New Wings

In the second season Sora returns to the stage after attempting the Legendary Great Maneuver with Layla. This leaves Layla's shoulder injured and unable to perform. The absence of her co-star, having retired to further a career in Broadway productions, prompts a slight decline of the Kaleido Stage. Because of this Kalos brings in a new recruit, Leon Oswald (a lofty trapeze artist). It seems at first that Leon is reminded very much of someone due to Sora's presence, and at times this causes him to either be really rude or really sweet to Sora.

Despite this, however, Leon disapproves Sora as worthy of being on the stage with him. This leads to the most talented of the new Kaleido Stage recruits (the Chinese May Wong, who is also an ex-figure skater) to question and challenge Sora's position as Leon's partner and star of the show.

Sora's first goal in the season is to attend the circus festival in Paris, but the competitors will do anything to attain the title of 'festival winner': betray, deceive, or even attack their opposers. The atmosphere and attitude this creates does not bode kindly to Sora's carefree, optimistic, ultra-idealistic outlook. It in turn causes her to withdraw from the competition in the middle of her act (or the Angel Act) with the redeemed Yuri Killian, leaving her friends, family and Layla confused and otherwise disappointed with Sora.

Most of the season concentrates on Sora finding, questioning, and pursuing new dreams. After many trials and rejections, Sora eventually aims to become a "True Kaleido Star" while creating a fun, conflict-free stage, the complete opposite of what she experiences at the festival in Paris.
