The English version is designed as a web-based manga and anime style virtual world. What you can do is create a mini anime/manga like dynamic flash avatar called SELFY and dress it up the way you want. You will also have your own personal room to decorate and invite people to. There's a cosy town called SELFY Town where you can go to meet people or go fishing or play games. For now, the only two games are fishing and old maid. I haven't tried the old maid but the fishing was hard like hell! >.<" And of course they have forums where you can hold discussions or create groups.
Well, for now there's nothing much. I guess it's still too new. But you can invite your friends and you and your friend will get loads of coins when your friend accepts your invitation. There's also a diary system which I'm not sure how it works yet. You will also be rewarded with some coins for daily log in. For now and I'm not sure for how long, everything in the store is going for really cheap. So it's a good time to start playing. >:D If you want, just give me your emails, I'll send you an invitation. :)
