A robot whose mission is to collect data regarding human emotions and report them back to his superior for "Global Illumination".
The center of everything that Hello, world boils down to is –not surprisingly– Kazuki, the protagonist. His mission leads him to start off this journey, from the initial boot sequence which will excite any computer programmer, and computer-oriented thought sequence, to the endpoint where his observation subjects become people he willingly desires to protect despite his logic circuit.
The excruciating details of everyday life between the regular student life and the robotic reports to "HIKARI" will, through the meticulous writing of Shikashi, the writer, seep the subtle changes of Kazuki personifying through tiny things like the time he takes to respond vocally to others, his speech patterns becoming less formal and various neat tid-bits that one can pick up when reading.
