"I wanted to see you” are the words Kasugai Tenka wants to hear from a girl more than anything. And when the high school student hears it from Tsukimi, a girl literally out of this world, his life is about to get crazy. Tsukimi was a war general on the Moon, but she was exiled for the destruction she caused and her memory is wiped clean and she's changed into a bunny. She reminds Tenka that years ago, he fed her soba from his dad’s soba shop and that now that she's gained human form and her powers back, she wants him to be hers.
