Looks like my real wife has returned

Valentina looked into the eyes of the man before her. "Why do I feel like I'm being constrained?" She thought, as she sensed a massive connection coming from the man before her, who didn't even consider her an opponent; he was simply... taking the fight calmly, and that irritated her.

She was Rias, the woman who could slaughter armies, but why was a man treating her like a child? "Who the hell is this Valentina he keeps talking about!" She roared internally. It was as if... her thoughts were fractured, and her concentration barely existed. She knew she was stronger than him; that was obvious, but...

"Why does he know everything I'm going to do?" She questioned herself. She had already grasped that this man knew her, but... Why did he know her so well? Who was he?!
