Midori tries to cook for Akemi and ends the world.

More seriously in a regular bad end Midori probably wouldn't kill Akemi, only herself. Which is... horrible enough, really. It would take things going even worse for her to kill Akemi too. It would be like an extra bad end.

... Actually there are kind of multiple bad ends for poor Midori, which features her basically deciding everyone but her, Akemi, and her family needs to be murdered and other really terrible things.

And I reeeeeaaally don't want to do any of the potential bad ends. ^^;
