Dreaming of meeting a destined man, Mahiru, a single female programmer with glasses who is plain and dull and shy, gets the ability to transform into a beautiful woman due to a mistake by the god of death . Her two conditions are that she can transform only at night when there is no sun, and that if someone finds out about her, that's the end of it. She fearfully ventures out into the night town, which she had shied away from until now, and immediately becomes the target of men's desires... Beyond the dazzling pleasure and frenzy, can Mahiru really find her true "love"!?
