Binan City is located in the northern Kanto area of Japan. At Binan High School, the Earth Defense Club (lol) was a group of students who didn't do anything productive. Kyoutarou Shuzenji, Ryouma Kirishima, Nanao Wakura, Taishi Manza, and Ichiro Dogou often had pointless conversations over tea during their meetings. One day, after school, the boys gathered at Kurotama Bath. Ryouma noticed that Kyoutarou was enjoying the hot water a bit too much and pulled him out. To their surprise, a pretty boy in strange clothing appeared along with Kyoutarou's towel. Soon, the five boys found themselves in a battle for the heir of the magical kingdom, Honila Land...
