Kazz Umezu, the author, had once stated (I think in the interview in the back of volume 11) that many of these elements in the story haunted him as a child- and still do to this day. This is a ludicrous story, it's absolutely insane, makes close to no sense, yet it doesn't make fun of itself, even in spite of its absurdity.
And yet, people overlook the fact that, as adults, we'd find this stuff 'kind of creepy' now, if we were Sho's age or younger when we read this (I actually was a 6th grader when I first read through this!), we'd be shocked, horrified, probably lose sleep for days. The point of Drifting Classroom is- it's a childish tale, pure and simple- it doesn't have to make sense. That's the whole point- Sho is still a child, he's telling this from his childish POV, this story is about (really) being able to connect with that guillibility of youth, the untouched innocence that we all once held- Sho and the children are able to survive because they're still young, and able to accept these things- they make no sense to us adults/older people- but to these young kids, who are able to adapt to the most hellish surroundings, they are quickly able to accept their fates.
This is a story that forces you to think about what you feared as a child- your parents disappearing forever, being thrust into a horrible scary nightmareworld, being attacked by monsters, being left alone and forgotten...That's what Drifting Classroom is REALLY about. Not blood, not gore, not "omg Y IT DOES NOT MAEK SENS TO ME!111!" this is a true horror story- the fears we all experienced in our young lives come alive here.
It's a good manga- really absurd, and practically ZERO logic, and I'm rereading the series- it's addictive and quite a fun escape from reality.
