Wasn't his hair blond because he is part of a noble family? That's how I remember it being described in the novel. Royalty/Nobel blood often have red eyes and blond hair.
I must've skipped that part the lore..
I thought kiolle and Nathan both has blue hair but in different shades of blue. idk. And I thought Kiolle would had a more childish appearance. Surprised to see him to be a BLONDE VERY grown man. that only makes him more bbg imo.
