Okay welcome to paragraph number two where i talk about how funny this show is and you start thinking, (when will this end?). The comedy (and holy shit is there comedy) is OFF THE CHARTS. If you ever watch this and say you haven't giggled, laughed, or even smiled, you are a fucking liar. How could you not laugh every time Immortal Robbie played some of his imouto games? Especially during the episode where Yuuji, Milliela (or however it is spelled), and that one guy walked in on him and he was shouting, "SUCK IT! SUCK IT! YOU SUCK IT FIRST!" I won't tell you what else happened because this is a spoiler-free review, am I right? But trust me when I say if your grandpa watches this whole anime (without dozing off) he will laugh, even an old guy like him. Old people never laugh.
Now we shall talk about the harem. Now I don't remember all their names ("But you said you just finished it a few hours ago. D:" says you. Well you can't blame my memory.) but i can remember that Kazami Yuuji and his harem need to be inducted into the Harem Hall Of Fame. The girls are so....um.....(how to put this without sounding like a huge perv? ( ͡° ͜ʖ ͡°) ) ANIMATED. YES. Their graphics are attractive and they each have their own backstory. They also get an episode dedicated to them too, unlike other shows where the only information you get on the harem girls are from weak flashbacks, which make them seem like side characters, unlike Grisaia no Rakuen where the girls are main characters. I guess you could include Kazami's sister in the harem too since she has a brother complex and that is fine. Even she gets her own series of episodes (three or two as i remember from Grisaia no Kajitsu) explaining her disappearance.
Last topic, I promise. The story is so good. almost half the episodes are dedicated to Yuuji's past and that is okay. I'm pretty sure everyone was curious about his past as well. It explains his personality. It doesn't cover his child years i think. As I can recall that was probably in Grisaia no Meikyuu.
Okay I'm sure you have something else to do with your life. I do too. I will end the review on this note: Grisaia No Rakuen is a good anime, the whole Grisaia series is a great series. If you are looking for something to watch at the moment, you have found your anime. It is worth your time and if you can watch it without dying by laughter you will see how great it was.
P.S. I forgot to mention how good the opening and ending are.
P. P. S. Also, unless you are comfortable with seeing boobies uncensored, DON'T WATCH THE SPECIALS. They are basically soft-core hentai. While creating the specials the creators were ONE STEP away from crossing into hentai zone. I endured through them though. ( ͡° ͜ʖ ͡°) there is no censored version too so if you don't like hentai don't watch it.
