Above the pacific ocean, is a rainbow portal. Exiting the portal is a mature redhead woman exited.
"At least, I got the place right but I can tell I'm not in the desired point of time"
Akane began to fly toward Japan while keeping herself invisible. She flew at a moderate speed not breaking the sound barrier.
It took her a few hours to reach the nearest island she is searching for I-Island. Flying over it, she spread her En throughout the whole island, millions of photon particles appeared covering each and everything living or non-living thing on the island.
These photons scan everything they touch and obtain information transferring it to Akane. She used her technomancy power in conjunction with spiritual sense and then gained the knowledge the database contains. She decided to call this 'Territorial analysis'.
"So, he still has yet to make the quirk amplification device. Nevermind, the information on genetics and mechanism of quirks is enough and they even have information on trigger though, it seems it is still is in development"
She then got the map to musutafu from the database teleporting there in a flash. She appeared on top of a building.
She scanned the entire city with her 'Territorial analysis', her general En can scan up to 100's of kilometres easily, even with 'territorial analysis', it doesn't affect her.
After getting the layout of the city and information on families. She found that Izuku midoriya is still a few months old.
"I can mess with U.A while I stay for research here. Not to mention, the technological advancements of this world are not that bad."
She then shapeshifted her body into a baby, a pretty one at that with shapeshifting power turning her body completely weak at least physically. A basket formed around her body with a comfy blanket covering her. She teleported near a mansion and began to cry. With the information she gained, one of japan's most influential couple should be passing through.
Mrs Aoki and Mr Aoki, a recently wedded couple, have everything they could wish for except they couldn't have children due to some circumstances.
They are just returning from a party but then, Mrs Aoki heard a cry of a baby coming from their backyard. She immediately rushed along Mr Aoki to see a cute baby crying in a basket. It is obvious that the baby is abandoned. Mrs Aoki immediately rushed and picked the baby in her arms as it begin to rain.
"Gasp! How could they abandon such an innocent and cute baby like that"Mrs Aoki exclaimed, she could see the baby is just fine and healthy. She is also so cute, she couldn't understand how can someone abandon such a baby.
"Let's talk about it later, for now. Let's get inside the mansion first, it is going to rain any second now" her husband replied as they both got inside.
Even the husband felt it is cruel to abandon a child but he is having some other thoughts like how can someone enter their backyard when they have such a good defence system surrounding their mansion.
'There are chances that they jumped over the wall but for that, they need a quirk that can let them do a super human jump or they could have had a teleportation quirk but why leave a baby here of all places? Are they expecting us to adopt the baby?'
With those thoughts in mind, both husband and wife reached inside the house.
Mrs Aoki began to sing a lullaby making the baby sleep.
"I know what you are thinking, do you think we can adopt the baby since you know...."
Mr Aoki sighed "I know Nina but....let's do a DNA test for her and see if the baby's parents are alive. If we can't find anything about her parents, let's adopt her officially"
The next day, they did the DNA test but they couldn't find any match. Knowing, they can't do anything anymore. They adopted the baby officially. Mrs Aoki is actually glad about it, Mr Aoki while he didn't mind adopting the child, he concluded that someone must have used teleportation quirk on the baby from somewhere outside Japan, he felt pity for the biological parents but he is also happy that he could raise a child himself which was an impossible dream before.
For the next few years, Akane is raised by the Aoki couple. She used one of her hatsu's making the couple name her Akane in this world too. She didn't brainwash them, she came here for research and to enjoy a bit in this colourful modern world. She didn't like the HxH world that much due to it still being backwards in most of the places with few cities. This is a much more advanced world which she liked.
As for the couple, they adored Akane a lot. They realised she is intelligent at such young age, though it didn't make them enjoy childish moments of Akane, they were happy for her since they don't need to worry about her in future.
Akane also began to like her new mom and dad as they took care of her A LOT like they could go full yandere if necessary for her.
Her parent's quirks are interesting, her dad has a 'parallel memory' quirk that allowed him to analyze things 100 things at once, making him one of the strongest minds while her mom's quirk is 'super-grip', she can walk on walls like spiderman and her hands have enough strength to put a dent in 1-inch thick metal rod.
She must say, the couple is extremely rich and powerful in Japan. They spent money like water but they still have a lot left in the bank that can be spent for the next 150 years without a care, it is mainly due to her father and mother being the CEOs of major companies and owners of multiple businesses. They also have shady dealings making them have connections but they are not completely criminal.
Akane spent the 4 years doing nothing but enjoying the luxury and pampering her new parents giving.
Today is 4th year since Akane is 'born'.
"Let's open Gacha tickets. I should have some 1200 GP by now. System, open 1 high tier Gacha ticket and 2 mid-tier Gacha tickets"
[High tier: sky-god slayer magic
Mid Tier: Warhammer titan, Darkness(Immense)]
"Great, I love sky god slayer magic visually, it has potential too. Then, war hammer titan is meh, I would have liked female titan more. An increase in Darkness reserves is welcome."
Happy with the rewards, she felt the power of her darkness increase vastly. She could also feel the amount of darkness is so much higher that her previous reserves looked like a joke. This darkness could destroy half of the earth, this darkness also made her extremely strong physically despite having a weak body now. Then, the knowledge of sky God slayer magic spells along with new magical energy filled her, due to the sky God slayer magic she could feel her magic reserves along with strength, durability and speed increased immensely.
She didn't change them though, she decided to slowly release her physical capabilities as she grows up anyway.
Akane went to her backyard, sensing no one she sucked all the winds from the surroundings.
She stretched her palms, as powerful black winds manifested spinning above her parm like a mini whirlwind.
"The winds are...powerful. I'm not even using an ounce of power yet they are strong enough to lift me and they could even shred human flesh easily. I can even manipulate the power of the winds without limits, Not to mention.."
Akane stepped onto the space in front of her and stood on nothing but space. She can walk in the sky like she walks on land.
"This changes things, this power is too visually stunning ....i wanted to show light force manipulation as my quirk but...whatever"
She didn't care that much about most of her other powers but she liked sky God slayer magic after vector manipulation.
But she is still deciding to show which power she has officially among the plethora of powers she has.
