"Well, time to wipe that fourth wall off the face of the cosmos," Producer says as she starts explaining.
"The Producer character is, in reality, a first-person protagonist character with no true face or appearance, a blank slate to select options and interact with the world of idols. The better world of idols. Not the one with the School Idols. Anyways, there are many of them in a single depiction of the world alone. There are many depictions of my universe, and while the idols are always a constant no matter what, there is a good chance the Producers are different."
Producer takes a good breath before continuing.
"Before Mouse King stabilized me, The P-headed form I assumed was somewhat of the 'blank slate' I spoke of. It is a very popular depiction of the Producer character in various media when you wish to depict them in a more cartoony manner. It is possible that my current personality would've faded away if I remained like that, replaced by something more composite."
