Kagome is a Wayne, she knows her dad is Batman but Bruce doesn't know she knows. Only a few people actually know that she knows anything about the caped community other than that heroes are cool. A betting pool is actually going around on who finds out when/how. She's somehow managed to keep the fact that she's traveling to the feudal era and regularly risking her life a secret from her dad and most of her family. So, when a small group of Justice League members somehow show up in the feudal era practically right in front of her she knows the jig is up. Her first thought is... Well... shit.
