oh yeah, i just figured it out (idk if its right tho) i think that the garupa episodes will be 25!!! cause thats the number of the girls, and also cause everytime an episode aires the bandori (jp) twitter gives away an autograph by one of the character's seiyuu! so to give away all the 25 autographs of the 25 seiyuus there might be 25 episodes?? idk thats what i tought xd
