ビリーヴ・マシーン 外伝
A young genius creates a sentient sex bot, but his overzealous efforts result in an artificial person with emotions and desires. He falls in love with her, yet doubts linger. To test her ability to form genuine human bonds, a second prototype, Unit #2, is given temporary free will and dropped into the world without memories or instructions, unaware of her origins as a sex bot. She believes she is a general-purpose household product.
Left lying in the street, Unit #2 is rescued and grudgingly taken in by Masaru, a college student disillusioned and distrustful of women. She vows to forever remain by his side. This is a tender love story exploring the powerful bond that develops between the young bachelor and the robot he calls Yuu.
