While reading Tsutomo Nihei's Wikipedia page, I came across Blame Academy.
It's a rather bizarre parody of Blame! in a school setting, though it's still set in the same world.
It's in FULL COLOR! :D
There's only three chapters so far, and they are published rather sparsely.
The stories are pretty brainless and obvious fanservice, especially in the third one (boobs! panties!). I didn't really like it that much, but it's pretty interesting seeing the characters so... different.
What do you guys think about it?
It's not hard to find if you want to read it, but I'm not posting links.
