Gameplay
The player starts as Akatsuki, a girl who can't go out of her room. The goal of her campaign is to explore her dream and collect all 13 effects. There is a note book on the desk in Akatsuki's dream room the player can interact with. It will show sketches of all the effects the player collects, and you can drop the effects by interacting with the sketches.

There is also an unlockable character named Hanatsuki. She can be unlocked after completing some tasks in Akatsuki's dreams. Hanatsuki's room has 2 doors. She can enter the Nexus directly from the door on the right. The sketches that let you drop your effects will appear on her balcony's floor. You can't equip effects in Hanatsuki's room.
