Laliho-chan (more so her...XD) and I created a community where you can download all the Tsubasa Radio shows released. You can also chat on there about the radio shows and anything of the like.
I am currently uploading the first season so that will be up soon. Meanwhile, the second season is up for grabs. ^^
P.S: We are also working on building a website completely dedicated to the radio show so stay tuned for that!
