My Cute Little Sister Has a Promotional Video
The ultimate little sister game, says
Here's the latest promotional video for My Sister Can't Possibly Be This Cute Portable -- yes, an actual PSP game featuring little sisters who are admittedly adorable.
My Impossibly Cute Little Sister Portable hits on the 27th opposite Valkyria Chronicles 3. Namco Bandai says it's "the ultimate little sister game."
Be sure and pre-order to get the "How to Imoutalk" DVD, which teaches you how to talk like your little sister ("Imouto" in Japanese, explaining the cross lingual pun in the name).
