Ikemen wa Juuchuuhakku Gesu Yarou (E05)

Jess and I met a young Yethma named Ceres in a town we stopped by amidst our travels. Upon Jess's request, she guided us to the site of a monastery that burned down five years ago. As we were setting down some flowers at the site, a young man wielding double blades suddenly appears before us accompanied by a dog. He's cool, strong and handsome... I don't like him, he's like my natural enemy... Who on earth is this guy? (Crunchyroll)
