This is the BEST ecchi anime I have ever seen, and trust me I have seen many. Good opening, wide variety of characters and superb ecchi scenes make it a must watch. The main advantage of this anime is that each episode is only 8 minutes long. One of the rare anime which delivers what it promises. ALL types of girls including tsundere , deredere , loli etc are included! It also has a decent story and some scenes will make you unable to contain your laughter. The ending episode is extremely good and will leave a warm feeling in your heart. I recommend you to not think muchand just ignore the rating and watch it, cause such anime are very hard to find!
