Seventeen-year-old Momo shrugs and says she was aware of the dangers when she decided to join other girls in Tokyo's Akihabara district handing out racy fliers to male passers-by and flashing them coquettish smiles.

The schoolgirl knew men would occasionally try to talk her into sexual activities. She even knew that she might be assaulted.

Nonetheless, she willingly put herself in harm's way. With a wry smile, Momo said if a rapist had attacked her, she wouldn't have minded.
