Burn, Super Combination!. The episode opens with a distinct sci-fi feel, before moving into the game, where the Ishiyama group are in the middle of getting their asses handed to them. They are unable to do anything against the tank. Then Yuka shows up, driving a giant robot called the Crazy Frog. She crushes the tank, and proceeds to kick and tap dance all over the other vehicles. Up until she steps on a mine and loses the tank. Tatsumi's training goes more like an aerobic workout, complete with lame musical accompaniment. He complains about this, calling out for being an exercise, and not training. Meanwhile the gamers run into more trouble when En's team start using an invisibility cheat. Himekawa realizes what they are doing, and goes to prepare some countermeasures. While Tatsumi does pushups, Saotome tells him that Tojo asked to be trained, and if he isn't careful Tatsumi will be overtaken. Saotome uses a recording of Tatsumi's voice to make a training partner who has all his hidden strength. Only the casette recorde Beel's voice, and they are faced with a Beel at full power. At first Tatsumi takes this as a joke, only to realize that as a Demon Lord Beel has some crazy hidden potential. Problem is he's still Beel, and easily distracted as he takes off after a bunny rabbit. En's maids fixed the Crazy Frog, and Lamia realizes that there is magic at work in the game. The rest of the Ishiyama team is killed, and without their medic they can't get back into the game. Himekawa comes back and reveals that he bought the company that makes the game for the sole purpose of getting them to put in a special cheat for him. He brings their characters back as zombies. En, who had just been allowed to actually play, gets attacked by the zombies, and his forces find themselves without their invisibility cheat, and the Ishiyama students have five Crazy Frogs, which combine into one giant Sentai robot. Tatsumi manages to capture shadow Beel, using his own stupidity as bait. Isa takes Aoi to an inner part
