Ah! My Goddess

Keiichi takes Belldandy to his school, and all the classmates are impressed by the new girl. Sayoko, the popular girl on campus, meets Belldandy and tries to figure out where she came from.

Keiichi left his books and papers at home, so Belldandy goes back to get it. As Keiichi is left alone at school, Sayoko challenges him to stop acting like he's in elementary school with that relationship. Keiichi struggles on what to say to Belldandy. He sets up a romantic mood at home with candles and all. Will that do the trick? Or will it be written off as another coincidence?

A young woman shows up at the temple where Keiichi is staying. It turns out to be Keiichi's sister Megumi, who is in town looking for apartment housing. Keiichi and Belldandy help Megumi find a place, but it has a dark secret.

Belldandy learns about Valentine's day in Japan. Sayoko tries to set Belldandy up with the campus playboy Toshiyuki Aoshima. This could be trouble!

Keiichi gets a video from a store, but when he plays it, a mysterious woman shows on the screen. The woman is Urd, who is Belldandy's older sister. Urd tries to move Keiichi's romantic intentions forward by slipping him a controlling love potion.

Belldandy wins the Miss NIT contest and becomes Campus Queen. Sayoko and Toshiyuki try to uncover Belldandy's identity by setting up revealing situations where Belldandy would have to use her magic, but with big sister Urd watching, that isn't so easily done.

The Nekomi Motor Club is recruiting new members, but now there's a new rival club called Four Wheels that was started by Toshiyuki. The motor clubs have a challenge race over who gets to keep their club around.

Marller offers Sayoko a plan to get Belldandy out of the way. Sayoko tricks Urd and steals the Demons CD. Marller casts a spell to tip Keiichi's heart balance so that Keiichi becomes fixated on Sayoko. After Belldandy goes home feeling strange, Sayoko is alone with Keiichi. This is her big chance, but what are all these suggestions Keiichi has?

When Heaven's main computer, Yggdrassil, crashes due to an infestation of "bugs," a lone Goddess determines that she needs the help of her big sister... Belldandy!

Skuld's been spending a lot of time with Belldandy, but Belldandy still wants to go to school with Keiichi. Skuld decides to take apart Keiichi's bike, but ends up upgrading it. Megumi notices the upgrades and starts to critique it. This upsets Skuld, who issues Megumi a mechanic's challenge. At the suggestion of Keiichi's senpai, Skuld and Megumi enter a robot battle contest to settle their conflicts.

Skuld reveals her latest invention: Banpei RX. Banpei is a robot designed to protect Belldandy, which he does easily as Marller shows up for an attack. But that also means protecting her from Keiichi and Urd and draining tons of power from the house. Can Skuld teach Banpei to play nice? And what will they do when Marller launches another attack?

Marller's attacks on the goddesses keep failing so she goes for a new target: Megumi! She takes over Megumi's body, and solicits the help of Senbee, the God of Poverty and generally bad luck spirit.

Megumi gives Keiichi some tickets to a beach resort. Keiichi and Belldandy go, but the sisters tag along as well. Urd tells Keiichi there's an island spot where if he confesses it will be true love. Keiichi tries to take Belldandy to that remote island location, but Skuld has other plans.

Urd makes a love candy for Keiichi, but Skuld suspects something and slips in some additional ingredients. Belldandy consumes it, and she becomes very romantically bold in all her actions and with Keiichi too!

Urd and Skuld leave to do some work back at heaven. Skuld has Keiichi eat some flan which transforms Keiichi into a woman. Now he'll keep his hands off Belldandy, right?

Skuld admires Belldandy's angel and wants to have one as well. Skuld tries training her skills with inventions. Then something outside threatens the girls and it's up to Urd to summon her angel, but it's revealed that Urd can't because she told her angel earlier to never come out ever again. What will the goddesses do?

Marller retrieves a demonic urn from a cave. Urd's goddess license had been suspended, which motivates her to look for a regular job. But when things go bad there she accepts her demonic heritage and transforms into the Lord of Terror! Big trouble for Keiichi and the gals!

The Yggdrasil system is in chaos from all the attacks from the Lord of Terror. Urd starts releasing the Ultimate Destruction Program which will not only destroy the current world but allow the demons to rule it. Belldandy decides to release her sealed power and confront Urd. God gives Skuld a Midgard Flute as a last-chance vaccine to stop the Lord of Terror. Will those efforts be enough?

It's the final showdown where the goddesses, Belldandy and Skuld, battle against the Lord of Terror, who has now possessed Midgard! With the whole world at stake, what can Keiichi do to help?
