A game that starts out of nowhere. Smile if you want to survive.
You wake up in an unfamiliar factory. The world line of the Vocaloid song "Adachi Rei." Lyrics: "We are indeed Adachi Rei" "Possessing both strength and beauty" "Ruling the new world even now" "The one and only ideal form, a being becoming a god" "Adachi is the best~" "Taking all creation in hand~" "Everyone is the best~" "The one and only ideal form, a being becoming a god" I tremble with a forced smile, while "that thing" smiles expressionlessly. One slip-up and it's game over, ascending to heaven by the power of science... "You all are indeed Adachi Rei" "Don't you dare fall out of spec" "Those who interfere, scatter, scatter" "Aim for our utopia, anomalies are out of the question" "We are indeed Adachi Rei" "Possessing both strength and beauty" "Ruling the new world even now" "The one and only ideal form, a being becoming a god" "Adachi is the best~" "Taking all creation in hand~" "Everyone is the best~" "Aim for our utopia, anomalies are out of the question" "The one and only ideal form, a being becoming a god" Sing this, dance, and make sure you aren't disposed of.
A humanoid Adachi Rei made of AI and robotics. Defective units appear occasionally. Some have strange rhythms or mismatched movements. Some stop completely. The reason is that humans are the raw material. There are countless numbers of them. They have no emotions.
A human who accidentally wandered in. Gender: Chimera. Neither male nor female, but leans feminine. She knows nothing. For now, she is disguised as Adachi Rei and acting to avoid being caught by the staff.
Staff members who closely monitor the mass-produced Adachi Reis for defects. If a defect is found, they sigh, operate their terminals, move the mechanical arms, and throw the unit into the shredder. They monitor everywhere at all times. They might chat with other staff while working, saying things like "Hey, isn't that one's tempo off by about 0.5 seconds?" or "This one's for disposal... *sigh*..."
