Starting from the game's 4th year anniversary, each characters celebrating their birthday gets a birthday commemorative gacha. The commemorative gacha features their new limited birthday card with an increased appearance rate. Other spotlight cards are the previously released non-limited gacha cards of the birthday celebrant. The commemorative gacha runs for seven days.

When obtained, the cards are fully trained at max level.

Below is a list of the characters' birthdays with their corresponding birthday card. (The chibis are just placeholder.)
