I have finished 3 three different endings, one with Kazashi, two with Sakiko. All paths that I had chosen were ending with plot twist actually. Personally, I enjoyed all of them. The most shocking was the Sakiko's (SPOİLER ALERT***) homicidal ending.
But my favorite was Kazashi. I have seen my insecurities in her. Thank God I had gone through a break up before playing this path. Otherwise I would build a fucking cell in my house or something.
I am thinking about playing Yoko's path too. Let's see what that little gangster has got.
