Just as a warning, this crossover is going to be a short story, thus about 10,000 words at most. Plus, there's going to be a larger story based on Gundam 00, so don't expect too much.

Also, this takes place in between Episode 11 and 12 of the first season. Thus, the entire story is about an episode long.

As a warning, although there are no original characters here, expect to know both stories to understand what's going on.

"I would like to address this statement to every single human being born and raised on Earth. We call ourselves simply Celestial Being. We are a private armed organization in possession of the mobile weapon Gundam."

"The main objective of Celestial Being's activities is to completely eliminate acts of war from this world. We do not act for our own benefit or for personal gain. We have chosen to intervene for the greatest goal of all to rid ourselves of the scourge of war."

"As of this moment, I make this declaration to all humanity. Territory, religion, energy no matter what the reason or excuse if there is an evident act of war being carried out, we will commence intervention with our force. Any country, organization or corporation that promotes war will also be a legitimate target for our intervention."

Orbiting the Earth and its ringed solar array was the Ptolemaios mothership of Celestial Being. Sumeragi Lee Noriega was having a drink of hard liquor while having Aeolia's message play in the background of her room. While she was used to heavy drinking, this was a special time following the recent operation.

Six months already passed since Celestial Being revealed itself to the world, commencing more than 60 interventions across the world, whether they were minor countries or superstates. Celestial Being was already both famous and infamous for their acts, both scorned and appraised for their attempts to end warfare by force.

Progress was already made well when it came to actions against the superstates. Thanks to the severe damage it took in Moralia, the Parliament from the Advanced European Union begun abandoning its military expansionism in favor of financial support.

The recent operation struck a major blow to the Human Reform League, the only one of the three superstates that challenged Celestial Being. The recent operation resulted in the destruction of the Superhuman Research Institute, a building in the Quanqiu Colony that turned innocent children into killing machines. The whole incident was then leaked to the world, forcing the nation to back down and clean its own mess. While it's already been rumored that the HRL and AEU were already working with the Union, the last of the three superstates, Sumeragi's predictions showed the scandal and backlash will delay any joint operations between them for at least for a few months.

In less than an hour ago, Sumeragi finished sharing a weaker alcoholic drink with Allelujah Haptism, one of the Gundam Meisters who piloted one of the named machines. He just came of age, so this was a perfect present for him. Not only he'll be able to join her in her drinking sessions, but he's free from the past that corrupted him.

Or at that's what she thought...

The dark screen suddenly shone in her eyes; the only reason it would do that is if the Veda supercomputer found anything useful. When Sumeragi checked it out, it turned out to be something else coming from the Superhuman Research Institute.

I thought the operation was over. So how could it…

Before she continued, she tapped the file to read the reported contents and plan. While the Research Institute was already known for human body reconstruction, the operation's name and following data reveal something else just as troubling.

"Operation Charlotte...If this is what Veda wishes, then we'll have to proceed with this operation," Sumeragi spoke to herself. "At least, Allelujah will not be alone."

A few days later, within the narrow Ptolemaios bridge, three of the Gundam Meisters joined up with the rest of the crew.

"So we're going through this, aren't we?" Lockon Stratos did not hold his frustration over the operation that meant close contact with other people.

"Setsuna has already been given the mission details," Sumeragi responded, mentioning the other Gundam Meister who was not in the room. "Within the next few hours, the Gundams and their Meisters will establish a perimeter as he temporarily attends the Hoshinoumi Academy for investigation."

"The risk of the operation is too great," Tieria Erde may follow Veda's orders intimately compared to the rest of Celestial Being, but even he had reservations. "This unknown info is too little is too little of a reward to be worth risking our identities."

"Even so, it's Veda's recommendation," Sumeragi replied, having Tieria stand down for the moment. She then faced the third Gundam Meisters, who'd have a more intimate role, though not as much as Setsuna. "Allelujah, are you willing to take part in this operation?"

"I will be fine," the last Gundam Meister responded. Despite having a few days to recuperate, he didn't appear to be a position to fight. A journey to a school, on the other hand, was something he can easily participate in.

"Very well, we'll have you three launched as soon as you're ready." As the three Gundam Meisters confirmed and left the bridge, she then gave orders to some of the crew. "Feldt, Christina, as soon as they launch, I have another mission for you. Once they've launched, I want you two to start an information hunt along with Veda."

"Huh?"

"I'll tell you more after the operation begins."

Sumeragi didn't want to exactly tell what she had in her mind, but Allelujah's past and the experiments done at the Institute proved that similar research could be conducted elsewhere. If that's the case, then this will have to be something they should intervene in.

Operation Charlotte...if what the data says is true, then for the sake of these kids, we should end this kind of madness as well.

Once again, not too much. Either way, hope you had interest.
