It's a mystery, but not! The released art for PSP game Misshitsu Sacrifice from Japanese publisher D3 appears to have forgotten things - namely, underpants.
This promotional image features more of 15-year-old Miki than perhaps she'd like to be shown. And as the Japanese internet has pointed out, this game makes it appear as if all the young heroines cannot be bothered with dressing themselves properly. Underwear is important!
Except in the bath.
Misshitsu Sacrifice is a psychological adventure thriller out next February in Japan. It is rated ages 15 and up. There's blood, too.
