Daily Life with Monster Girl is a story about Kurusu Kimihito and the lamia he is hosting, a girl named Miia. Three years ago, the government revealed the existence of monsters to the world and began working to integrate the two societies. Just like human cultural exchange programs, some humans have been sent to live with monsters, while some monsters are now living with humans. Due to an error, Miia ended up at Kimihito's house by mistake, but her case worker is too lazy to fix it. Over time, Miia ended up falling for Kimihito, but due to the laws governing the cultural exchange program, if they ever consummate their relationship, she'll be sent back to her own country.
