DearS

The "DearS" program was established after a UFO carrying 150 aliens crash-landed off the Japanese coast. To integrate them into society, the government taught them Japanese language, customs, and culture, and created a home-stay program to facilitate human interactions. Ren, one of these aliens, was released from her capsule by a truck accident and found by high school student Takeya Ikuhara. After being named Ren, she became imprinted on Takeya as her "Master" and "Slave," choosing to remain with him.
