Nothing is there complaint, maybe it has a number of sexual scenes so it maybe hard to watch in group (so watch alone). Story and characterization is super awesome and absolutely enjoyable. Must watch anime. Worthy to watch. I am seriously waiting for the next season but so disappointed as next season works are still not started due to some issues with the production company. It will be nice if the production company takes some initiative. It is such a great series which needs some serious attention. It is totally underrated. I am recommending everyone to watch this anime. Headphones are must needed while watching.
