In the second season of Binan Koukou Chikyuu Bouei-bu Love!, the Earth Defense Club is comprised of typical teens who exhibit a penchant for laziness. Rather than actively defending the planet, the club often lounges around at a nearby bathhouse. However, everything changes when a pink wombat suddenly materializes and implores the boys to assist in saving the Earth. Despite their usual idleness, the high schoolers quickly spring into action and employ the power of love to transform and protect the planet.
