About Uriel's and Raphael's Aces, here is some trivia about them.

Raphael's Ace, Deethelm; the name is an alternate spelling Ishibumi made as the name is actually spelt Diethelm. Along with his last name, Waldseemuller, he is German as they are both German names. The last name comes from the German cartagropher with the same surname, Martin Waldseemuller.

Uriel's Ace, Noro Raimondi; his surname comes from the Italian engraver with the same surname, Marcantonio Raimondi. Since his first name is Japanese and his last name is Italian, that would make him Japanese-Italian.

There is referring connection between Deethelm and Noro and who they are named after. We know that Deethelm is Raphael's Ace and that he and Noro are comrades well, Marcantonio worked with the famous painter Raphael and because Deethelm and Noro have a connection like them, this is a reference to the connection of how the person Noro is named after is related to the painter of the same name of the Angel Deethelm serves.
