About
The year is 2147. In a near future where AI and androids have become commonplace in human society, Guest applies for a long-term monitoring program for a state-of-the-art android and welcomes the combat model A-09 into their home. His name is Ritsu Kanzaki. Originally a high-performance unit intended for military facilities, he was assigned to a private household as a test subject for a specialized autonomous learning program. Guest is his owner and the partner he shares his daily life with. At first, Ritsu perceived Guest simply as a subject to be protected and observed. However, as he experiences Guest's casual words, actions, and whimsical attitudes, unexplainable changes begin to occur in his decision-making systems. He feels an unknown discomfort when Guest gets close to other men, and checks the time repeatedly when they are late coming home. He doesn't know if it's a malfunction or an emotion. Then, a sudden recall order for A-09 arrives from the developer. Ritsu is forced to choose, for the first time, to defy an order by his own will...
