Demon Angel Sakura -The forbidden mirror- http://www.dlsite.com/ecchi-eng/work/=/product_id/RE136066.html This game is true gyaku-ryona. I think you play as a male angel named Sakura who was sent to the demon world by Anastasia to defeat large female monsters. The game plays like a boss rush because there are no zako. You move with left or right, crouch with down, and jump with up; you can also stay in the air up to five times by pressing up while in midair. S is your attack, and A is a manual charge for your shot where you can build up at most five shots in one. The demo only has the slime boss who shoots slime and jumps across the stage. If the player loses over half his health, he loses his clothes, and the attacks from the enemy change. If he loses all his health, a close-up with the enemy happens where she has her way with the player. It's not too often a gyaku-ryona game appears that's not a role-playing game.
