My goal is to create a space where young people can strive towards achieving their dreams! A team of seven brilliant students, known as the GREAT 7, embarked on a project to construct Nanae Island, an artificial landmass, with the intention of fulfilling the whimsical idea of their leader, Nanana Ryugajo. Fast forward 12 years, Nanae Island now boasts a staggering population of 100,000 people, with 80% of them being students. This island paradise is now known as a student haven. Recently, a young high school student, Jugo Yama, was forced to move to Nanae Island after being disowned by his father. Fate took a curious turn when Jugo discovered the ghostly presence of Nanana Ryugajo, who had been murdered 10 years earlier. With this unexpected and unusual housemate, Jugo's plan to live alone was thrown out the window. The novel, "Nanana's Buried Treasure," written by the same author as this anime, won the Grand Prize of the 13th Entertainment Awards, the first Grand Prize in eight years. The anime follows Jugo Yama as he searches the historic ruins of Nanae Island for Nanana's Collection, a series of treasures with mythical origins. Along the way, Jugo meets fascinating characters and solves intricate riddles, making for a thrilling adventure full of exciting treasure hunts, strategic battles, and boundless excitement.
