The types of activities and characters that can be interacted with vary depending on the day of the week and time of day. Additionally, some activities are limited by the protagonist's three attributes; Academics, Charm, and Courage, which can be built by performing various activities or making certain correct choices.[2][3] During the evening, players can choose to visit Tartarus, the game's main dungeon, where they can build their party's experience and gain new items. On the day of the full moon, players will participate in a boss battle in order to progress the story.[4]
