Against Rex II

Luna didn't waste any time. With lightning-fast reflexes, she lunged at Rex, her daggers flashing as they struck out toward him. Rex barely managed to block the assault, the clash of their weapons ringing out. His smirk quickly faded, replaced by a grim realization as he realized she was stronger than he had anticipated.

Leon, meanwhile, moved with precision and efficiency, taking down Rex's lackeys one by one. His strikes were swift, and each movement was calculated. With his newfound Tier II strength, he dispatched the mobs effortlessly, clearing a path through the chaos. For the first time, he felt the true extent of his power, the magic sources he'd absorbed fueling him with renewed vigor.

He even didn't used his Summons even, just dispatching them with his magic and swordsmanship.
