Chat

Chat is a text messaging application that can be accessed via the 2nd left-sided icon on the original homepage screen. Here, MC receives messages initiated by characters with the D.D.D. and can interact with them at the users' own time. New chats are acquired as the story progresses or upon obtaining selected new cards. MC also has a special ability to view messages between other characters unbeknownst to them.

Chats can be replayed via the Memory Box button once users have tapped into the conversation.
