Episode Title:
Break Through the Monkey Hot Spring!.
Episode Description:
Haruhiko talks about how humans have used hot springs for leisure and for the health benefits for thousands of years. A gang of Phantom Monkeys transform the school grounds into their own Hot Spring which is guarded by a large perverted Monkey Phantom so no one else can use it. Every attempt to defeat the Phantom fails and even Haruhiko is unable to seal the Phantom with his sketch book as he cannot see the Phantoms feet underwater and therefore cannot draw them. Attempts are made to lure the Phantom out of the water using girls in a variety of revealing outfits, but the Phantom isn't attracted to any of them. The Phantom is eventually lured out by Mai but Haruhiko spills paint on his sketchbook and is still unable to complete the drawing, instead summoning the octopus demon Cthulhu to trap the Phantom so Koito can sing it into submission. Before they finally defeat the Phantom, Haruhiko learns the Phantom was just upset that his wife had left him. To cheer him up they hold a fake wedding for the Phantom with Haruhiko playing the unfortunate role of the bride. The Phantom departs with Haruhiko in tow and the hot spring disappears.
