Instead of using Play Points, you use "Daily Live Chances" to play Daily Lives. You get 3 Daily Live Chances per day, resetting at 04:00 JST.
Subscribing to a Membership grants you an extra 3 Daily Live Chances per Membership, for a maximum of 12 Daily Live Chances per day if you have subscribed to all three Memberships.
You may refill your Daily Live Chances once per day using SIsCa (40 SIsCa for 1 Daily Live Chance).

You can refill Play Points by consuming your unused Daily Live Chances for the day (50 Play Points per Daily Live Chance).

※ despite the reset and Quest change being at 04:00 JST, you may not be able to see or access the list of available Daily Quests until it is 04:00 in your timezone as well.
