After completing [JT8-2], new skill, artwork and voice lines will be unlocked for Amiya. Details will be revealed in the livestream.
[JT8-2] requires E2 Amiya in order to enter. Level, skill levels, potential and trust level doesn't matter.
4) CC#3 Cinder

It will include new contracts and stages. Limited shop will include new outfits. Completing certain challenges will reward special medals.
5) CoB rerun
Starts early December
Mostima's banner will receive a rerun.
This rerun will inherit all previous stage/first-drop progress.
Certain event rewards that could not be obtained twice will be converted into [Intelligence Certificates]. To check the conversion ratio, please refer to [Intelligence Certificates Converting Rules] during the event.
[Intelligence Certificates] can be used to exchange for items in the Shop.
Gonna take a while before this arrives in EN but I am very excited. Personally guessing Talulah for the new limited character
