Underground Idols

The Akihabara district in Tokyo is known worldwide as a mecca for "otaku" or geeks. It's also where a number of girl groups dance and sing. The otherwise obscure "live theaters" where they perform have become major new attractions for the groups' wildly enthusiastic fans. But for these underground idols, the showbiz life is rough. They don't earn much. Rival groups are forever a threat to displace them. How old can the girls get before they lose their appeal? Yet they do not easily abandon their dreams.
