Nanana collections are treasures usually enforced with mythical powers, hidden throughout Nanae Island. Nanana collections are usually encased in a treasure box, to obtain a Nanana collection, one has to pass through obstacles and traps. When all obstacles are cleared the Nanana Collection will be reachable and all traps will deactivate.
Eye of YuguthosEdit
Crystal The first Nanana Collection shown is a 'Light up if lie' crystal.
It's was first shown in a black box which ended up in an alley after an attempted theft for the crystal. The ability of the crystal is shown through looking through it. If what the person telling you is a lie there will be a presence of dark aura around the liar, if not lying there will be nothing around it. Nanana calls its the Lustrous Lie Detector (at least in the anime).

The collection was hidden in a trap activated room (a classroom) treasure box with the numbers 777 pinted on it. It was an entry test for new Adventure Club members to complete the obstacle in the room.
