If you are intrigued by darker themes but when you actually encounter them in various works are unable to stomach the horror, this might just be the manga for you!
At a glance Dead tube appears to contain themes to satiate even the most disturbed reader, however in actuality none of the characters have sufficient depth to bring even the most disgusting scenes justice. Ultimately this completely undermines even the most grotesque imagery, and the emotional impact on the reader is therefore limited.
this could be excusable for our protagonists, as the premise does give premise for them being emotionless, however the supporting cast ultimately fails to do this manga justice.
