Inventory (アイテム) is a main menu function that displays all the items you have earned.
- Owned Items (保有アイテム) - All items that you own. Items must be in this inventory before they can be used.
- Purchased Items (購入済みアイテム) - Items that have just been purchased from the cash stop appear here. They need to be moved over to Owned Items before they can be used.
- Expanded Inventory (拡張アイテム) - Extra inventory space implemented to fit newly introduced items.
- Use Item (使用する) - Available from some items, allows you to use the item.
By clicking on all 3 flowers next to the fairy on the left, a "mini-game" is unlocked.
- This consist of an "Anti-Air Defense" game, where a black sheep (reference to Gotland) is thrown to destroy abyssal planes.
- This mini-game is just here to "kill time", and so is not linked to the rest of the game, neither consuming nor rewarding anything.
