Enjoy the sweet newly-wed and "childmaking" life with this game brought to you by Norn! In this game, you're married to a big-sister-like goddess and your goal is to have some kids!

The main character, Kazuhito, is an ordinary yet kind ronin (student trying to pass college exams).

One day, while stargazing, he spots 3 goddess sisters as the ascend to Earth!

Kazuhito, who heard that if a goddess' identity is revealed to a human, they will be sealed to that human, decides to protect the 3.

Even when an angel comes for judgment, Kazuhito lies and says there is no problem, as he is engaged to the loveable goddess Flora.

The angel demands that they bear a child as proof, which was the beginning of Kazuhito's fun and sweet newly-wed life with a goddess!
