Synopsis
A year after a spaceship carrying alien refugees called "DearS" crash lands in Japan, the government integrates them into society through a homestay program.
Takeya Ikuhara, a high schooler who dislikes the DearS, unexpectedly encounters Ren, a DearS who imprints on him as her master after he saves her.
Now, Takeya's life is turned upside down as he navigates the unexpected arrival of Ren, who is devoted to serving him, and grapples with the implications of having a DearS living with him.
