Code: Realize - Guardian of Rebirth/Arsène Lupin

''A notorious and nefarious master thief who is perpetually cheerful, optimistic, and overflowing with confidence — traits more than justified given his overwhelming success. After encountering Cardia, he whisks her away to London for reasons known only to himself.''
