The fifth comic: #827 Death Note
A book and a half in, this is getting quite interesting. More of a thinker than the concept may have seemed to be - while also featuring shnigami, Death Note doesn't feature Bleach's battles - it poses some more quandaries - if you had the power over life and death, what would you do with it? Is it okay to kill all criminals that way, or even some of them?
Nothing is really answered quite yet, even if I don't agree with our (nominal) protagonist that his course is the wisest. Then again, it isn't meant to be, and the thriller aspects of it are amazing so far.
