BlayzBloo: Super Melee Brawlers Battle Royale, as the lunatics at Arc System Works in America called it, is more dead DsiWare. Also known as BlayzBloo: Battle x Battle, the game is pretty much a miniature version of Super Smash Bros.
Only five characters from BlazBlue, the main game's name, made the cut: Ragna, Rachel, Taokaka, Jin and Noel.
