwaves rippling for miles, shaking the very Earth's crust.

As the dust settled and the energy dissipated, a vast, gaping crater remained in the wake of the blast. Riku, suspended in mid-air, couldn't help but feel a chill. That level of destruction was akin to a nuclear explosion. Had he not evaded in time…

The Black Hawk's eyes gleamed with malevolent intent as it readied another devastating attack.

"Enough of being the prey," Riku muttered, his frustration mounting. He'd had his fill of being hunted.

"First gate, open! Second gate, open! The Third gate, the Gate of Life, open!" Riku bellowed in anger.

Instantly, a visible surge of energy enveloped his form, elevating his aura to another level.

"Thorn----!"

The Black Hawk unleashed another energy cannon, but this time Riku dodged it cleanly. Swiftly using Shambhala, he maneuvered close to the Black Hawk.

"Dong--!"

"Boom--!"

With a nonchalant expression, Riku struck the Black Hawk's lower abdomen with a powerful fist. A muffled sound reverberated as Riku's fist punctured the Black Hawk's defenses, leaving an enormous imprint and causing the creature's blood to spray into the sky.

The Black Hawk, wracked with agony, soared into the sky with tremendous force, akin to an intercontinental missile launch.

"The Fourth gate, Gate of Pain, open!" Riku roared once more. His body, now shrouded in deep green energy, surged with an even greater level of power.

While the first three gates were relatively safe, the Fourth Gate posed a substantial risk. Carelessness could lead to muscular and skeletal injuries, but the strength boost it provided was substantial—especially considering Riku had already surpassed the limits of his physical body.

"Boom----!"

With a footstep that seemed to crush the very air beneath him, Riku ascended into the sky, closing the distance to the Black Hawk in an instant. He looked down at the creature, his anger boiling over.

Riku's fist sliced through the air, creating a powerful shockwave that sent the surrounding atmosphere into disarray.

The Black Hawk, undeterred, thrashed its claws violently, attempting to engage Riku up close.

"Kni--!"

A sharp 'click' resonated in the air as Riku effortlessly twisted the Black Hawk's razor-sharp claws. The creature had never experienced such excruciating pain.

Yet, Riku remained undeterred. He ascended above the Black Hawk, then struck its head with a fierce punch.

In an instant, the Black Hawk's eyes bulged, and its entire head caved in. Blood rained from the sky as it plummeted into the massive pit formed by the earlier energy beam attack.

"Boom----!"

With a thunderous crash, the already enormous pit quaked anew, its surface cracking like a spider's web."
