"Exterminate! Exterminate!..." Thirty of Daleks are chasing to Doctor, Katie and Minami Yuuko. As they 'stole' Dalek's Spark Dolls, that found from the captured Yuuko, and Katie and Doctor are released her.

Doctor, "Can you use that Ace doll to transform now? Katie told me that you were being the human host of him!"

Yuuko, "I can't! The Ultra Rings are belongs to Hokuto now, without him, I cannot transform!"

Katie, "Careful, guys! The cliff!..."

Daleks let them be trapped on the dead end, and ready to kill them. Suddenly, Yuuko takes Doctor and Katie's hands, and says, "Keep holding! I'm ready to fly!" and they dash in the sky! Daleks chases them into sky, and launch the dead-laser messy. However, Doctor finds where's the TARDIS, that means they would escape success.

On that moment, one of the laser suddenly pass through three of them, and Katie is detach by Yuuko's loosed hand... but she flies and return to them, by herself.

She learns the first skill of Ultraman: fly! However doctor reminds Katie now is not the time to "hooray", but keeping her life and return to the safe place first.

They escape into the time tunnel at last.

Yuuko brings other Spark Dolls that she has and gives to Katie, they are Zoffy, Jack, and certainly, Ace. Katie use her Live Pad pen to touch each doll's left foot, and they all be collected into the pad safety.

Yuuko, "Well, I am not correct the location of Zero's base, since that is from alternative universe..."

Katie, "But TARDIS can."

Doctor, "Do you know what is the name of that base?"

Yuuko, "Mighty Base."

TARDIS arrives, and blinks into Mighty Base. Pigmon feels strange for this popping out blue box, and he yells by somebody comes out from it!

Glenfire comes out and says, "Why are you being too fuss? They are human, Zero said most of them are kind, just like you."

Katie asks that hot-temper alien, "Excuse me, sir. Do you know where is Ultraman Zero?"

"Who are you?"

"Higashi Katie! A Japanese-English, from Earth."

While Zero heard that girl's surname, he dash toward to her and ask more information: "Why you have Ultraman Taro's human host surname?" However, he also been asked, "You tell me why you haven't turn into Spark Doll first." and shows that Ultramans-including Live Pad.

So Zero replies, "Well, we are in the parallel universe, not many Ultras go through easily, even Dark Lugiel cannot finds us either. But how could you come here, Ace's lover?..."

Being quite awkward by that impolite call, Yuuko still answer him, "By that Time and Relative Dimension in Space, TRADIS."

"You are Time Lord!?" Mirror Knight being shocks to look at Yuuko.

Zero, "No, she is Alien Moon that immigrated to Pluto, she was being one of human host of Ultraman Ace, with Seiji... And loli Katie, are you a Time Lord?"

Katie starts introduce herself, she picks her Array to Zero's mouth, breezing with a sound like Sonic Screwdriver, "First at all, don't call me loli, please? Second, although I cannot turn my original Ultra form yet, but I, Katie, the future Ultragirl Maya will be, is the sister of Ultraman Taro, daughter of Father of Ultra and Mother of Ultra, and the student of that old Time Lord called..." she pats Doctor's shoulder, and he said, "Just call me Doctor."

"DOCTOR WHO?" Whole members of Ultimate Force Zero asks.

"By the way..." Zero feels strange, "How would someone like you to grip a dumbbell as like as grip a screwdriver? That's too heavy!"

From that day, Katie starts to learn many and many of fighting skills to UFZ, almost four mouths. Yuuko has return Pluto already. While on the resting day, she is learning some of knowledge of space and science. She refits her pink dumbbell with the power of Sonic Screwdriver, "at least I can protect myself stronger..." and her renames it into Sonic Array.

Doctor, "Katie, how weight of that? I mean, how could a girl can take this 5 kg..."

"Is 50 kg." And his eyes are nearby drops out...

"How could you..."

"Each muscles from Ultras is being stronger that human almost 10000%, you can try to take that." He takes that dumbbell and he feels hurts quickly ! Doctor returns to its master immediately, "Man, that's too terribly heavy..."

Sometimes, they would being quite silly and humor, like this...

Katie, "Eh, sorry? What are you talking for? Grill chicken?"

Jean-bot, "Sigh, that's a trouble nickname that Glenfire calls me..."

"Well... if Jean-bot is grill chicken, I think you must be a grill beef."

All guys are laugh by her humor, and Glenfire, the nickname maker, is feeling shy and awkward.

Mirror Knight, "What about me?"

"... Grill pork, the slim one."

Jean-nine, "And I won't is grill duck?"

Katie, "Duck cannot fly, so you're roast goose is better."

"And me?" Zero is the last one ask.

"..." she being silence, and pops out the answer in 30 seconds later, "grill goat? Because your double sluggers looks like a goat horn?"

All of them are feel joyful by that nicknames. "Just call Ultimate Barbecue Zero!" Zero said naughtily.

"Hum? You mean, there still have many of evil monster that have many plans to attacked Earth? I had fighted to Red King, Galberos, Belial... and more?" Zero makes a thinking face, and don't believe Doctor's adventures in the past.

Doctor, "Since they just attack into The Britain, just the monster who just attack to Japan, however they most of them in a similar size like human. Like Ood, Cyberman, The Slience, and... Katie, act the Weeping Angel."

And she places her hands into her face, hold stiil and doesn't move anymore.

Glenfire, "How horrible of that angel?" and he uses his finger to touches her head, still no more moves.

He turns back, and looks again...

...And suddenly Katie turns into a fierce, roar face, looks to UFZ! That horrible looks scare them and let them run away!

"Ha ha ha ha... Doctor is right, Weeping Angel is the most terrible monster in this universe..."

After learns that basic fighting skills, Katie thinks that's enough to take all of the Spark Doll back, even she still using a little Ultra Powers yet. Doctor finds in each Ultras arrived the Earth, they would met a girl also in white dress red shoes, like Katie. So he think maybe let Katie being the Red Shoe Girl is the key to get the Dolls back.

Zero, "Katie, even we cannot follow you yet, still we will check all of universe to make sure what the next plan of Valeyard or Dark Lugiel. So, leave peacefully!" He makes a high-fest to Katie, and she does.
