Dark humour... For mortal like us, seeing suffering death scene with this drawing style and science description monologue is like someone tell you horror thing with mocking tone. My emotion was so confused in that sacrifice scene, I feel like laughing and crying at the same time.
I wonder why are there so many haters here? Is it perhaps because of the author other mangas? Don't wanna judge the whole manga before it ends. The chapters so far are pretty good, though.
Came for the yuri, stayed for the plot.
