Black markings began to encroach over Tetsuno's body, covering him in ink-like patterns. The ominous green eyes of Beelzebub watched as the curse mark spread over Tetsuno.
"Do you believe you can defeat my toy without your power?" Beelzebub hissed. "Soon, the curse will completely seal your aura.. and I will then consume you."
A raspy hiss let out from Tetsuno as he breathed in. His posture became loose, all form of tension gone, as his head hung to the side. His body began to glow red and smoke began to rise up from him, his chains becoming a hot yellow-white as they were superheated. The ground about him at his feet began to turn into molten rock and the cloth wrapped about his body caught fire, flaring up like a cloak of flames. The markings across his body then faded out.
The curse mark had no affect on him because he could simply scorch it off.
Beelzebub's head tilted slightly. "Oh?"
Tetsuno then leaned forward, putting his hand against the ground, melting it as his fingers sank into the stone. Steam began to rise from the stone as it began to glow in front of him.
Then he lifted the mask halfway, exposing his black scorched jaw. Then he let out a raspy breath, smoke drifting from his jaws like that of dragon's breath.
Then the ground around him erupted in waves of heat and volcanic rock as he wrenched a massive chunk of earth from the ground, the force of it sending a split through the entire chasm, red lava erupting from the crack like a massive fissure. In Tetsuno's hand he held a massive sword of molten rock, the weapon larger than his own body, flames engulfing the blade. The air then began to cool it, the rock solidifying as Tetsuno absorbed the heat from it and it became black, sleek and crystalline, like a blade of pure obsidian. A wave of red ran through the weapon, strange demonic markings flashing across its surface.
Tetsuno drew the giant weapon over his shoulder and bent in his knees, flames coiling about his body as the ground began to shake and he began to sink into the molten earth that melted below him.
A shudder ran through Beelzebub's body as he watched the young demon take stance.
Tetsuno's jaw lowered then, exposing the firelight within his mouth, smoke rolling out from his teeth. And then the raspy whisper of a mumbled word, though mispronounced and hard to understand, though clear in what the word was;
"Die.."
Suddenly the entire chasm began to fall apart as it was super heated, the walls breaking apart as cracks of red light formed across the walls and streams of lava flowed from above while the earth became magma.
Tetsuno the heaved the blade forward, sweeping it in a downward thrust that sent waves of magma flying across the chasm, enveloping Beelzebub's massive aura puppet. Tetsuno then leapt into the air, the magma rippling from the force of his jump, as he soared towards the puppet, spinning the blade in a wide arc as it completely severed the puppet's torso from the lower body, releasing Zealous as the green aura faded out.
Zealous landed on a section of super heated rock, black aura now covering his body. "Thanks, but I had it under control." Zealous spoke, but then he realized Tetsuno wasn't even paying attention, instead he was barreling towards Beelzebub. "He's lost it." Zealous shrugged, then observed his surroundings. He was astonished by the destruction Tetsuno was able to bring.
The massive blade in Tetsuno's hands suddenly began to glow, the markings spreading over its form as it began to change, melting down and reforming into a new shape; it now took the form of a massive six foot long katana. Beelzebub stepped back, holding up the God Slayer as Tetsuno drew near, landing on a pool of magma, then shifting his foot forward, crashing it to the ground and sending ripples through the lava as he swiftly swung the katana, bringing it down on Beelzebub, who blocked, the God Slayer's staff meeting the obsidian edge of Tetsuno's blade, and as the two weapons made contact, a soft *click* emitted from the katana. Green chains suddenly sprung from the lava while the spikes upon Beelzebub's back grew and shifted, becoming black and green serpents the snapped and hissed, coiling towards Tetsuno. They seemed to crush him, enveloping his body momentarily, but in the next instant a wave of heat flashed through the chasm as the chains and snakes burst in an explosion of magma and fire.
Beelzebub tried backing away, but Tetsuno closed in on him too fast, the katana swinging from the side. Beelzebub successfully blocked the first strike, but an instant later the katana changed form, transforming into a perfectly identical scythe to the God Slayer. Beelzebub began to disengage, trying to leap back, but Tetsuno lifted his mask and ephemeral chains shot out, enveloping themselves about Beelzebub's arms and legs as Tetsuno dashed forward and, in one swift motion, spun the scythe about his body in a wide arc before the blade then plunged into Beelzebub's throat, decapitating the demon as a shockwave exploded through the chasm.
As the aura chains faded out in shattered flakes of emerald, Beelzebub's head began to reform atop his head, and as it did a guttural scream of rage like that of a banshee emitted from the Demon Lord's throat.
"NOOOOOOOOO!!!!" Beelzebub screeched, "HOW CAN THIS BE!! I CANNOT BE DEFEATED BY WORTHLESS INSECTS!!!" Beelzebub stepped forward, swinging the God Slayer, but as the curse mark spread over his body, his movements became slower and weaker.
The blade of the scythe deftly sank into Tetsuno's shoulder, barely breaking his skin.
Beelzebub froze.
"No.. no.. NOOO!!"
Tetsuno's head tilted to one side, smoke coiling from his mouth as his hand slowly lifted up to his mask.
"YOU CANNOT DO THIS TO ME, YOU SCUM!! I AM BEELZEBUB, THE GREAT DEMON LORD OF-"
The hiss of searing flames drowned out Beelzebub's screams of rage as Tetsuno lifted his mask and let out a stream of searing fire from his jaws and eyes, melting Beelzebub's body to nothing more than ash. Before the demon lord could reform himself, Tetsuno hunched over and grabbed the demon's Soul Chains and raised them above his black jaws, flames dancing about his skull head.
He then lowered the chains into his mouth.
*CRUNCH*
