The initial idea was that the only one who would be in character would be the one playing the role as "Scrooge". The others would be playing as their respective ghosts who have only taken the form of who is playing them.

The role of ghosts could also be:
Past: Philomel as the one who understood who he was.
Present: Storm as who currently knows Shin in the present.
Future: Sage as he is someone Shin has yet to meet.


Maybe?

Why do i always get unconventional ideas?
