A mystery

Loki followed the Chloe look-alike and found nothing unusual, it was then he received a call from Harold.

"I looked into it that girl's name is Illya Gardson, she has a proper mom and dad, and is a rank four martial artist. I checked everything but it seems like she really isn't our target." 

"What about her family are they her biological parents?" 

"The father is her biological father, but the mom that's just her stepmom." 

"Got any information about the father and do you think he has some relation to our target?"
