Under the burning holy light, darkness erupted, shrouding the nearby clouds in an inky blackness. Vesuvius flapped his colossal wings, each beat sending out gravitational shockwaves that tore through the heavens, knocking down countless lesser angels like leaves in a storm.
With a roar, Vesuvius ignited, his purplish solar flames intertwining with the demonic dragon's bright red fire. The sky itself seemed to burn, consuming the heavens in a fiery inferno.
The white buildings melted, the white clouds dissipated, and the white light diminished under the purple and crimson hue.
'Two dragon kings fighting in a single battle—that has never happened before.' Vesuvius couldn't help but want to fight with all his might, unwilling to show less power than the demonic dragon.
Suddenly, an enormous beam of light shot out from nowhere, colliding with the demonic dragon in a cataclysmic explosion of light and crimson fire. Smoke rose and steam hissed, with countless glowing sparks flying everywhere.
"Who dares! Grahh!" An enraged roar cut through the chaos, followed by a clarion trumpet and an ethereal voice, "It's me, Gabriel! Today I will extinguish your eternal wrath, corrupted dragon."
"You insignificant insect! I will tear your wings off one by one!" The seven-headed dragon emerged from the flames, its fury propelling it forward.
Vesuvius's attention was directed to a rapidly approaching holy aura caught by his senses. Only a thousandth of a second later, an enormous burning spear pierced through the sky toward him, cloaked in silver flames.
A barrier of burning darkness and warped space formed in front of him, its divine energy giving it a golden glow.
The spear and the barrier clashed, detonating in a shower of silver and golden sparks.
'Like before.'
Under the strain, Vesuvius's horns lit up, and the barrier strengthened as a crown materialized above his head. And, at last, he exhaled his gathered breath, unleashing an enormous beam of darkness that seemed to suck in all light as it swept away the angel of bravery.
He turned his neck, sweeping the beam through the angels swarming him, sucking them into its destructive path like a giant blade forged from a black hole.
Yet more angels arrived, their countless domains overlapping, their collective light growing brighter and brighter, pushing against Vesuvius's darkness. He closed his mouth, already charging another breath, the hot sensation thrilling him.
'This is the power I always wanted! To face against armies of heaven straight in heaven!'
The eighteen-winged angel burst from the darkness again, his sword blazing even brighter as he struck the barrier with a thunderous clap—the strike stronger then ever before.
The barrier trembled as the blade of light and fire clashed with the wall of darkness and flame.
'He truly grows stronger!'
Vesuvius felt his divine energy draining like a river to support the barrier. He drew more energy, tapping into his stars. The barrier and his domain expanded like an enormous bubble, devouring the angels in its path, using them as fuel to grow stronger, and pushing back the eighteen-winged angel.
Mikhail's body cracked under the force, and his armor shattered.
Yet Vesuvius remained vigilant as a second magical array of stars flickered to life. Simultaneously, silver flames and light gathered into an enormous, towering form of a monstrous angel, burning with flames around its countless eyes and whip-like tongues of light moving alongside its eighteen enormous wings.
'So this is your true form.' A beam erupted from the dragon's mouth, all the stars linking together to empower it with a massive magic formation. Simultaneously, the monstrous angel brought down its blade against the incoming beam, light, and darkness colliding with earth-shaking force.
