For this episode Arino challenges the much maligned Hudson classic, Milon's Secret Castle. This early entry in the action adventure genre has a bottomless bag of gotchas which Arino has to constantly be aware of if he is to conquer the labyrinthine castle.
To give his thumbs the rest that they so sorely need Arino visits a bathhouse that happens to feature a couple of arcade machines. It's the perfect excuse for Arino to recharge his batteries before his next arduous challenge.
Ring Ring Tactics moves forward after a viewer assists with solving the mysterious code before Arino encounters a new boss.
