Japanese name roughly corresponds to "Sky Board"; this is a version of the game "Ghosts!". Each player controls 4 angels and 4 devils on 6x6 board, their identities hidden from the opponent. A player can win by: moving an angel into a goal square from the corners of the opponent's side; capturing all 4 of the opponent's angels; or tricking the opponent into capturing all 4 of the player's devils. Players deploy their pieces and then take turns moving one to an adjacent square. They may capture enemy pieces but do not know whether it is an angel or devil until after the capture. Dartslive Co Ltd produce 3 versions of the board game in different materials, as well as a mobile phone version.
