Turn the camera on, she a born star"
(Kanye West - Hell of a Life)
What does this have with Gigant? Well, it's the plot. And aliens of course, it's a Hiroya Oku manga.
Although i feel the sci-fi makes no sense at all at first, it's a beautiful drama i'm not gonna lie, and the MAL score just do no justice to it.
The story really takes a while to get off, probably only around chapter 15 you'll get the hang of i, but then it's really something. The manga has a lot of references to other works by Oku, and a LOT of sex and aliens, but it's expected.
It's an ultraman-esque kaiju fantasy with lots of drama, sex, evsceration, and nonsense. If you love gantz or inuyashiki, you'll love it. I did.
