"Even when the world starts to shatter,
we go on;
unknowing,
unrestrained,
unwilling to change it.

Sacrificing all we have
for a greater whole,
even when we know that all the world will do
with its newly found so-called glory,
is turn back into itself once again."

In a post-apocalyptic future, the only way human kind can survive is with the aid of a higher human-like species, referred to as "Lethestial." They feed off of humans, but in exchange, help with resources and protection. Mori is a 24-year-old agent of BlackBird, striving to find a way for his community to break free from Lesthestial control, but when a mark appears on him after a horrific dream, what it instills is a future surrounded by only the species he hates.
*********PLEASE READ:
So far, I'm pretty sure there'll be violence, as it's necessary for the plot. The "BL," I'm still unsure about, but I think it may also be necessary for character development and blah blah. So, here's warning you, this comic/story/manga/whatever does contain mature content! Mature themes, violence, blood, cursing/swearing, etc !
