A brief and entertaining one-shot for those who understand firstly that this is bizarre and explicit. Other reviewers seem to feel that there's nothing going for the story meaning-wise to justify, in a sense, the goings-on. It's one thing for a manga to entertain through strange happenings, but when a manga attempts to directly philosophize it and bring meaning to it, the audience suddenly shrinks. I'd actually wager that if the mangaka took a more subtle approach it might've connected better with people, as while we all understand words on a basic level, we don't all understand things well through the same use of them.

Anyways, "The Voices That Call Me" is a mild exploration of the "hikikomori", which is a person who chooses to live to themselves within a room - their finances sustained by another. This story in particular explores the basic idea that every human being seeks companionship, but that through the experience of a hikikomori they grow to only really care about themselves. The hikikomori's search for companionship shows how although they want interaction, it's down to a physical level. We're social creatures, so it goes to show how much of an outcast this hikikomori truly is, even if he leaves his room right now. It goes to show they can't re-enter society without assistance.
