Unless there will be a crossdressing, cosplay-fanatic, android cat/insert-animal-of-your-choice- girl with Emi's height, Shizune's face, glasses, drill hair that is covering half her face, big boobs that can be deflated before intercourse, with Lilly's manners, part of Hanako's and Emi's behaviour, Rin's humour, who is a childhood friend of the main character and an apparition of his dead older sister and who is governed by two polar personalities, possessed by the devil and an angel simultaneously - making her sometimes appear like a dark-skinned or albino girl respectively and who is by some kind of coincidence having a deadly illness and must be saved by the protagonist from some kind of ancient evil and who has all kind of disabilities and mutations - ranging from one missing finger to lepra to tentacles and to death and who is moe and a yandere and all the the crazy other personalities and stuff fiction has blessed us with there will be people who are unsatisfied.
However nobody is inclined to accept that fact - people who are in need of this can make their vision come true but they should do it via their own devices and should not demand other people to fulfill their wishes.
All of us here have been lured into the story because it entertained us so well. And while I can think of additions that would make the story more suited for myself I am very very content with the vision the developers have given me. I may not agree with everything but the whole of Katawa Shoujo as it is now is good enough for me (strong understatement here) and more than I would ever expect from an independent small team as their first product.
If you are not happy with the ending of a novel - turn to fanfiction and the same is true with KS - write down your version why and how Hisao and Misha should become a couple and post it on the fanfiction forum here!
Remember kiddies; "Misha must die!".
And also remember from our previous lecture, kids:
"LET THERE BE BLOOD AND NOTHING ELSE BUT BLOOD, BECAUSE DEATH IS A BEAUTIFUL THING!"
Ahh, Morticia? I would die for her. I would kill for her. Either way, what bliss.
