NR base, nine o'clock.
Kumon, the member of Night Rider aka the last Dunamist of Ultraman Nexus, receive the newest order. to defeat the Space Beast Frogos in the shopping centre, "They're reduce gradually after I killed Dark Zagi. Will the battle be finish in one day?" He ask this question, standing on the side of Captain Wakura.
"I don't know either. Maybe we having a next mission to defeat other evil alien? Now the concentration of The One's blue sparkles is less 5% that the original content in 2004..."
Here come Frogos, and blast with some of green fire-ball! Kumon fires and reply, "Still that's as hard as of past!" Nagi and Shiori show to civilian how to escape safely.
Meanwhile, TARDIS arrives that area, and ready to land, Doctor says,"Wow, another fight of monster and human is here, we have to move to another place..."
Maya looks closer to the screen that show what happened outside TARDIS, she yells surprisly, "Did I see wrong? Space Beast!? But the mastermind is died!"
"You mean that kaiju is just like Choju be control by someone?"
"Yes or no, he like to entice or control some kind of human to makes more Beast to attack that universe. Even that mastermind Dark Zagi is died, the elements of the origins to make Beast is still haven't completely be erase..."
BOOM!
One of the fireball hits TARDIS, damage her seriously! They are falling down... Doctor wanna use Sonic Screwdriver to fix her, but drops out of the broken window! And Katie? She still cannot using her dumbbell's function properly...
...At last, TARDIS drops on Frogos, crushed him to die!
NR arrives and research what is it, suddenly they are seeing two people come out on that blue box with kind of smoke... The elderly and a girl.
"I am the Doctor."
"And I..." she pats her dust of her dress, "Higashi Katie."
But this time, they suffer a kind of impolite treat, "Bring that old man and the girl into the base!" Wakura orders.
An hour later, Doctor and Katie have faced many of body check, interrogate, etc, they're being more and more impatient... Until one a member of Night Rider come and says, "You're the person that we've found, since your box is the only technology to inside a human body..."
Doctor, "If you just having a human body traveling, well, I won't."
"Is for saving a teenager's life!" Kumon answers emotional.
Therefore the first Deunamist - Shunichi Maki face to the Space Beast once again, even he cannot transform into Ultraman, however that power has possessed his only son, Tsugumu... Tsu-kun was had a great cancer, and NR couldn't find more plan to get inside his body to destroy Beast... They sure TARDIS is the last hope.
"Inside a human body is TARDIS never been, and why we have to help you?"
"Doctor!" Katie says, "To help the human host is the only way to let us get it own spark doll..."
"No no no, I'm not being neglected... I just worried does she efforts or not."
TARDIS arrives Tsu-kun's spleen, and the fighter are standby for protecting the blue box.
Nagi, "Space Beast invade the teen's lymphatic system and makes his immune system poorly out of control. Being his was get blood cancer, his percentage of white blood cell decline suddenly..."
Kumon takes the Evoltruster, and Nagi chase with him. Doctor amused that won't they be discover their identity of Nexus? "That'e every knows that already, but had been cruel to treat those Dunamists since TRT wants their power to improve themselves... but NOT now." Nagi answer, "Even me also was misunderstand Nexus... also is Space Beast."
Suddenly lots, lots of blue dusk inside that teenage's body, are merge together, one of that also crash TARDIS! So is DARK LUCIFER, another dark giant that Dark Zagi's secret servant. After Zagi=Ishibori Mitsuhiko be killed by Noa=Kumon, he was waiting chances. Now he finds the son of the 1st Duramist, who had a cancer at once, to be his own cave, making Shunichi feels grief!
"How can make it out of this boy's body?"
"Lead DARK LUCIFER into TARDIS, however she..."
"SHE?"
"Don't chip it! She is broken and I need to go inside fix it. Katie, you stay here helping Night Rider."
"Roger."
When Doctor go inside the heart of TARDIS, Kumon transforms into Nexus, flies outside the blue box! And Riders follows him. They start shoot on DARK LUCIFER makes him attack them, then they 'escape' into the blue box once again, on that other hand, Maya scales TARDIS bigger for fitting these giant's height. "Another step is... Maya Shield!" She makes a crystal-column-like glasses covers to the console to protect 'Miss TARDIS' and Doctor. They came at last.
Wakura, "Katie, we can leave now!" She press the button, and they go outside onto... the nearby ground. Later, Nexus opens his Meta Field to let all of them drop inside, not let the city and its citizens get hurt.
However... Doctor gets outside the heart with worried face, "She using lots of power to let us go outside, makes her injuries getting worse... unless she gets her own healing power like my regeneration, she'll died in 15 minutes."
"Doctor, why don't you use that?"
"I'll use up mine! By chance I died on future, no one can stay with you finding all Ultra Spark Doll!"
Katie thinks a second, and she tap her right hand to her left wrist, yells "Maya Healing Beam" and put right hand on front, right hand runs out lots of pink light get inside the heart of TARDIS to repair now. Her faces showing she's toilful cause she's using own energy to cure the time machine.
Finally, Nexus using finisher - Over Ray Storm defeat Lucifer successfully, and Katie's fixing is done. Don't know does TARDIS absorb too much energy that she can afford, she spits the yellow-fog-like light ball! It bounces inside, and finally... Katie hit by the ball and, inside her body!? After a yell, she faints.
Doctor finds the Ultraman Noa doll appears on Katie's hand, he replaces her to scan that doll. "Ultraman Next! Ultraman Nexus! Ultraman Noa!" And he opens the TARDIS to leave.
He looks worried to the fainted girl, and checking her body with his Screwdriver. However, on her chest, he finds a double beating... One part of herlarge vein is morphing a new organ: another heart.
"No... Do her change into a time lord now?"
Looking TARDIS leaves, Kumon says, "Except Ultraman, Space Beast, even Time Lord, this universe still have lots of different biological lives. Whoever the're good or evil, individual behavior on one does not mean that its race are. We have to find the overall, not made a wrong like European was done on New World."
