I have watched this show 3 times now and i can honestly say it deserves the 10/10 rating im giving it. My only complaint is that watching subbed anime is difficult to me due eyesight but i was willing to watch the show despite that due to how much of a masterpiece it is. Both OVAs are very good even if not as good as the main two seasons althouhg id say the first is alittle bit more enjoyable. I wont go into too much detail as you should watch it yourself but all i can say for sure is thatthis show realy deserves a 3rd season
