Ars didn't look at enemy's gender, he's desperate to defend, to survive that's all. The enemies killed Caslo's soldiers too before so it's fair (based on standards in their world).

I have read the web novel up ahead (I haven't finished since it has 1000+ chapters & got bored midway) but I forgot this tiny detail.. sorry we'll just have to wait for the manga version (with images as well..) (￣∇￣")
it's all good fam XD
