Hello Kitty to Issho Block Crash V [PCSG00059] (v01.00) (Vitamin 1.x) (JPN) VITA
It's an arkanoid clone, I'm not sure if hello kitty herself is even in the game.
From play-asia:
Test your reflexes, deflect the ball so that it breaks through the ceiling of blocks. Block Crashers are familiar games, however, have you played it with the Kittylers? These attractive girls are drawn by famous illustrators, and they have one thing in common: their love for Hello Kitty, and now, for block crashers.
