I wanna start reading this guys.. can someone tell me if the main story is finished ?

Not finish

yes, there is a creators note and special episode on b@to that never got uploaded here. if i remember correctly there are gonna be side stories in the future

Interesting. Seems like chap 47 is the last one of the main story ? I guess I will marinate this for a while longer... I mean I already waited this much, I can wait for the side stories too
