Angel Beats and Clannad for me...
(no spoilers ahead more than the 1st episode)
Angel Beats is about an afterlife instance where you go after you die... Its a beautiful idea to believe and also a nice message... (i dont want to go deeper)
Clannad on the other hand... an anime with 50 episodes (Must watch clannad and clannad after storie)
Kinda a slice of life.. where you see some kids having normal lifes with some overnatural stories... In Clannad After Story, shit gets way more serious since this kids with no resposabilities, grow up and become adults..
It's long but it's worth since you can get more familiar with the characters.. Also,for me, one of the greatest plot twits ever in anime... around 50 episodes, no more than 5 words and holy shit...
Some more realistic and crude anime about war in japan... The grave of the fireflies... I didnt cry at it because I felt it pretty distant from me but a crude war story
Also a very nice anime with super shitty powers to watch: Charlotte
Give this one a chance, i have it on my 9/10 animes
