I want to level up so I can use the RC I bought for myself, but my level growth feels stagnant. When I asked about it in-game, they told me about a cat that goes on my head that increases my EXP gain. However, I cannot find it: not in my inventory, and not in the store. Where can I find this cat?
See attached; the item is called Black Cheshire. It can be found in the store under Accessories then Waist. There is no need to rush leveling up in the game's current state.
