After killing Ellen, Theo dropped to the ground and spat a mouthful of blood before he realized Ellen still managed to react to his attack and hit his chest with her elbow. If she were a fighter like him instead of a magician, he would have died too.
"Seriously… Even with all my current power, I can't beat her completely. No, I feel like Ellen is stronger than the assassin leader the Lange Family sent." Theo narrowed her eyes and sighed. "So, this is what it means to have enough experience and skill."
He shook his head helplessly before finding Ellen returning to the field.
"You should recover first," said Ellen as soon as she met Theo.
Theo nodded, closed his eyes, and returned to the real world. A few seconds later, Theo's figure reappeared as he said. "I'm good now."
