Juugo
The story's main guy. Juugo's got endless energy and an obvious weakness for girls, though his actual love life is pretty much nonexistent. Despite Nanana being a constant headache—literally living in his room and causing chaos whenever she feels like it—he genuinely wants to help her move on from whatever's keeping her tied to this place. He's actually invested in figuring her out, even when she's being difficult.
He ends up joining the school's adventure club, which gives him a solid excuse to explore the island while hunting down pieces of the Nanana Collection. It's the kind of thing that seems perfect for someone like him: adventure, mystery, and the chance to spend time with interesting people. The club searches become his main focus, and they tie directly into his goal of helping Nanana find peace.
