Keiichi Morisato, a college student and member of the Nekomi Institute of Technology Motor Club, lives a relatively ordinary life until a chance encounter changes everything. One evening, while attempting to order food, Keiichi accidentally dials the Goddess Help Line, a celestial hotline that grants wishes. Belldandy, a kind and serene first-class goddess, appears before him and offers to grant one wish. Overwhelmed, Keiichi jokingly wishes for a goddess like her to stay by his side forever. Belldandy takes his wish seriously, and from that moment on, she becomes a permanent presence in his life, moving into his dormitory and bringing a touch of the divine into his mundane existence.

As the story progresses, Keiichi and Belldandy’s relationship deepens, evolving from a simple wish fulfillment to a genuine bond of love and mutual respect. Their connection is tested by various challenges, including the arrival of Belldandy’s sisters, Urd and Skuld, who bring their own unique personalities and complications. Urd, a second-class goddess with a mischievous and seductive demeanor, often stirs up trouble with her potions and schemes, while Skuld, a third-class goddess and a brilliant inventor, is more reserved and prone to jealousy. Together, the three goddesses form a dynamic trio that influences Keiichi’s life in unexpected ways.
