6 Ivan Is Back.

At this point in his life, Ivan found that time seemed to flow quite fast. He always had something to do, something to learn, or an ability to master. In his current child's female body, he felt angered.

His mind kept telling him that he was still in his male body when in fact he most certainly was not. There were a few times he awoke in the morning and had feelings close to phantom pains from missing a limb. 

That was quite a weird experience, but he quickly learned to ignore those irritating feelings. On a more positive note, it seemed that the original Momo's quirk Creation had been forcefully evolved when it reacted to the Black Templar Gene Seed and the Heavenly Restriction.

The evolution granted Ivan a basic instinctual control over his body cells just what he wanted. However, he did not dare mess with his body just yet without background information. He could accidentally turn a tumorous blob by mistake and end his second life. 

It was great that his parents began to support his education when they found out how Creation works. As such, they bought him plenty of Science books so he could learn more information to make use of the quirk. 

He quickly thanked them as he could read through a book in just a few moments with his Space Marine brain. He was thankful for being one as this super brain seemed made for this quirk that needed knowledge. 

Every time he read a book, his brain took in the information, broke it apart, and stored all the useful knowledge. Though it was up to him to understand that knowledge, he was pretty clever. 

Meanwhile, he could purge anything useless from his mind meaning he only had to read a book once to learn the knowledge within it. However, as his quirk was at a higher level than the original Momo, he had to study even more.

Which was barely a bother so he read through books on metals, alloys, ceramics, composite materials, electronics, firearm components, explosives, anatomy books, and languages. 

The biggest cheat code at his disposal was the internet. While books often contained specific knowledge, the Internet carried broad knowledge. By going through hundreds of articles, videos, and detailed medical and science reports he had begun to truly understand his anatomy and quirk. 

However, he did not just focus on that as he also had his body to train. Just having a Space Marine body was not enough, he had to push it to the limit. Just like Maximmion Voss, one of his brothers through their gene father, Rogal Dorn.

As he did have his Gene Seed through the Black Templar lineage, he was technically a child of Dorn. At the moment he was a Daughter of Dorn, but at the rate he was learning that would soon change. 

As for Maximmion, he was an Imperial Fist with a gene defect that made him much shorter than standard Space Marines. In order to compensate, he trained so hard that he became stronger than a standard Space Marine. 

Ivan planned to do the same as he did not want to waste his potentiol. That was how Ivan spent his time for the following 4 years making him 8 years old. 

---

Currently, Ivan was outside the manor sitting under a large tree writing in a notebook in Old Norse. He had chosen the language in case his parents found it as the book had personal information from his past life in it.

On top of that, were a few detailed anatomical drawings of his current body and what he wanted it to look like. In 4 years, he had discovered how to shapeshift certain parts of his body, but a full body shift was much riskier. If a shift went wrong, he could find his eye on his neck and he would be turned into a disgusting abomination. 

"It should work in theory, but that is not good enough." 

He exhaled which turned his breath into mist. It was currently December and snowing, but he was still wearing a light sweater. The cold barely affected him and he found it quite enjoyable. 

He looked over the diagram of his current body as he had to know everything. He was currently 5'11, weighed 240 pounds(108 kg), and all the Space Marine Gene Seed were up to a ratio of the current body. 

A female body which for an 8-year-old Japanese Girl, was HUGE! However, with Space Marine Gene Seed and Heavenly Restriction added to that it did make a good bit of sense. He also had to note down the few edits he had made to his body. 

'First, the teeth. I did change them and my jaw structure to be more like the Space Wolves, the claws. I made them retractable much like a cat and strong. I made my eyes stronger and more attuned to more Light types. That should be everything.' 

Once he wrote all that down, he smiled as he felt he was ready to start experimenting with more serious shapeshifts. Before he got to do that, he heard heavy footsteps walking toward him. 

He looked over and saw Gustave walking toward him. After 4 years the croc was quite big as he was 3 meters long. By crock standards that was on the smaller side, but his age was the shock. Most crocs grew slowly, but Gustave's quirk-enhanced body had a higher metabolism than most reptiles. 

It led to a faster growth rate and increased intelligence from what they had seen. Ivan smiled as Typhon was resting on his snoot. Gustave was the warmest creature around as his body was warm from his fire quirk. 

"Miss me?" 

Gustave rushed over to him before plopping down next to him for pets. He was quite affectionate for being a giant crocodile with fire abilities. He ran his hand down the croc's snout, but he did not forget Typhon his dragon. 

"It's weird that you like swimming when you are a fire crocodile."

Typhon had to agree as he jumped onto his shoulder. His minion used fire powers but preferred to live in the water rather than dry land. Why couldn't he just pick one? As for Gustave, the happier he got the more the cracks between his scales glowed a fiery red. 

Ivan f crowned he ran a hand through his hair. His parents kept it quite long which made sense as he was trapped in a female body. He hated every waking moment of it and distracted himself with anything to forget. Though, if he was right he could in theory change that right now. Just as he read through his notes a few times, Yoshimura came out of the house 

When she saw him with his pets, she smiled and walked over in a big jacket. 

"Momo. Your mom was wondering if you are fully packed?" 

'That name again.'

He kept his face calm as he looked at his journal. 

"Yeah, I am." 

Yoshimura walked over and looked at the journal that Ivan had written in. When she saw the runic language she got curious. 

"That's new. What language is that?" 

"Old Norse. I thought it be cool to write in it." 

Yoshimura nodded as she looked at the runes. 

"Sometimes I am jealous about how fast you learn things. How did you learn it?" 

"I looked at old Norse Mythology texts and some Norse dictionaries. It did not take me long to piece together the language."

Ivan closed the notebook and handed it over to Typhon who snatched it up in his mouth before swallowing it. He served the same purpose as Toji's Storage Curse so he stored away Ivan's creation. 

"Neat." 

Ivan stood up popped his neck and stretched his body out. 

'This is it. Either I sink or succeed.'

"Yoshimura, I want you to not panic about what you will see."

The Red Haired maid was not sure what he meant. 

What do you mean?" 

Ivan did not respond and placed his open palms on his face. He closed his eyes and focused on his entire body. He remembered his sketches, all the observations he had taken, and remembered when he edited his body. 

Under Yoshimiura's eyes, Ivan's entire body seemed to begin to warp and shift as if fluid. The transformation was seamless and quick as it only lasted a few moments, but when it was over, 'Momo' was gone. 

In 'her' place stood 'Ivan' in his full glory. He of course modeled his male body after Toji Fushijuro as Toji was awesome.

Yoshimura's mouth dropped as Ivan began to stretch and pop his body. He took a deep breath and placed a hand on his chest. His clothes which were formed by his quirk changed and grew to suit his new body as it was bigger. 

He was now 6'1, much more muscular, and most importantly his male member was back. He leaned back and took in a deep breath before he began to laugh in an absurdly deep voice. 

'I am back.' 

The extra height had come from repurposed 'fleshy' bits from his female body. 

"That was easier than I thought. What do you think? Hot right?"

Yoshimura was currently in shock. She just watched her friend's daughter shapeshift into a shockingly handsome male. A young teen as the face still had hints of youth.

"M-M-M-M-Mo-Mo-Mo-Momo? What? How? Why?" 

He patted her shoulder gently. 

"I don't have that name and Relax already. You knew my quirk could allow me to shift parts of my body. I just found a way to fully shift my form. So, what do you think?" 

He flexed his frankly massive arms as the veins in them bulged. It seemed the moment he was back in a male body, his Gene Seed organs were running in hyperdrive. It was designed with male anatomy after all and was now as it should be. 

His mind finally seemed to settle down after being trapped in a female body for 8 long years. He enjoyed the feeling for a few moments before he felt Yoshimura grab his hand. She began to pull him toward the manor as she had to tell Asashi and Miku. 

They had to know that this happened so Ivan allowed himself to be pulled along. Typhon and Gustave followed behind as this was interesting and entertaining. When Yoshimura entered the mansion with Ivan behind her she yelled for her friend. 

"MIKU! COME QUICK!"

Ivan rolled his eyes as he gently pulled his hand from her grip. 

"Relax will you? It's not that big of a deal Yoshimura." 

Yoshimura did not agree. She turned around red in the face and motioned for Ivan. 

"Not a big deal? Look at yourself Mo-" 

Before he got called Momo again, he stopped her. He was done with that name and his old prison of a body. 

"Ivan. It's Ivan."

Yoshimura felt the sky turned green. 

"Ivan? Did you even change your name so fast? This is not like changing the color of your nails, or your eyes. You turned into a boy in front of my eyes and fast. Can you even change back?" 

Ivan was about to answer the question when his parents Miku and Asashi came running down the stairs to see what the yelling was about. They stopped halfway when they saw Yoshimura with Ivan. 

Someone they had never met in their lives, but if he was here, did Yoshimura know him? Yoshimura waited until they were down the stairs before taking a deep breath. 

"Miku, Asashi, you might not believe this, but this man is Momo." 

Miku and Asashi both froze and looked Ivan over. How could this young man possibly be their daughter? Miku frowned. 

"Yoshimura, we may be friends, but this is not funny. Who are you?" 

Ivan pointed at himself. 

"She isn't lying. See." 

He pointed at his eyes which had black scelera surrounding a golden iris. He opened his mouth and showed them the sharp teeth he still had. And just to be safe, he showed them how his nails were black and extendable. 

He was not going to be turning back into Momo any time soon that was sure. Asashi rushed over to his child and placed a hand on Ivan's shoulder. He was both impressed and shocked. 

"How did you do that?"

Ivan smirked as he explained. 

"It's just an application of my quirk. You saw how I made my nails extendable and my teeth sharper. This is just the full application of my quirk. But if I have to be frank, I like this body far more than I did my old one." 

Asashi laughed as he patted Ivan's shoulder. He always wanted a son, but Miku was not sure she wanted another child. 

"What should I call you when you turn into this strapping young man?" 

Ivan smiled as he answered. 

"Ivan. I spent a long time designing this body. 4 years." 

Asashi was far more accepting than Miku who was still in shock. 

"Are you still my Momo?" 

Ivan opened his mouth and was going to answer when he stopped. 

"No. I would prefer to not be referred to as such." 

Miku was confused. 

"I don't know how to feel about this. It's a lot to take in." 

Ivan rubbed his chin a little as it was confusing even for him. 

"I can see why Mom. Don't worry about it, no matter what form I take, I will always be your child." 

Asashi smiled. 

"Whatever you decide is what you can be. If this is how you feel, welcome to the family Ivan by boy." 

Ivan smirked as he liked his dad a lot more right now. 

"Not really. Anyway, don't we have a flight to catch?" 

Asashi snapped out of it. 

"Damn it, your right. Yoshimura, the truck." 

Yoshimura snapped out of it and rushed outside. 

"On it." 

Meanwhile, Miku was not really convinced as her husband was. 

"I will need time, just turn back won't you?"

Ivan frowned but controlled his outburst.

"I don't know how to yet. This is still my first shapeshift so I will need time to master it and even if I did, I don't think I want to turn back." 

His mother was quite shaken hearing that. He understood, but it did not mean he was going to grant her request. But after being in that body for 8 years he wanted out of it. 

(Kinda based the shapeshifting on Mahito Idle Transfiguration. Yes, Ivan is straight so no Futa shit. That shit's weird)
