PARQUET — in the near future, a technology called the brain-machine interface will connect the brain and machines. This technology creates a new paradigm and opens the door for digitization of human memory itself. From these new discoveries he is born. An illegal experiment mixes thousands of memories in one vessel, creating a completely new creature. Having only memories of others, doubts begin to arise in his mind as to who he really is, until he has the courage to go out into the world in search of his true self. Entering the real world, he meets two girls, Kido Tsubasa and Ibaraki Reno. Both good souls, whose lives were disrupted by unscrupulous experiments with BMI, like him. Learning to live with his secrets, he and they will bring big changes.
