So maybe Komachi is just too focused on doing what other people want, and doing it with a smile. That girl has gotta stop making me come up with excuses for her bullshit.
Also, the prez isn't the one trying to kill all these people? I know he was responsible a couple times. But the insane frequency of potential deaths isn't his fault...
Maybe by saving someone, another life is owed. To Death, or whatever. A soul saved for a soul damned. And Death keeps trying to collect.
