Present Box

Accepting rewards, completing tasks and the like rewards the player with items or cards. Except for lesson related Producer Points and Jewels, every reward will await the player in their Present Box, found on the main screen in your room. Present Box. Items in the Present Box expire thirty days after first arriving, unless accepted by the player.


  • Since LP/AP restoring items expire a day after the current event ends, and the Present Box has its own expiration period, you can store your resource restoring items in the Present Box until a time where you'd like to use them.
  • On event related rewards, you can prolong the expiration date by waiting until the event ends to accept them. By doing so, you can keep resource restoring items for up to three events. Remember to claim your event rewards before the next event starts and the banner is gone, if the banner is gone any unclaimed rewards are lost forever.

Diamond Shop

Diamonds can be purchased in the diamond shop, which is found on the school map, rewarded in special campaigns like log-in reward campaigns, or achieved by completing tasks in lessons, collecting event points, and reading event stories (1 diamond per chapter).

  • The event BGM and unit song previews can be set as background music on each character's profile page. The main page will also play the BGM chosen for your set character.
