Jede Musiknote in der Partitur

Can someone explain to me: is Mikeko a fanon thing or Spirit of Justice thing (which I have yet to play because I’m behind on everything)?  The cat is everywhere and I’m not sure where he came from…  (I love him, I'm just confused by poof!magic cat.  I didn't even see Trucy.)
