In the Planet Of Nebula M78 known as the home of the Ultras and the Land of Light.

We see Father of Ultra and Mother of Ultra watching something on the Holographic Monitor.

Mother of Ultra saw the Idol of B Komachi Ai Hoshino was stabbed by the stalker.

Mother of Ultra: Oh no!

Mother of Ultra heard Ai's words.

Ai: Aqua....Ruby I love you both....

As she dies infront of them Mother of Ultra was touched by her words.

As she walks away.

Father of Ultra: Marie where you going?

Mother of Ultra: I want to talk to Ultraman King about what I'm going to do.

She talked to him about she going to do. Knowing a Kaiju would appear on earth.

Ultraman King: I see.....is that what you want Marie?

Mother of Ultra: Yes......I was touched by her words and she could be the perfect Human Host if we become one.

Ultraman King: Ok I will allow you to on earth and do everything you can.

She nodded as she saw Father of Ultra and Taro.

Taro: Mother are sure about this?

Mother of Ultra: Yes.

Father of Ultra: Be careful Marie.

Mother of Ultra: I will.....

She flys away from the land of light as she pursue herself to earth.

We saw Ai Hoshino's dead body in the hospital bed when a sun came and appeared before her.

Mother of Ultra appeared before her.

Mother of Ultra: Ai Hoshino.... Seeing yourself being killed by the killer and telling your children you loved them really touched me. Similar to you how I loved my son Taro.

Suddenly a Manifestation shows Ai Hoshino was killed by a Stalker and another Manifestation shows Mother of Ultra fighting a Giant Kaiju.

Mother of Ultra: I can't stay here with no physical form Ai that's why I shall grant you my life and become one with you. Let's fight together and bring happiness to people and protect the humanity here on earth. And also I will give you this.

She summoned a Necklace called Ultra Heart Necklace that is attached around her neck and the blue heart gem on her chest.

Mother of Ultra: The Ultra Heart Necklace gives you willpower to activate and you will receive great power from me. Now I shall merge inside your body as we become one.

Ai's body suddenly floats in the room as Mother of Ultra merges inside her body becoming one with her.

Ai's stab wound on her stomach is fully healed after her merging with Mother of Ultra as her body flashes with light. As everything turned back to normal.

Ai suddenly woke up.

Ai: Huh? What happened to me? She looked at her stomach that it was fully healed.

The nurse entered and she was shocked Ai is alive.

Her Idol Agency also knows that she is alive again miraculously.

No one knows that Mother of Ultra merges with her.

Her Children Aqua and Ruby saw her mother alive again and hugged her.

She went back home to her same apartment with her kids. While seeing Aqua and Ruby playing with each other she notices her Ultra Heart Necklace around her as she looked at the Moon that is illuminated with Mother of Ultra.

She went outside from her balcony seeing mother of Ultra from the moon from an illusion.

Mother of Ultra: Ai Hoshino......

Ai: Who are you?

Mother of Ultra: I am Mother of Ultra.

Ai: Mother of Ultra?

Mother of Ultra: Yes.... remember you died once..... because of a mad fan....I revived you back to life.

Ai: How did you revived me? And also where you came from?

Mother of Ultra: I'm a Alien from the planet called Nebula M78 known as the land of light.

Ai: Land of Light?

Mother of Ultra: Yes I'm a intergalactic defense force that protects giant kaiju from earth attacking the city. I was also a silver cross aid that a medical relief unit for intergalactic defense force. I came here on earth to stop the evil forces that is attacking the city.

Ai: But why did you came to me?

Mother of Ultra: I see how your kids love you....and seeing how your fans loved you and I found you as my human host. Because I can't fight with no physical form on earth.

Ai: The reason why you gave me this necklace?

Mother of Ultra: Yes Even though you an Idol you still have the responsibility to be a Ultraman. That's why you'll be called "Ultra Mother".

Ai: Ultra Mother?

Mother of Ultra: Yes Ultra Mother....we share the same love to our children together.

Ai: Who is your relatives in the Land of Light.

Mother of Ultra: Father of Ultra who is my husband Taro is my son together with his Ultra brothers the first Ultraman, Zoffy, Seven, Jack and Ace.

Ai: Them?

Mother of Ultra: Yes......mostly all of them has human hosts just like you.

Suddenly she heard an explosion in the city.

A Kaiju named Astromons is attacking the city.

Mother of Ultra: Ai it's time.

Ai: Me?....

Mother of Ultra: Yes let your children play together in here.

Ruby saw her mom going out.

Ruby: Mom where are you going?

Ai: I'm going to check something outside you two stay here.

She went outside on her apartment she closed her eyes as she tries to get her willpower then the Ultra Heart Necklace shines with light as she rises up transformed as a giant transform I into Ultra Mother.

Ultra Mother jumps and flies her way against Astromons and kicks him in the head.

Ultra Mother fighting Astromons as she uses her punches on by punching it's inmer chest.

She uses her Mother Kick striking it's head. She then grabs him and throws Astromons on the other side.

But Astromons fought back as he sprayed Ultra Mother with his mist. Making Ultra Mother unable to fight. Astromons striking Ultra Mother with his long arms.

This causes Ultra Mother make her light bulb on her chest started bliping in color red knowing she is running out of power. 

She stands up and defend the attack against her.

Ultra Mother: Haaa!

She throws Astromons on the other building.

As Ultra Mother performs her finisher.

Ultra Mother: Mazā Hakai Kōsen!

She shot Astromons with one shot hit destroying the Giant Kaiju.

As Ultra Mother's lightbulb bliping in red in her chest she flies away from the city as she came back from Ai's apartment.

Ultra Mother transformed back into her human size and back into her human host as Ai Hoshino.

Mother of Ultra: See Ai there's nothing to fear of.....

Ai: It's my first time transforming into a Ultraman.....

Mother of Ultra: Yes....but now go take a rest your children are waiting for you.

She came back to her apartment as she spent her time bonding with Ruby and Aqua.
