Concept Heroine

The fruit of Satou and Yamazaki's pilgrimage to the holy land. She's your childhood friend / classmate / next door neighbor! But the thing is, she's a robot, and not only that—she's also a maid! What's more, she was the main character's girlfriend in his previous life! On top of that, she's very sickly and the main character is the only person she can rely on! Then she sacrifices herself in order to save him in a car accident, and suffers injuries that require a whole year to fully recover from! But the truth is that she's a ghost! Not only that, she's an alien! But her real identity turns out to be the reincarnation of a fox from space!
