I am alone in saying i liked Shizune's route and i really enjoyed that story. I've beat Hanako's as well but it something about Shizune lol never forget your first i guess
Definitely have to go with RIN. She had a really touching story, made my eyes leak a bit lolz. I haven't even been motivated to do the other girls route's because i feel like i will be cheating on RIN lolz.
Hanako is my favorite for sure. I related to her more then the other girls. Though as much as I like Lily I never really met anyone like her and her path while I enjoyed it was very predictable.
Hanako hands down. When I first saw Katawa Shoujo I really liked her design and a few years later now the game is now done, I love her character in the game she's my no.1 girl.
I've only done 4 of the girl's routes, but Emi is the girl I most relate with. Being too stubborn for one's own good is a problem that I am more than familiar with.
I would have to say that Lilly was my favorite girl and I feel her route got a bit more love what with the ending and whatnot. Credit to Rin's route though for being something completely different from what I expected though.
