The Costume Party: Sustainer of Heavenly Principles (Com)

 A commission for Last_of_workers

Jenna considered herself the badass loner type of girl, so when it came to cosplaying she only did characters that matched that, which is why the character at the beginning of Genshin Impact that beats the daylights out of Aether and Lumine caught her attention.

There wasn’t a whole lot of information about the character, and that made her very mysterious, which made Jenna love her even more. So that was who she decided to cosplay, which is what led her friend Turner to invite her to his genshin cosplaying group.

Thanks to that she has a lot of awesome new friends, even if she’s too proud to admit it. Because she was part of the group, that meant she had been invited to Turner’s party tonight, which meant she was going to get to wear her costume.

So she got it on and walked over to Turner's house. Despite living so close, she still showed up a bit later than the stated time for the party, so a small number of people had already arrived and started mingling.

Jenna saw Beckham who she was really close with in the group and went over to speak with him. He was impressed by her costume, but his compliments about it felt more directed at her instead of the costume itself, which Jenna didn’t mind, she felt good and liked showing it off.

After talking a bit about her costume, Jenna told him he was great too, not because he looked good in it, but because he looked terrible, but in a funny and good way, which was what Beckham was going for.

Jenna said she had to get a picture with him, as she needed proof she met the tallest Paimon. He was happy to do so, as he also wanted a picture. After that Jenna went around chatting a bit with everyone and showing off her costume.

She goes to the kitchen to grab something to drink, and as she does she notices a child on the floor dressed as Qiqi. The girl looks up at Jenna and stuffs her face with pretzels without saying anything. Jenna nodded, grabbed her drink, and left her to it.

Jenna then went back into the main room, which was when Beckham waved her over. He said they were starting up a group to play Genshin, he asked her to join, and there was no way she was going to say no.

So she pulled out her Nintendo Switch from her bag and sat on the floor by Beckham's feet. She joined them, deciding to play as Beidou since the character she was cosplaying wasn’t a playable character.

The group did attempt to do things like treasure hunting, but Luke kept stopping and playing meme songs on his instruments, and it wasn’t long before the rest of them joined him, and before they all knew it, they were goofing around.

The rest of the party had gathered around them and had made their own groups to play, with Turner and Dustin being the only ones not playing, but to be fair Dustin wasn’t that into Genshin yet, or he’d know he was cosplaying Miss Hina.

Everyone was having a blast when the bright light filled the room and blinded them. Jenna was still rubbing her eyes when Ariel’s Ruin Mech suddenly came to life and picked her up. Once her vision came back and she looked at it she was amazed.

But that was mostly because she didn’t realize it was real yet, she thought it was just a very well-made prop, but then Beckham started to scream. She looked over at her, and the once tallest Paimon was now an ordinary-sized one.

As sad as it was that tall Piamon was gone, it was a hundred times better to have a life-sized one that actually looked like her literally floating around, but Beckham was far from the only one that changed to match their costumes.

Everyone in the room had become their characters. Jenna was so excited, it was so amazing, even if not everyone thought so. She then realized that if everyone else changed, she must have as well. She looked down and her heart started to flutter with how excited she was to see her new self.

She ran out of the house before the rest of the group even decided to break off and inspect themselves privately. She went outside and around the corner. She immediately grabbed her breasts which had gotten much larger.

They were heavy, but they were nice and round and very full, suffice to say she was really happy with her new cleavage. She ran her hands down her costume, her costume had been tight before, but with her waist getting skimmer and her hips becoming much wider, it was much more noticeable.

Still, though she loved it, she did have a decent body before, but now she was smoking hot. She was so happy she didn’t realize she had created a cube, so when she moved her hand to keep feeling herself up, she sent it flying away.

It hit the wall of a neighbor's house and broke it into pieces instantly. Jenna didn't notice that, but she did notice when she created her second cube. She was entranced by it, she then heard a squirrel running across the top of a fence nearby.

She looked at it and smiled. She sent the cube flying at it and as she hoped, the squirrel was trapped inside it. Jenna was then able to move the cube around, even at a distance with ease. She played around with the cube, shaking it, seeing how high it could co and even dropping it.

The squirrel inside was completely unaffected by all of it. Jenna then snapped her fingers and the cube vanished, along with the squirrel, going who knows where. Jenna then looked at the ground, she not only changed into the Sustainer of Heavenly Principles but also had her powers.

Jenna, being a badass, took flight without a worry in her mind. She shot through the sky flying around like a jet plane performing for people. She was having a blast, but then something came around to try and ruin her fun.

A group of villains who could fly approached her in the sky. Among them was Daybreaker from my little pony, who seemed to have turned into a real pony. Aquamarine from Steven Universe who was so tiny and flying using water wings.

Finally, there was Hobgoblin from Spiderman who was flying around on his glider. The group asked Jenna which side she was on. Jenna, annoyed they were talking to her, asked them what the hell they were talking about, all while she created a cube behind her back.

They said it was chaos out here, and it was good guys versus bad guys, and if she was a bad guy, she was to join them, and if she was a good guy they were going to kill her. Jenna looked at them annoyed, then she sent her cube to Aquamarine.

She caught her and made her disappear, and then Jenna started to fly around to avoid attacks from the others. Neither of them was very strong, at least not compared to her, so all this fight was to her was a nuisance.

So she ended it quickly. She summoned about a hundred cubes, then split them into two groups and sent the swarms after both of her remaining enemies. They could only avoid them for about a minute before they were trapped and sent to the unknown.

Jenna hadn’t realized it before, but someone else had approached to try and help her in the fight but stopped when they saw she had it handled. Jenna finally noticed them and looked over to see a supergirl.

She sighed and asked her what she wanted. Her first question was what Jenna did with those that attacked her. She told the supergirl she had no idea they could be dead, or simply in another world, either way, she didn't care.

That seemed to upset her, and she demanded she try to let them go or at the very least stop using her power. Jenna scoffed at her and asked who she was to demand she do anything. Supergirl turned a bit red.

She said she was Supergirl, a hero of light, even if an hour ago she was a guy who put on the wrong costume. Because of that, it was now her job to protect people, and that included evil people from other evil people, that way they could all be arrested.

Jenna rolled her eyes and told Supergirl to get lost. The super girl refused and flew at Jenna as fast as she could. Jenna quickly used the cubes to make a wall, which caused the supergirl to stop right before touching them.

The super girl then started to use her laser beams on them, but they did nothing. Jenna sighed again and told Supergirl she was an idiot. She was a magic user. The supergirl’s eyes got wider, and she suddenly tried to turn around to fly off, but it was too late.

Jenna had already made another wall of cubes, and she had completely surrounded The supergirl. The super girl tried to use her freeze breath, but that did nothing, then she tried to punch one of the cubes, which only activated the cube, trapping her in it.

Jenna brought the cube towards her and then told the supergirl she should have just left her alone. Jenna then snapped her fingers, sending the supergirl to join the others. Jenna then looked at her cubes, it would be a waste to not use them.

So she looked down, she waved her hand, and told them to go out and collect more people for her, and if they couldn't find anyone, to just hit something and break it. Jenna then flew off letting the cubes do their own things.

She made her way back to Turner's house to find everyone in a better mood playing around with their powers and weapons. She acted like she’d been there the whole time and joined them in having fun, not letting on about what she did, or her slightly evil new addition to her personality.

The following morning she woke up early and started to mess around with her cubes, it turned out she could resummon them once they were gone, and it also turned out she had about several people and creatures now in her collection.

She was going to release them, but that new part of her personality came out again. She saw no reason to, and in fact, she felt as though she needed to keep doing it. She was the Sustainer of Heavenly Principles after all, and it was her job to denounce the arrogation of mankind.

Before she did anything though, she got a message from Turner saying they were all likely stuck like this because of some witch. Jenna smiled, that was good, she really did enjoy her new body and powers, but she was also going to enjoy fulfilling her new mission.
