A special unaired episode included in the 7th DVD/Blu-ray volume.

Conan was the only child born on Remnant Island, a place settled by a group of refugees while they fled a terrifying wave of magnetic bombs that wiped out most of humanity. After 20 years, most of the castaways have died, save for Conan and the wise old man that raised him. Believing Remnant Island to be the last inhabited place on Earth, Conan is shocked when he discovers a young girl named Lana washed up on the beach one day. Though he is thrilled to learn that humanity has survived, Lana tells him the nation of Industria wants her as a hostage to force her grandfather, Dr. Lao, to power their machinery. Their conversation is cut short when Industria's top pilot, Monsley, suddenly appears and seizes Lana. Determined to save her, Conan immediately sets off from Remnant Island and begins a journey that will ultimately determine the fate of the world.

8-year-old Hiyori, who lost her parents, and Yui, seeking to escape her violent father, got off at a Kitsunezaki station one day. The great earthquake and tsunami had changed their destinies. Their lives were saved, but they were perplexed when asked about their identities at an evacuation site. It was an old woman named Kiwa Yamana who lent them a helping hand. From that day, Yurie was known as Yui, Moeka as Hiyori, and together with Kiwa, the three women began a wonderful communal life together at the old house Mayoiga overlooking the sea.

Students at the Houjou academy are perfectly normal—except for those who take the Kuge course. This special course is reserved only for elite and rich students and their honeys. Hagino Yuzuru enrolls in the course through Kai Renge, and she quickly regrets it. To become a honey, a student must get someone already in the Kuge course to sponsor her. Kai becomes Hagino's sponsor, getting her into the course and paying the price to cover it. But in return, Hagino must submit to him as her master, catering to his every whim. Hagino may have gotten herself into something she can't handle. But if she pulls out now, she gets expelled from the school. Can she make things work with Kai, or will she call it quits before he does something she'll regret?
