Spoiler:

Katsura makes herself a b1tch becouse if she don't do that, she will lose Makoto (She will lose Makoto becouse of Sekai if she wasn' that). I don't know why or what makes Makoto to prefer Sekai and Kotonoha lose him. One day, Kotonoha makes herself a "USO DA!" girl, she taked a knife and kill Sekai.

I've played the game a few times, and on my first try I actually got the Kotonoha saws Sekai ending . If you want to find out how I got it, read spoiler below

Spoiler:

The way I got it was letting Sekai do the tokkun (practise) just like in the anime. Then I asked to continue the tokkun. Somehow we end up at Sekai's place and continue and get a nice h-scene. It's kind of sweet as h-scenes go.

After that I do all the Sekai points actions and none of the Kotonoha points (the way the game works is at certain points you choose an action to do, or to do no action - whatever you do will either fill up the Sekai bar or the Kotonoha bar. This bar shows which girl you are closest with).

This usually means standing Kotonoha up for lunch etc. I also break up with Kotonoha and tell her I like Sekai instead. Kotonoha confronts Sekai and gets really mad. Sekai admits the relationship. Kotonoha slaps Sekai. At this point my Sekai bar is maximum and Kotonoha bar is zero.

Bad things happen to Kotonoha. Kotonoha becomes a stalker and spies on Makoto and Sekai making love often.

Kotonoha finally snaps and picks up a saw she finds outside Sekai's place.

The next day we have the murder scene! Poor Sekai...
