Nine Hells 3
Draco cracked his knuckles as he faced Baal head-on. The final Demon Lord gazed at Draco with two parts hate and eight parts fear. He had just watched everyone in his class of power get turned into either smoking debris, or incapacitated to watch the horror.
He roared to increase his own courage, wielding a greatsword in his right and a greataxe in his left. His aura grew as a red light surrounded him, causing his power to drastically increase as blood filled his eyes.

Since they were in the game, Baal technically did have system-recognized skills. He spun around in a circle and tossed his greataxe towards Draco like a whirlwind, rushing behind it with his greatsword dragging low to the ground.
Draco grinned and simply pulled his arm back, a red light gathering on his fist. The red light stacked upon itself, growing stronger and stronger until it was like a burning flame.
