There are many secrets in Gacha Club that get you in-game currency, such as skill moons, enhancement stars, awakening records, gold, and gems. These can be used to level up units for battle and/or Gacha for units.
GUI Secrets[]
Usalina's Secret[]
When you arrive to the title screen, if you wait long enough, there is a little pink bunny (Usalina, the game's mascot) popping out of the title. Click on her and you will get some in-game currency. You can only claim the prize once.
Options[]
When you go to the “Options” page, look at the top right corner and you’ll see another piece of text called “Options”. Click it and you will get in game currency. Like all of the other secrets, it can only be done once.
Phantom's Eye[]
Go to the Battle menu, and you'll see a rectangle on the very right with the words "Clear Main Story Chapter 2". There is a figure on the rectangle, click his left eye and you'll redeem in-game currency. You do not actually need to clear Chapter 2 of the main story to redeem this award.
Charlotte's Ahoge[]
