Spoiler's kinda .So my theory is ok it was kinda obvious from some point that the "it" the machine is somewhat connected to the protagonist since he teleport him from probably another galaxy timeline or even a reality so my theory is this the machine don't remember it name is the same as the mascot so basically the mascot is the avatar of the machine it takes form and wants something from the protagonist probably a fragment of it somehow got mixed with the protagonist and the mascot seems to develop little by little like an ai now it can speak so yeah thats my theory what do you think?
