Nanana's Buried Treasure

Synopsis

On Nanae Island, a man-made refuge in the Pacific designed to foster young talent, high school student Juugo Yama finds peace after being disowned by his family. The island, created by the legendary Great Seven, serves as a haven for youths pursuing their dreams. Led by Nanana Ryuugajou, the Great Seven envisioned this paradise as a future for the next generation. After moving into his new home, Juugo meets the ghost of Nanana Ryuugajou, who remains bound to the island due to her unsolved murder ten years earlier. Before her death, Nanana hid various artifacts imbued with extraordinary powers across the island, known collectively as the Nanana Collection. Motivated to uncover the truth behind her murder, Juugo teams up with the self-proclaimed "Master Detective" Tensai Ikkyuu and her androgynous maid, Daruku Hoshino, to search for these treasures.
