Tbh i did just two routes on Fruit of Grisaia and then moved to Labirynth whatever you chose is your choice. If you dont like some girl don't feel obligated to read her story you will just know less about her that's all. Story is perfectly explained in whole Trilogy together, one playthrough is enough.

thx

i ask because she felt like the main heroine you have to choose
I have the tendencies do dislike the main ones or the cannon pair in general
Realy dislike Niskoi ending for example
Or best example
I dont like the Asuka route in Aokana( espeacially the sport part)

This question was also important to me. I've only completed Yumiko's route and I don't want to do other routes at all I don't want to see bad things happen to a girl who was given so much time in the first playthrough. That's why I just stopped there and did not undertake to pass this main route, with Amane

By the way, which routes(girls) did you choose?

And if you ended up playing the next two games, what are they about? Of course, if you can answer without spoilers. Yumiko's route looks completely finished. (This is not that a serious spoiler for those who have completed at least one route) Unless the future of other girls is unknown to me. But I know about the past, the present (at the time of the game) and I assume a calm future for the protagonist and Yumiko. When I looked at the screenshots and the description of the next game.. it looks like the same thing. Same school, same girls. Same main character

Labyrint is mainy about Yuis past and a teaser for the next mainline game eden.( Darker or creepier in my opinion than the other stories)
Aditional aome sex scenes with other characters as well eg Chizuru. I did not do the after stories from the others
I did all routes good and bad ending despite the "good ending" from Sasaki (felt satisfied with the bad ending from her) and all the routes from Amane
