Leon Oswald (レオンオスワルド)

Leon is a French acrobat with a hard and cold character. He is recruited by Kalos to Kaleido Stage but his disgust of Sora Naegino almost makes him terminate his own contract very early on. However, after seeing Sora and May Wong fight on stage, he decides to remain in hopes that one of them can become his true partner. According to Layla, he's so hard on his training and treatment of all partners that almost all of them end up injured and have to give up, earning him an horrible reputation among artists as well as the nickname "God of Death".


The introduction of his little sister Sophie reveals Leon's stormy past. After their parents died, Leon and Sophie abandoned their abusive relatives and sought a trapeze coach named Alain, who took the siblings under his wing and discovered their potential, as well as how they invented put of scrap the Angelic Act. He subjected both of them to an amazingly hard training (especially Sophie, who was the one with the strongest will to perform the act), but at mid-way Leon felt that Alain couldn't teach them anything and left with Sophie.



In the final chapter, Leon is paired up with Sora in the work "The Swan Lake", and after helping Sora perform the act with her, not only fulfills Sophie's wish, but also opens his heart to the idea of performing on a fun, conflict-free stage just like the one his sister dreamed of.

In the OVA The Amazing Princess Without a Smile, he tries to take up more comical roles on the Stage, playing one of the three Fools.
