Nanana's Buried Treasure (龍ヶ嬢七々々の埋蔵金 Ryūgajō Nanana no Maizōkin?, lit. "Nanana Ryūgajō's Buried Treasure") is a Japanese light novel series, written by Kazuma Ōtorino with art by Akaringo. Enterbrain has published seven volumes since January 2012 under their Famitsu Bunko imprint. A spin-off light novel series titled Ikkyū Tensai no Kiwamete Fuhon'i na Meisuiri (壱級天災の極めて不本意な名推理?, lit. "Tensai Ikkyū's Reluctant Deduction") is also published under Famitsu Bunko, with the first volume released on August 30, 2013. A manga adaptation by Hitoshi Okuda began serialization in Enterbrain's Famitsu Comic Clear web magazine in January 2012. An anime television series adaptation by A-1 Pictures began airing from April 10, 2014 on Fuji TV's noitamina block.
In July 2014 Nozomi Ōsaka, under penname Non, replaces Akaringo as illustrator for the original light novel and its spin-off due to Akaringo's health condition. Akaringo stated that his health declined, and which is why the illustration for seventh volume could not be finished. Due to this, the decision was made to replace the illustrator in both projects.
On the "Special Student Zone" artificial island – Nanaejima, the story centers on a beautiful, optimistic, but NEET (not in education, employment or training) girl Nanana Ryūgajō, who was mysteriously killed in her own apartment.
Ten years later, a boy named Juugo Yama was forced to transfer to a high school on the island. With only a certain amount of money to live on, Juugo chooses a low-rent apartment that happens to be haunted by the ghostly Nanana, who is bound to her former home and unable to move on. Juugo and members of the school's adventure club join a "treasure hunt royale" on the island for the Nanana Collection, treasures that possess mysterious powers.
- Jūgo Yama (八真 重護 Yama Jūgo?)
- Voiced by: Yūki Ono
- The male protagonist, Juugo, is an energetic student in his second year of high school with strong stamina and endurance as well as a fondness for girls in maid outfits. He is devoted to helping Nanana move on, in spite of her constant commotion in his room, as he tries to find interest in her. Juugo joins the school's adventure club on a hunt for the island's Nanana Collection. It is revealed he's secretly the heir of Matsuri, an ancient "noble" thief organization that claims to only steal from the wicked, but was banished to Nanae Island when he refused to take the position due to a difference in ideals. Juugo claims he does not believe in doing things for others, and does not believe he'd give everything to help anyone. Despite refusing to take the position, Jūgo is actually quite good at stealing treasures, and managed to outmatch Tensai, Isshin, and even other Matsuri members a few times, although Tensai usually deduces it in the end. Jūgo's Nanana Collection is a large jewel that allows its user to tell when others lie when looking through it, which originally belongs to Ikkaku, but Jūgo intercepted it when Matsuri members attempted to steal it, and gave them a fake one later.

Her remaining treasures and property become the islands' greatest secret following her death. As an adventurer, Nanana knows all of her treasures' hidden locations, the trap protecting them, and their functions, but refuses to tell them, considering the secrets and risk a part of the precious experience.
