This is a really interesting manga, in that, it feels like some seminal work due to its size and potential (and, genuinely, there is some very good ideas in here) but it just...isn't. Like it feels like nobody has read this, nobody saw the movie, and those who saw the movie certainly didn't like it. 

It feels a shame, really, because there's so much in this to like but an absurd amount of time is spent talking about unbelievably boring things, and not in a way where it feels like you're getting into the minutiae of the characters and seeing them as whole people, as much as it feels like you're watching characters perform the trope (albeit realistic for their age) that is predictable and ultimately dull.

The things to like, however, is Nanako. I simply love Nanako, I love robot characters and I love her very much, thank you! I think her design is great, I love the conflict of not being able to confide in her because she is a robot and thus compelled to tell the truth, I loved the discussions about AI lying and what that implied,

and I loved how she chose to keep her memories and be separated forever

. THAT IS SO COMPELLING! SO WHY WAS I SLOGGING THROUGH THIS THING?!

I don't think Break of Dawn is like some hidden manga that people gotta check out but I do think it has the foundation of something good that was kind of squandered. Imagine if Naoki Urasawa wrote it instead...sigh, well, anyways, Nanako thank you for making it like sort of worth it.

And yes, before you ask, I will watch the shitty movie where Nanako looks awful, don't worry. I'm nothing if not a completionist. Anyways I'll be looking forward to that cock and ball torture for sure!
