The Adventures of Mini Goddess: Season 1

Gan-chan the rat is in need of a female companion. To help him, Urd arrives with a crystal ball and offers to predict Gan-chan's future spouse. However, Urd's predictions are all inanimate objects. She finally settles upon a kettle, and Gan-chan marries Mrs. Kettle. Urd gives the kettle a voice-over and legs during the honeymoon, but Gan-chan insists on Mrs. Kettle having her own voice. However, once Mrs. Kettle can speak, she declares that she has fallen for another kettle and elopes, leaving Gan-chan single again.

Gan-chan, Urd, and Skuld laze around because they are bored out of their minds. However, when a rat falls through the ceiling and mutters about a treasure before collapsing unconscious, they all become excited and decide to go treasure hunting. Skuld builds mechas for the entire gang, and they go to explore the attic. However, they get attacked by a large rat.

The gang does battle with the rat, but their attacks are largely ineffective in part due to the design of the mechas. They try to escape, but the rat calls in reinforcements and blocks their path. Gan-chan is volunteered to act as a distraction. A piece of cheese is strapped to his mecha and he manages to distract the rat gang. Urd and Skuld find the treasure, but it turns out to be a windup doll of a golden Buddha statue.

When Gan-chan expresses a wish to "fly like the birds", Skuld and Urd build him a series of progressively more complex flying machines, paralleling the history of flight. The devices begin with Urd's attempt to build Icarus' wings, followed by Skuld constructing the Montgolfier brothers' balloon, Otto Lilienthal's glider, Samuel Langley's (unsuccessful) Aerodrome and, ultimately, the Bell X-1, as Belldandy gives the history of flight. However, Gan-chan is still unsatisfied and wishes to travel to space.

Continuing on from the previous episode, Gan-chan is launched into space by Urd and Skuld in a Saturn-style rocket. He orbits around Earth before performing a moon landing, quoting Neil Armstrong's famous line. He plants a flag and takes a moon rock before returning to his ship. Urd and Skuld convince him to fly to deep space, but they leave him when Belldandy announces that dinner is ready, leaving Gan-chan alone in deep space.

After having gained large amounts of weight, Gan-chan is unable to fit into his hole in the wall. He begs Skuld and Urd to help him slim down. Skuld tries several inventions, including Mr. Sauna, Mr. Icy Bath, and Mr. 4000 Years, but they all fail. Urd gives Gan-chan a pill that causes him to exercise. He exercises furiously, and collapses exhausted after crossing the entire world. However, when everybody wakes up the next morning, they discover that Gan-chan ate like a pig following his exercise and regained his weight.

After eating a moldy cake, Gan-chan becomes ill. Urd and Skuld attempt to cure him using their potions and inventions, but to no avail. They try sprinkling salt, giving him exercise pills, silica gel, and a vacuum, but all to no avail. Finally, Urd seems to have solved the problem - only to discover that, as a side effect, Gan-chan has turned into mini-Godzilla named Gabira.

Gan-chan, in the form of Gabira, heads towards the kitchen. Urd multiples herself to form an army, and Urd and Skuld set up multiple lines of defense to defeat Gabira. Using toy tanks, they slow down Gabria, but fail to stop him. When the goddesses retreat to their final line of defense and play rock music, the mold is disgusted by Gan-chan's lack of rhythm when he attempts to dance. The stereo overloads however. Keiichi finally destroys Gabira by exposing him to sunlight.

The goddesses and Gan-chan find a can containing a vile-looking green slime which surprisingly tastes totally delicious. But the origin of this strange food comes as an even greater surprise - a mysterious vending machine which has appeared at the temple. Upon venturing inside, Skuld, Urd and Gan-chan surprise the operators, who eject them from the machine, transform it into a spaceship, and rapidly depart from the temple.

Gan-chan is having a bad day. Urd notices the ring Gan-chan has and asks Gan-chan if she can have it, and he gladly agrees. However, the bad luck almost immediately transfers to Urd, leading her to conclude that the diamond on the ring is cursed. They try to place a spiritual barrier on the ring, but it fails. The gang then attempts to exorcise the spirit in the ring, but a black cat emerges, gives them a business card, takes the ring, and leaves.

Gan-chan has a relapse transformation into the monstrous Gabira. Urd and Skuld, using the strategy that destroyed Gabira before, bathe him sunlight. Unfortunately, it makes Gabira even stronger. Skuld unleashes a golden mecha version of Gabria after having run out of ideas. They grapple, but then become friends, reconciling their differences and leaving the temple grounds.

Urd and Skuld argue about who is better at baseball. They duplicate themselves to make teams. Gan-chan and Belldandy commentate to a crowd of fake fans while the two battle. The game goes into extra innings, and Urd and Skuld begin to play in ridiculous fashions, like imitating the tornado pitch of the Tasmanian Devil. Urd then disappears for her "ultimate pitch," and the rest all imitate her, leaving the stadium deserted.

Urd babysits three little rats, named Ichiko, Jiro, and Juicy. When they all want to play different games, Urd replicates herself. When Urd makes an obedience pill, Juicy forces her to eat it, and it backfires. A thunderstorm arrives, to the terror of the young rats, but Urd reassures them. When they try to nap, Urd and Juicy snore so loudly that the other rats wake up. Finally, when it's time for Urd to leave, she promises to come back and play.

Gan-chan has fallen in love with Kaoru, a pink female rat, and has a date. He is extremely nervous, so Belldandy gives him a pill. Urd creates costumes for Gan-chan, who decides upon a collared bow tie and a red rose. Urd casts a spell on the rose so that Kaoru will love him forever. Gan-chan forgets the rose, however, and when Urd attempts to return it to him, he accidentally proposes to Urd instead of Kaoru, who leaves, devastated.

Urd and Gan-chan enjoy their newly wed life, that is until the magic rose petals start to fall down.

Urd goes on a trip on a rainy day.
