I'm pretty sure there was a 18+ version for the main series. Originally Key visual novels don't have 18+ content, but the series has a special edition that has 18+ scenes with the heroines. I don't know if they're canon though. Setting that aside, the anime was good and as expected of Key of transforming first part of the story from sunshine to rainy clouds in the second part with the last part becoming a rainbow. With that said, I want my Angel Beats volume 2!
I dont know if this serious post or not but its not if that is indicator what you make Kurugaya ? Little Buster is name of gang that Kousuke made when they still children, composed of small group of friend MCriki, Kousuke, his sister Rin and muscleMasaya, and kendoguyKengo Also the original source is VN from Visual Keys who also know by AIR, Kanon, clannad and angel beats. Search it VNDB since i couldn't open it thank to my shitty internet provider and for now kinda hard to use VPN One thing to say, after reading Tomoyo After 18 version i can only say H scene by Keys pretty much meh so i have doubt about LB 18 vers too but yeah it canon by them
The vanilla is too strong and the character designs are too family friendly to get aroused. Well, there are still buyers who get off them. I, for one like Key for their stories than the usual visual novel standard of having sex scenes.
