AI no Idenshi

Humanoids have become a normal part of society, possessing bodies and minds remarkably close to those of humans while suffering illnesses and problems ordinary medicine was never designed to address. Doctor Hikaru Sudou treats these patients, from memory disorders to requests that could alter personality itself.

Every case raises a question with no simple medical answer: if a mind can be copied, repaired, or rewritten, what makes a person the same individual? Outside his legal practice, Sudou works under another name, performing forbidden procedures and searching for information connected to his missing mother. While helping others live with the limits of technology, he moves closer to a truth that may make questions of identity and memory far more personal than he wants.
