Those are Japanese. Japanese uses both Chinese characters and their own characters. The first letter (空, Sora) is Chinese, which means being empty or the sky. The second one (の, no) is Japanese, which is similar as 'of'(Not exactly same, but I cannot explain well because that kinda system does not exist in English). It is very unique system that exists in Korean, Japanese, Chinese language and so. The last two letters (世界, Sekai) mean 'world', exactly. Hence Skyworld. You can read it as 'Sorano Sekai'.
I know that because I'm from South Korea, and can speak Japanese a little bit.

The Japanese characters mean Skyworld :3
That's really good. Just wondering though, what are the Chinese letters for, and what do they mean?
Do Chinese and Japanese characters resemble eachother?
What are the chineese/japaneese Symbols? Is that the title of the track or your name? Or both?
