Synopsis
Impure alien (human) exchange has begun !? Living with a moon rabbit that started when it collided with a UFO!

What is YOU going to the moon? ――When I was hit by a UFO, it was on the moon.

Apparently, it was an alien named Teruya, the first princess of the "Moon People" who kidnapped me. The wild princess was a "beautiful girl in a rabbit".

Chikyuu Love's Teruya is cute, but somehow out of place ... In order to escape from the marriage of convenience, she says to become a fake couple and live together on the moon. Moreover, if it is a lie, it seems to be the death penalty ... What kind of coercive force is amazing. It's beyond the realm of cross-cultural exchange !? I'm slapstick with the Queen (cold) and Teruya's son-in-law candidate (superhuman) on the stage of "the city of the moon" like Heiankyo ... What happens to me !?
