Six years ago, the right half of a corpse was discovered under mysterious circumstances. The left half was never found...until six years later, when it was discovered completely fresh with no signs of decay, as though the victim was alive until just recently. Now, newly-appointed Special Agent Mizuki and her AI partner Aiba are tasked to solve the bizarre Half Body serial killings... Characters: Mizuki Okiura: ABISs new Special Agent (Psyncer), VA: Corina Boettger A Psyncer who uses the Psync machine to infiltrate the brains of suspects and key witnesses. Mizuki lost her left eye and is now fitted with a replacement eye equipped with advanced artificial intelligence (the AI-Ball "Aiba"). Despite still being a high school student, her strong physical abilities and clever mind have earned her a special accommodation in ABIS. Aiba: Assistant Investigator, VA: Erika Harlacher An autonomous AI that usually takes the form of an eyeball residing inside Mizukis left eye socket. Her job is to assist Mizuki during investigations by connecting to networks to gather information and using special functions such as X-ray and thermographs. Because she has been working as an assistant investigator for a long time, she is adept at reading human psychology and emotional states. Kuruto Ryuki: ABISs new Special Agent (Psyncer), VA: Stephen Fu A rookie investigator with a strong sense of justice. However, he is not the hot-blooded type; he has a reserved and gentle nature. He is a well-educated young man. Unfortunately, both his parents and his brother have passed away... Fighting through his painful past, he aims to solve difficult cases with his partner, Tama, who is implanted in his left eye socket. Tama: Assistant Investigator, VA: Anairis Quiñones Like Aiba, she is an AI-Ball equipped with advanced artificial intelligence. She is usually found in Ryukis left eye socket and supports him in his work. She has a motherly quality to her, being both stern and kind (although she is 90% stern...). She inspires Ryuki by whipping his ass into shape. Purely coincidentally, she is also a sadistic character who literally enjoys whipping ass. English and Japanese voice track.
