The Lightning is Mine to Command!.
The story opens as Sayaka Kitaouji takes off from space and head towards Earth in her private shuttle where Todou briefs her on Uruyasu's stocks. On Earth, at St. Ignacio's School for Girls, two freshmen Saori Tachibana and Shihoko Sakaki head towards Orientation Day in the school's auditorium. Sayaka makes a powerful speech in order to receive more members for the already popular Debutante Club. Etiquette Club VP Rie Shibusawa tries her best to make a speech herself but ends up failing as president Reika Ayanokoji looks on in disbelief. The failed speech inspires Shihoko to join the Etiquette Club and brings Saori and their newfound friend Kanami Ezaki to the clubhouse. Once inside, arrows came flying out. Saori ducks under one, Kanami chops another in midair, but Shihoko was hit with the arrow. Luckily, it was a prop arrow. Reika and Rie explain everything about the Etiquette Club in detail to the new girls in hopes of improving their skills. At the end of the day, Sayaka heads off campus and informs Todou to take some men and rob the Mitsuido Bank, a bank that finances most of Uruyasu. Later that night, Saori, Shihoko and Kanami each sneak into the Etiquette Clubhouse and try to uncover its secret. They soon discover an underground base with Battle Skippers. Each of the girls pilot the Battle Skippers to where Reika and Rie are: the Mitsuido Bank. To the shock of Reika and Rie and even Todou's men, the new girls arrived and stopped the robbery. Todou decided to cut his losses and run, but his associates were soon captured by Reika and Rie and handed them over to the authorities. Back at base, Rie scolded Kanami, Saori and Shihoko for their reckless and foolish act, but Reika calmed her down and decided to welcome the girls as official members of Exters.
