Plot:
At the Galaxy Police space station, the first class prisoner, Kain, escapes from his cell and travels into the past. The station
explodes. Kiyone and Mihoshi are in near Earth and get a message about the destruction of the space station when something
hits the Earth.

Suddenly, Tenchi starts fading out of existence.
Cutting back to 1970, Mihoshi is a teacher. Kiyone is a janitor. Ryoko and Ayeka are students in class with Tenchi’s
parents. Back to the present, Tenchi, Ayeka, and Ryoko are watching a home movie his dad made of mom. Atchika, Tenchi’s
mom, starts fading out of the film. Tenchi starts fading out of existence again when Washu is able to save him. Apparently, 26
years ago, Atchika disappeared. To insure the continued existence of the universe, they must keep Atchika from being erased
from existence. They’ll have to go back in time to protect her.
Washu sends them back in time and warns Tenchi not to meet his mother. Back in the past, Ayeka and Ryoko are
fighting.

Your money or your life...
In PE, Tenchi watches his mother from afar.
Later, that day, Atchika goes home and finds Ayeka and Ryoko there. The girls live so far off they needed a closer place
to school. Suddenly, teacher Mihoshi stops by.
In the present, Washu has realized that Atchika will be killed within 7 days.
The next day, the brooding class guy keeps watching Atchika to the point Ryoko starts thinking he’s suspicious. Atchika
notices Noboyuki’s drawings and they talk about architecture. The class is going on a field trip to Tokyo Tower.
Washu brings Kiyone back to the present. She realizes the destruction of the Galaxy Police headquarters has the same
energy pattern as Atchika’s disappearance which means that Kain is tied into it. If so, he will appear in Tokyo to eliminate
Atchika.
In the past, the class is getting ready for their trip. Nobuyuki takes a short home movie of Atchika (the one Tenchi was
watching in the beginning). Ayeka and Ryoko are teasing Atchika and Nobuyuki. Ryoko notices the brooding guy and starts
to chase but loses him. She eventually catches up with and learns he’s actually a Galaxy Police officer following Kain who
is trying to eliminate the House of Jurai descendents.
Kain is heading into the past. Washu sends a message back that Kain will strike at Tokyo Tower. They don’t have
anyone who can direct energy to stop Kain. Washu has some equipment that can be placed around Tokyo which will
imprison Kain.
Tenchi heads to place the transmitter at Tokyo Tower. Ayeka, Ryoko, Sasami, and the rest place the transmitters
around Tokyo and head to the tower. Atchika and Nobuyuki are with their class at the tower.

Zeram, eat your heart out...
As Kain materializes, the Galaxy Police officer attacks him but is promptly killed. Tenchi is setting up the transmitter
up as Kain reaches the tower. He sends Noboyuki to activate the transmitter as Tenchi defends Atchika. However, Kain
gets the upper hand when Atchika starts to power up. Noboyuki starts the transmitter which starts to suck Kain into the
Phantom Zone or Negative Zone, or subspace. Atchika and Noboyuki are trapped with Kain.
In subspace, Noboyuki finds Atchika.
Washu has a long shot plan that might work to send Ayeka, Tenchi, and Ryoko to face Kain. The dangerous part
requires using the Dimensional Cannon.
Ayeka, Ryoko, and Tenchi are beamed into subspace. Kiyone preps the Dimensional Cannon.
Subspace, Atchika armors up to attack Kain when the cavalry arrives.

Samurai Geisha Girl just didn't draw the audiences that the creators
expected.
Tenchi wields his lightsaber at Kain who morphs into a giant monster that knocks him out.

What is this Schwartz you keep talking about?
Atchika grabs the energy sword and carves Kain like a turkey. As
they head for the portal, Kain is reforming and following after them. The Dimensional Cannon hits Kain and traps him
in subspace as the others make it to Earth.
Before Ayeka and Ryoko head back to the present, Atchika asks them to watch Tenchi. Ayeka erases Atchika’s
memories of Kain, etc…Ayeka, Ryoko, and the unconscious Tenchi sent back to the present.
Tenchi narrates how Atchika wielding the Jurai power shortened her life. In the past, Noboyuki and Atchika are
married and have a baby. Atchika’s father suggests Tenchi.
