Arc de la Lune ( 月のアーク Tsuki no āku) is a Blackwing Illusion-based appeal.
|Arc de la Lune|
|Romanized||Tsuki no āku|
During this appeal, the user jumps straight up while performing a pirouette. Upon reaching the maximum height they can reach, they raise one arm gracefully as they bend backwards, and the image of a crescent moon matches their form (aside from the arm). The moon then dissolves into black feathers as the user falls.
