Earlier today we received an update it includes the ability to change the home screen music, mute music while viewing character art and listening to their voice lines.

There is also a new area in the Tower of Babel called Past Century Memories. After a battle you can see the total time, number of turns, and the total damage dealt and by who during the results screen. There is currently only one Quest and they're no rewards for clearing the quest for the first time.

Charge Skill Evolution has been added! It only requires the character and Spell Tokens corresponding to their Attribute the cost is 15, 20, or 25 based on rarity. The CS keeps it's base effect but adds new ones. Characters can have different effects based on their rarity. These Quests do not have a battle and you get 10 Guild Alliance Certificates. (Honestly this could have treated like a standard Level/Limit Break instead of adding a new area in the main map)

Quests have been added for the following characters and their new CS effects. They're also featured in a new banner and it seems there will be a part 2 later

Oniwaka 3star Remove Buff from hit enemies. 5star Remove Buff from hit enemies. Inflict Break to hit enemies and those to the left and right of them

Licht 3star inflict Possession on hit enemies. 5star inflict Possession on hit enemies. Inflict Weakness on hit enemies and those to the left and right of them. Valentine heal allies within a 2 space diamond radius up to 600HP
