Congratulations on the milestone! 
I have 75 episodes of this one, BUT I'd say the reached milestone of 50-65, because I put ads of my Patreon in-between stories. 
But this is my darling. <3 40 episodes, but most important for me was that I finished the flashback arc, which took 11 episodes out of these 40! It felt like it took forever, but now arc is over, characters introduced and I can move again...Till next long arc. X)
