Well, Cynthia does think he is pretty cool based on action anime serials!

Anyway, Kayneth doesn't have super strong feelings about Atsuro but Nasu mages are emotionally constipated so hopefully he wouldn't take it too personally. He's noticed a lot of people he seems to speak with are fairly intelligent but have a bunch of really weird quirks, and Atsuro... is kind of like that. Seriously, kid, don't tempt fate on the evil spirits front...!
