There is not a whole lot that is similar between the two animes but there is a bit. In daitoshokan, the main chracter is lighthearted when compared to the main chracter of the fruit of grisaia but the main premise is similar how at one point or another the main mc helps each girl with something they have or had trouble with in their lives also like every anime of this genre all the girls are in love with the main chracter
