I think Sonichu was already kinda like that. If you remember, Chris claimed Sonichu was giving him advice when dealing with Mary Lee Walsh and was the one who suggested Chris do a Curse-ya-ha-me-ha on her that got him kicked out of college. Even claiming to talk to Sonichu during the meeting.
It's like that episode of Powerpuff Girls if anyone remembers the name of it when one of the students at the school comes up with an Imaginary Friend and the Imaginary Friend keeps messing things up while the person who originally created it takes the blame for it.
It's kinda like that accept little does Chris knows that he is the one making these terrible decisions. Not Sonichu, not Rosechu, not Magi-chan, they just don't claim any responsibility for her actions and refuse to.
