Responsibility - limitation. Irresponsibility - removal of limitation. This is the principle by which the not quite bad and not quite good characters in this story live, who tend to confuse the concepts of this principle for their own benefit. The story begins with a less responsible character, who is not quite organic, and for the most part beaten off on one hemisphere of the brain bio-android nicknamed Naid-i, who likes to complicate his life with his ill-considered actions, and likes to wear a rubber mask with built-in rabbit ears. The adventures of this character begin with a close acquaintance with a criminal gang called "45 Stadium", which includes especially distinguished in its cruelty natives of the sports institution with the same name.
