Yes, we are providing a Custom nickname setting function where you can set different nicknames by ARTIST.
If you did not do Custom nickname setting, the ones entered into the default bubble profile will be applied to all chat rooms with ARTIST.
※ How to do Custom nickname setting: Click 'bubble chat room' > 'See more' at the top right corner > 'Chat room settings' at the bottom > 'Custom nickname setting', type your desired nickname and save it
You can turn ON/OFF the Custom nickname setting function; when you switch it off, the nicknames entered into the default bubble profile will be applied to all chat rooms with ARTIST.
You cannot change your nickname called by an ARTIST in a message that you have already received.
The nickname set for each ARTIST can only be applied to the messages received after completing Custom nickname setting.
