Aria dragons are a brightly-colored and sprightly breed, perhaps most adored for their lyric calls. Their song-like melodies fill the areas they inhabit; their coos resemble those of birds, only more elegant and refined. They have fairly strong magical capabilities, but tend to reserve these strengths for last-minute defense, choosing to live their lives in simple peace. Arias, sticking to the tropics, typically live quite far from human settlements, giving rise to the previously held belief that they had gone extinct.
Re-Run long ago decided that his father's life was the best possible life a dragon could hope for. So as the logical consequence he decided to do everything the same way the old Manchmal did and does. Despite the fact that he actually doesn't like Brussels sprouts, he declares them his favourite vegetable and eats them as often as possible. He never even felt the need to decide what his favourite colour is since Manchmal's clearly is a light blue. He is currently contemplating whether it would be more appropriate for him to search for his own Frill mate or to actually court his mother.
Whatever his decision will ultimately come to, he takes joy in an impersonation well done and taken to an art form.
