That gladiator lady is back! This alternative slip cover for PSP game Kentoushi: Gladiator Begins was a freebie at an event in Tokyo's Akihabara. The standard cover has a shirtless gladiator dude.
The back of the cover reminds people on Japanese internet of one thing: a porno. This is not pornography, it is a video game!
