The story takes place in a city rumored to have an endless number of levels. In a restricted area, levels are stacked upon each other so much that it's impossible to distinguish the sky and ground or determine which way is up or down. Perhaps the main goal of this narrative is to reveal the secrets concealed in this world and time. The mysterious main character, Kirii, searches for the "Net Terminal Genes," which are still unaltered, with a unique mission and a heavy burden. This quest is the vital point of the story, as it unravels the mystery. The first six logs concentrate on Cibo's story, which was not fully developed in the original story. Cibo, who accompanies Kirii, gathers data from an abandoned disc as they wander around. Whose "memory" will he acquire? It should be noted that these clips are an add-on to the Manga and should not be misunderstood as a plot. They are brief animated scenes extracted from the Manga.
