My Merry May

Kyosuke is a high school student who lives a normal student's life in a dormitory until one day he receives a strange device from abroad. Inside the device is a female replis, an artificial human being.

Kyosuke decides to awaken her, but before her personality is fully loaded, a thunderstorm briefly cuts the energy in the dormitory, creating a bug in Leu's system. Instead of his own personal servant, Kyosuke now has to take care of a teenager with a childlike mind.
