Ep1. Can't Buy A Thrill

Mega City TOKYO, 2040.
"Boomer's" which are generalized androids with live organ functions rapidly reconstructed the capital that suffered massive damage from a huge earthquake 7 years ago. However, on the flip side, they can also suddenly go insane. These Boomers are called "Mad" Boomers in such an unstable condition and will initiate subversive activities. Mad Boomer cases are becoming more frequent and more severe. Even the special "A.D. Police" force has trouble dealing with the increasing number of Mad Boomers. There is a mysterious group who has thrown down the gauntlet against the Mad Boomers. They have high spec powered armor hard suits, and seem to appear from nowhere. They are the "Knight Sabers" a group of young women who live out their secret lives in mega city.

The super conglomerate "Genom" dominates the development and sales of the "Boomers" market with their original Voomer brand. Genom cooperation's affiliate company, Hugh Geit, has a new employee, Office Lady (OL) Yamazaki Linna. She is almost hit by a female motorcycle rider on her first day of work. Startled, she tripped and dropped the lunch she just bought. On top of that, she scraped her forehead. Furious at the female bike rider, she chases her but just misses catching her. Later that day, her manager, Ken, asks her out, offering to show her around Tokyo. That night, with Ken, she sees a female singer, Priss Asagiri's poster and recognized that Priss is the female biker who startled her in that afternoon.

Linna and Ken walk around the streets and have dinner in a Bar. Linna is about to go home because it's late, but Ken stops her and asks her for "closer relationship" using the fact that he is the human resource appraiser as leverage. Linna, angered by his attitude, is about to leave when a mad boomer suddenly breaks into the bar. Ken selfishly runs away by himself leaving Linna behind. Linna finds another exit on the other side of the Bar and tries to escape by the emergency staircase. But the Mad Boomer chases after her and destroys the stairs in front of her. Because of the sudden attack, Linna is hanging over the street in great danger. A Blue hard suit suddenly shows up in front of Linna and saves her live. Linna stares at the blue hard suit and whispers comprehendingly "Knight Sabers". The blue knight saber used the same motion to show Linna her scrape on her forehead just like the female biker did earlier that day. Linna realized the Blue Knight Saber is Priss. Priss destroys the Mad Boomer with the superior force of her hardsuit. Linna is stunned by the power of Knight sabers and falls down from the stairs. But the other Knight Saber, Nene Romanova saves her.
Next day, Linna gives Ken a right hook to the jaw to thank him for the previous night. Later that day, Linna shows up at the Live House "Hot Legs" and waits for Priss in the back alley. She tells Priss her about her long time dream, "I want to be knight saber too." But Priss makes no indication as to the accuracy of her revelation and drives away leaving Linna standing there alone.

Episode 2 "Fragile"

A.D Police Frontline Officer Leon McNichol and Daley Wong are aggravated by the unclear and slow acting head quarters while the Knight Sabers are stealing their thunder. About the same time, Linna is wondering why the media does not report the Mad Boomer case she encountered last night. She uses her company computer to hack the AD police's server for more information, but Nene, who works as an operator there, blocks the information and stops Linna from hacking. That night, Linna stops by Priss's live house and tries to invite herself into the Knight Sabers again. Priss doesn't take her seriously and drives away, but Linna doesn't give up so easily this time, she follows on her scooter as fast as she can. Finally she finds Priss with an unknown woman in front of the Silky Doll boutique. Linna enters the boutique as if invited and finds a secret elevator hidden behind the fitting room mirror. When the elevator door opens, she finds Priss, Nene and the unknown woman, Sylia Stingray, waiting for her. The boutique houses the secret base of the Knight Sabers. Linna again states her desire to become a Knight Saber. Sylia, the leader, smiles at Linna approvingly and suggests that Linna experience a simulated battle from the action recorder. Linna is shocked to learn that the battle is more strenuous than she had originally anticipated.
