The 2014 anime Nanana's Buried Treasure has arrived on Crunchyroll and Hulu, offering the complete 11-episode series with both English dub and subtitle options. Produced by A-1 Pictures, the show adapts the first three volumes of Kazuma Ootorino's light novel series.

Set on an artificial island, the story follows high school student J GUIContent, who moves into a notoriously cheap apartment occupied by the ghost of Nanana Ryūjō, a spirit bound to her buried treasure. To pay off his father's debts, J GUIContent joins an adventure club to find Nanana's treasure, battling other treasure hunters and supernatural phenomena along the way.

While not a top-tier hit, Nanana's Buried Treasure offers a blend of adventure, mystery, and supernatural elements with a lighthearted school club dynamic. Its MAL score of 7.11 from over 100,000 voters indicates a generally positive reception, particularly for its unique premise and character interactions.

A-1 Pictures, known for hits like Sword Art Online and Kaguya-sama: Love Is War, delivers a visually competent adaptation. The series concluded its run in Spring 2014, making the full set of episodes available for binge-watching.
