"So Rias is your spy?"

"Not a spy. She just monitors stuff, like a...uhh...informant. That was the deal between her and Zero" 

"So, this Zero guy. He is dead now. He told me that he was killed. Why don't you find them?"

"It's been 30 years since he died. Most of them are probably dead by now. And we did try to find them, but it was a failure"

"Uhh...how old is your daughter?"

"Why do you want to know that?"

"Just curious"

"She is 22"

"...."

Zero died 30 years ago, and she is alive. Zero is her husband, and she has a daughter who is 22 years old. How does she have a daughter if her husband died 30 years ago?

"She has a boyfriend by the way"

I didn't ask that!

"How did you have a daughter? You did something--"

"It's better if you don't know about it. And she is mine and Zero's daughter. A normal human" 

"So, are we done now?"

"Why don't you take your mask off? Isn't it hot inside?"
