Chapter one updated! I just had to rewrote some part to make it have more sense. Chapter 2 will come soon.

Somewhere in Gamindustri, at the border between the land of Planeptune and Lastation, two familiar girls were walking, one with lilac-colored hair and 2 D-pad clips, and one with raven-colored hair tied up into pigtails with ribbons. It was the 2 countries' CPUs, Neptune and Noire. They were looking for something.

"Neptune, are you sure that it's here?" Noire asked with her arms crossed.

"Sure do. The quest marker said that it's here." Neptune answered.

"Why did you call me anyway? Can't you call Nepgear to go with you?"

"She totally wanted to hold onto my hand all the way, but she was going to hang out with Uni already, so I told her that I'll ask someone else to help me out, so she can enjoy her one-on-one time with your sis." She winked meaningfully.

"So that's why Uni was preparing herself today… What are we looking for anyway?" Noire then asked to the point.

"A monster!" Neptune answered excitedly.

"What?" Noire was confused.

"But it's not any run of the mill monster. The quest was an S-rank one and it said the monster is really bulky and strong. I can still totally deal with it myself, but I called you over just to make sure, in case I need some bait. Aaaand the monster is located between those two landmarks." She pointed just ahead of them.

"If you are defeated then don't call me out for help then."

"AHHHHHHHHHHHH" A yelling was heard.

The two girls stopped and looked around them.

"Wait... This feeling..." Noire realized something.

Then she looked up.

A girl fell onto her.

"Ahh... That was quite a painful landing. At least I've landed on something soft..." The girl looked at who she was sitting on. Noire faceplanted onto the ground, her hand was twitching.

"Nepu! A wild girl fell from the sky!" Neptune pointed at the girl.

"Ah! I'm sorry Oka...Noire-san! Are you ok?" She quickly got up and helped Noire.

"Why am I always the landing cuision for falling people...?"

"Are you some kind of alien that tries to take over Gamindustri?" Neptune said, then looked closer to the girl's outfit."You are totally copying our my style too! Are you going to kill us and then take our place?!"

"Let just say that I'm your biggest fan. And don't worry, I'm not planning to take over Gamindutri. It's belong to you CPUs after all."

"Hmm... So you are my fan, huh? Do you belong in that fanclub of mine?"

"What is your name then?"

"Call me Terra."

"Alright then, Terra. Now we need you to go back to your home. We are going to fight a pretty big monster here."

"Home, huh...?" Terra showed a hint of sadness in her eyes.

"Terra, what's wrong?"

"Nothing. I'll be going now."

Then she walked away. Or did she?

She followed them from behind, hiding behind trees as she went.

Then a roar was heard. They quickly ran to the source of the sound.

"Now then, let's see who can defeat the monster first then." Noire suggested and then transformed.

"Game on!" Neptune followed and transformed as well.

They flew to the place and saw a giant monster. It had a humanoid figure, and its arms were big. It has blue-colored armor around its body and was three times as tall as Purple Heart.

"I didn't expect it to be this big, but let's not waste anymore time!" Purple Heart said as she dashed into battle.

But the monster was proven too strong for them. It looked big but was very nimble. Every attack they tried to land on the monster, it either dodge or parry it then land a hit on them. They couldn't even scratch the monster.

"What kind of monster is this? We have never seen one like this!" Purple Heart said, breathing heavily.

"It's really similar to the "delusional monster" we have once fought before, but the same time it's not."

Suddenly, the monster appeared behind Black Heart and attemped to land a hit on her. Black Heart didn't notice, but Purple Heart quickly reacted by pushing Black Heart to the side, raising her katana trying to block the hit but it failed. The sword broke and the monster landed a direct hit onto Purple Heart. She was flung away and landed onto the ground, untransformed.

"Neptune!" Black Heart yelled.

Then, the monster attemped to hit Black Heart next.

"Hyaaaaaaaaaaah!"

A similar voice was heard.

"Huh?" Black Heart looked and saw a girl apparently fall from the sky kicked the monster in the face. It stumbled back a bit, but quickly regained its stand.

"Are you ok, Noire-san?" The girl asked Noire.

"Hu-Huh? Yeah I'm fine…Why are you still here? I though we had told you to go back!"

"That's not important right now. Please take Neptune-san and get out of here! Leave the rest to me."

"I can't do that! That monster is too strong! We CPU can't even do anything to it, let alone you!"

"Just take Neptune-san to a safe place, and watch me."

Black Heart didn't understand what she was trying to do, but quickly put Neptune to a safe place.

"I didn't expect you have already spreaded at this point in time, but here we go!" The girl said.

She pulled the right side of her jacket aside, revealing a container of some sort. She opened it and took out a computer-chip-shaped item, with image of Purple Heart's face on it. She put her left hand in front of her, facing the device at herself. The monster attemped to attack her.

"Neptune-san!" She exclaimed, dodging the attack, then insert the chip into the first slot of the device.

PURPLE HEART!

A silhouette of Purple Heart appeared to the left side of her. She then took out a second chip, this time with Black Heart's face on it.

"Noire-san!" She inserted it into the second slot.

BLACK HEART!

A silhouette of Black Heart appeared to the right side of her. She then pressed the button on the device, and raised her hand above her head, a power symbol decended onto her hand. She put the power symbol onto her chest, the 2 silhouettes then slamed into her. The monster tried to attack again, but a light pillar appeared, blocking the attack. Noire, who had reverted back to her normal form, was hiding behind a tree with Neptune leaning next to her, realised what this was.

FUSION HEART: BLACK PURPLE!

The light faded away, revealing a figure taller than the mysterious girl. She had one long braided pink hair, one blue and one lime green eye, both of them had a power core symbol in the middle. She wore a single black hair clip to the right of her hair with glowing blue D-Pad shape on it, and a black body suit that exposed her chest somewhat. She also wore gaunlets with mixed color of purple and white, and black boots also with purple and white coloring on it.

"I am… Fusion Heart!" She proclaimed.
