"Aiko Narukami, Is a Character you should quite be familiar with as of late, she might look like an innocent little girl or a normal teenager, but that's not it, or that's one of her origins."

"I made her an active character when she first appeared in Persona Record: Magi Arena."
Where she is 4 years old, she is an OC made for The Persona Series."
As by her last name it would tell you of her being a fictional daughter of Yu Narukami the Persona 4 Protagonist."

"There can be Many origins of Aiko of how she can be Yu's Biological Daughter.
Her mother could have died like what happened to Nanako's Mother, or could have left Yu over some issues, but one way I have decided to use her character is she doesn't have a mother but is somehow Biologically Related to P4 Protagonist."
I use mythology with it too, if you know the origin of Athena I drive into that to make Aiko for not having a mom make sense."

"So we know that Athena when she was born, she popped out of Zeus's Head, and literally demanded all the stuff that she needed, and she became his Favorite child too----or that's the story I was told when I was young.....and dumb."
But that's what I use, so let's get with Aiko's Backstory, I'll be using what I wrote on the Animo Account I did for her."

Yu Felt Pain Coming Though Him, Making His Friends Worry as He Collapsed On the Ground as a Bright Light Emerged and The Crying Of a Baby.
In Yu's Arms Was a Baby Rapped In Cloth, clutched in Yu's Arms.

When Yu Is Taken To The Hospital.
The Baby is Confirmed To Be Yu's Daughter Due To a DNA Test. But The Mother is Unknown, Only Having The Same DNA as Yu.
Dojima is baffled by This and Gives Yu an Option, Sense He was Still Young (He's 20)

To Keep The Baby Girl or Give it Up For Adoption.
With How The Baby Birth is Strange.
Yu Wanted To Keep The Baby and His Friends agreed with Him to Keep the Baby.

Yu Named Her Aiko Meaning "Little Love One".
They Had Informed The Shadow operatives of Aiko's Birth.
Being a Daughter of a Wild Card, Meaning Aiko has Access To The Wild Card Ability.
(This can be seen playing out when you read Magi Arena, or it will be mentioned sometimes).

(Abilities)

Being The Daughter of a Wild Card User, she has access to a multiple ray of Personas.
But she uses two Personas In particular, Hemera and Amaterasu."
Hemera is her first persona an artificial persona from Elizabeth the Velvet Room attendant of Persona 3.

"Amaterasu is her Real Persona, You may know Yukiko Amagi also used this Persona as well."
Amaterasu Could also be Aiko's Recarnation something I've been hinting out in the Persona Record Series."
But this is how she uses them.

"For Hemera, She is the Daughter Nyx and Erebus, in Greek mythology, Unlike Her Other Main Persona, She Awaken To Hemera Too Early At The Age of 4 Making Her an Artificial Persona-User.
She Had To Take Supplements Given To Her By The Kirijo Group To Keep Hemera From Going Berserk."

"Her Second Persona is Amaterasu, Originally Yukiko Amagi's Persona's Second Evolution.

After Yukiko Unlocked Her Third and Final Known Evolution.

Aiko Came To Have Access to Amaterasu,
When She was 15 years old, Helping The P6 Protagonist's Team and The P6 Protagonist Him/Her.
With The Help Of Amaterasu's Power.
Hemera Became No Longer an Artificial Persona, and Became a Regular Persona of The Wild Card, To Everyone's Relief Who Knew About Her Artificial Side.

She uses the sword, Hinokagutsuchi, and can use different elements, using these elements the gem on the center of the sword changes to the respected skill color.
If your familiar with Atlus's Games and the Skills use you should be quite familiar with them.
Also with Hinokagutsuchi, Aiko can control Hemera with Hinokagutsuchi as well, and she came disguise Hinokagutsuchi into looking like a Katana too.

(Special Abilities)

Aiko Narukami comes with Special Abilities, In the PR Series, she has been seen to use Navigation, but she has one ability she was given to by Elizabeth."
This Ability is "Persona Transfer".
Aiko To Transfer One of Her Main Personas To Another Wild Card User Temporary.
But If The Wild Card User is Not In a Perfect Match To Aiko's Social Level.
Will Cause an Electric Rappelling Zap.

(Summoning)

"Aiko does different ways to Summon her personas.
To Summon Hemera She Uses an Evoker Given To Her By Mitsuru, Who She refers as The Woman With Red, When Forgetting Mitsuru's Name.
Her Evoker Instead of Having Something Engraved Like S.E.E.S, Her Name A.I.K.O is Engraved On Her Evoker."

To Summon Amaterasu She Crushes The Fool Arcana Just Like Her Father Yu and His Friends
She Can Also Someone Hemera and Amaterasu Together at The Same Time to Do a Powerful Combo Skill.

In PR Series, Aiko uses Hinokagutsuchi to slice the Fool Arcana to Summon Amaterasu.

"When does Combo even if it's powerful can take a lot of HP and SP From her, she'll become very tighter may have to nap it off and may look like she's dying but she'll be alright.... Hopefully to whatever you use of it."

I also have said that Aiko is a Free to use OC, but If you want to tell me or get permission to use her I'll still let you.
