Though we cannot say definitively, it is highly unlikely any past ColorFes gachas will get reruns. The 1.5 Anniversary ColorFes is an exception; Since ENSekai does not release new cards or gachas for anniversaries like JP does, there are special reruns like this one instead. Whether this will happen again for future ColorFes is also unknown. However, it is possible to obtain Airi and Haruka’s ColorFes cards in every ColorFes gacha, including the rerun coming soon!
