Episode 1: Virgin Flash 

A young tech (Yumi Francois) out delivering plans realizes she is lost, and 
accidently stumbles into an unknown office.  Inside, a strange figure in 
dark glasses sits.  She apologizes for interrupting and leaves, wondering 
who the strange man is.

On the fringe of our solar system, the United Earth Fleet tried to stop 
Radam’s advance, but they are unsuccessful because their special Sol 
Tekkamen strike-force has not arrived yet.  Even with the Sol’s help, the 
officers realize it’s only a temporary measure, and what they really need 
are true Tekkamen.

On earth the Tekka-cadets keep practicing, while Yumi stands by and watches 
them.  Once practice ends, Yumi is chastised by Natasha for not having 
fixed a communication pack.  Natasha says that her mistake could cost the 
life of one of them.  Honda steps in and takes the blame.  As Natasha lets 
Yumi go, she sees the crystal revealing that Yumi is also a candidate for 
the Tekka-process.

Later, Yumi pretends to be a Tekkanman and is surprised by the young pilot, 
Hayato.  They sit down to talk, and both wonder who the third Tekkaman will 
be.  Aki shows up and tells Hayato to take Yumi up in the Gamma for a 
tryout.

All team members are present when Aki announces that Yumi will be the third 
Tekkaman.  Everyone is surprised, and Natasha demands to know why Yumi was 
chosen.  Aki says, if she has a problem-she can leave.  Aki also informs 
them about the special weapon "Reactor Voltekka."  This will enhance the 
power of a Voltekka, and cause the intended target to be encompassed by a 
crystal field, becoming an additional voltekka; which will then spread in 
different directions, causing further objects to be engulfed, and so on... 
But it can only be attached to one person, and Natasha is chosen to wear it.

The Tekka-cadets go to the Tekkplant for the procedure which will take 10 
hours to complete.  Aki hops that they have 10 hours before Radam attacks.

Out in space, the United Forces are decimated by an alien Tekkaman.  It 
wipes out the squad of Sol Tekkamen and then destroys the flagship with its 
Voltekka.  The Radam then opens a multi-dimensional wormhole and sends its 
missiles to their designated targets.  This causes a disruption in the 
tekka-process.  When Aki, David and Natasha regain consciousness, Aki tells 
them that the process is only 90% complete, and due to a computer error, 
Yumi was given the Reactor Voltekka.  The Radam have destroyed the fleet 
and warped into earth’s orbit, so the Space Knights must fight...

In space, Aki orders the attack, but holds Yumi back because she’s 
untrained.  David and Natasha transform and go after Radam, using their 
Voltekkas on the alien Tekkaman, but only destroy his hovercraft.  It 
counterattacks and is crushing both of them in its grip, when Yumi disobeys 
Aki and tries to save them.  But unfortunately, Yumi can’t fight.  
Realizing that she can use the Reactor Voltekka, she activates it, 
instantly destroying the alien Tekkaman and enveloping the entire Radam 
fleet.  Being a rookie, however, Yumi can’t stop the reaction and it 
continues to grow, affecting the Orbital Ring.  Aki quickly stuns Yumi with 
a laser shot to break her mental control of the Reactor Voltekka, which 
then dissipates.

Back on earth, Yumi is confined to quarters for insubordination and 
destroying part of the Orbital Ring.  She protests, but is slapped by 
Natasha, who tells her she is totally unqualified to be a Tekkaman.  Yumi 
sits and cries in her quarters as Natasha’s words echo - while D-Boy senses 
the approach of the Radam fleet’s second wave.
