He's looked down upon by the other staff around him, and his relationship with Maho his wife, a former nurse, has cooled down. After a patient's suspicious death, he makes a new discovery; when the deadly bacteria "Gift" invades the body, the patient soon dies, but the "Gift" leaves no trace thereafter, enabling it to be used as the perfect weapon to kill.
