Nanana Ryuugajou

Оригінальне ім’я: 龍ヶ嬢七々々

The female heroine. Nanana is the ghost bound to Juugo's room since her murder 10 years ago. Unable to rest in peace, Nanana spends all her time playing video and online games and eating her favorite and only food, pudding. She is thus forced to live as a NEET, and although she was never bored with it, she was actually lonely until Juugo rented the room. Living as a human, Nanana was an exceptional student who was extremely adventurous, and she along with seven other exceptional high school students—known as the "Great 7"—founded the Nanae Island project. Her collections were rumored to be a treasure trove of her enormous fortune that she amassed from her treasure hunting adventures. Part of it was used to fund her project, while the rest were hidden all over the island. Among her collections are rare and mysterious artifacts that contain magical properties.
