But the Ultimate Force that is linked to Keiichi's wish has other ideas.

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?

Marlier offers Sayoko a plan to get Belldandy out of the way. Sayoko tricks Urd and steals the Demons CD.

This is her big chance, but what are all these suggestions Keiichi has?

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 senpais, Skuld and Megumi enter a robot battle contest to settle their conflicts.

Skuld reveals her latest invention: Banpei-kun RX. Banpei is a robot designed to protect Belldandy, which he does easily as Marlier 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 Marlier launches another attack?
