Aniimo's developers have detailed two separate batches of free rewards players will receive when the game launches on 15 September. The first set is tied to pre-registration milestones, with rewards unlocked based on how many players signed up in advance; the second is a distinct launch campaign offering additional items to everyone who joins the game, adding an extra incentive around release day.

The pre-registration scheme had four milestones, each unlocking exclusive items, and as of writing the top threshold of 30 million sign-ups has already been reached, meaning every player who joins on launch day will receive all four rewards. Anyone who pre-registered via the official website also receives a bonus Susata Egg. Separately, the launch campaign offers four free outfits, though these are tied to progress in the story campaign rather than being available immediately.
