Jonathan

A baby seal that Sora picked up one day. He is capable of doing many tricks and starts performing at Kaleido Stage. During the second season, Jonathan becomes close to Marion and refuses to perform with anyone else. She is his primary caretaker, and even seems to be able to understand what he is saying. Jonathan's real birthday is unknown, but June 29th is the day that Sora took him in, so it is considered his birthday.
