Monkey D. Aika

Monkey D. Aika is a young pirate-in-training, and the cabin girl of the Straw Hat Pirates, being one of the crew's three youngest members. She is the younger half-sister of Monkey D. Luffy, daughter of Monkey D. Dragon and Kamiya, granddaughter of Monkey D. Garp, adoptive younger sister of Portgas D. Ace and Sabo, and owner of the young Akita puppy, Kumi. Her dream is to become a great pirate like her older brother when she grows older, as she continues to be brave and standing up for what's right in the midst of a crisis no matter how many times others tell her to stay put.

This is completely wrong, I don't think Luffy has a half-sister. And I think that it's just fan made since Aika has not been mentioned in the anime. And I never seen someone talk about her even Oda the writer himself.

He is right Aika is not even a character in the One piece fandom this is 100% fan made and none of this is real. Luffy has no biological siblings confirmed by Oda himself and his only siblings are Sabo and Ace through a promise to become great pirate brothers. In fact even if this person was lying about the true events in one piece the evidence is so incorrect that unless you haven't seen episode 1 of one piece you would fall for it. However if you have seen episode 1 of one piece then you would understand that luffy would never have someone work under him no such person in the show has EVER been a cabin girl for luffy and that picture of so called Aika is from Sword Art Online which is a whole entirely different anime.

## Appearance

Aika is a short, petite young girl who shares a striking resemblance to her half-older brother, except she has pale skin, bright and large black eyes, long, dark hair that reaches down to her hip, and a bright-blue butterfly clip on the right side of her hair.

Like Nami and Robin, she changes her clothes daily, but mainly wears a dark red cowgirl hat on top of her head, a simple sky blue T-shirt with the word "DOG" written in big white letters on the front, a magenta skirt with a pink, cherry blossom print on it, and a pair of black sneakers with white laces on top of white socks rolled up to her calves.

When using her Devil Fruit powers, her appearance is changed. She has the form of the extinct honshu wolf, with tan coated fur around her body with a cream-colored underbelly and muzzle, two pricked ears, and a shiny gray nose. Her black hair now becomes a blackish-blue color, and her eyes now become golden-yellow with a vibrant aura. She maintains her butterfly clip and only keeps her top clothing; the bottom portion of her clothing disappear, but will reappear if she turns to her human form.

## Personality

Much like her boisterous and energetic brother, Aika is a cheerful, carefree, silly, and optimistic young girl, with a peculiar mind when observing things from her perspective and a gluttonous appetite for food (mainly cookies). She is quick to make new friends and is more than willing to help those in need whenever she can, even risking her own life to ensure their safety at such a young age. She takes the time to reflect about her surroundings, concluding to insightful wisdom(s) about love and bonds. Because she wants to help her crew and not be unless to them, she can be very reckless and stubborn (especially in a fight she wants to join only to be held back), refusing to listen to those older than her because of her determination to help her friends and not wanting to suffer the same pain she endured.

Also, due to eating her Devil Fruit, Aika has developed a preference for being in her animal form more, especially after meeting the Straw Hats, and because of this, she has feral tendencies for hunting small prey, but she does not experience for killing her quarry, opting instead to release them after catching them.

When first introduced, Aika was very timid and afraid, talking only to her best friend Kumi, and being shy when trying to speak with someone new. This is because of her isolation after the loss of her family and being rejected by the other children due to her Devil Fruit powers; she knows better of knowing what it's like to suffer. This however changed when she met Luffy the first time (who she doesn't know as her older half-brother) and gave her the courage to speak for herself. Following Caesar Clown's defeat, she was welcomed by the Straw Hat Pirates and now became a member of their crew, which helps her continue to grow and become a more open person.

The one thing that Aika fears the most in her life is the Marines, especially their fleet admiral, Akainu (the man responsible for the death of her mother and the islanders because of her heritage to Dragon). Whenever she sees the insignia, she will have a mental breakdown and relapse into her timid nature for about an hour. Even mentioning the Marines makes Aika afraid and scared, causing her friends to hide her inside the Thousand Sunny until it's safe, proven her fear after the pain she suffered. Over time, she becomes less afraid and is more than willing to fight them, even standing up for her friends and brother despite their attempts to keep her safe. Despite hating the Marines, she knows there are some that aren't evil and only do it based on their convictions, as seen in her relations with Smoker and Tashigi.

As a person with the middle initial D., Aika also has the common trait of not fearing death even though she is young. No matter how scary things are or how dangerous the situation is, she always stays true to her word and tends to keep promises to those she calls her friends. She would even laugh in the face of danger and keep a smile on her face to stay well, despite being afraid on the inside.

Because she is so young, she has a questionable mind when hearing things that are suppose to be said when she is older, like hearing coarse language, sex, drugs or even blood makes her wanting to ask her more older friends what each one is, making them tempting to tell her in her later years as a teenager.

## Abilities

**Dog-Dog Fruit: Honshu Wolf Model**: A Zoan type Devil Fruit, this fruit allows the user to transform into a honshu wolf, whose strength, speed and senses are equivalent to that of an actual wolf. In her full animal form, she is more adapted to traveling in rugged terrain, such as forests and tundras. Having a Carnivorous Zoan makes her more predatory and bloodthirsty, which is called "**Berserker Mode**", and in this state, she gains a rush of adrenaline, but cannot tell the difference between friend and foe.

* **Electro**: In her hybrid form (or sometimes her full animal form), she possesses the Mink Tribe's signature technique that allows them to channel electricity through parts of their bodies to deliver shock damage to their targets.

**Haki**: There are normally two types of Haki regular people can tap into: the Observation Haki which allows individuals to sense the presence of others, and Armament Haki which allows individuals to create an invisible armor around them. There is however a third type of Haki, Conqueror's Haki, that only a few individuals can use. Despite her young age, Aika is one of these people to learn Conqueror's Haki.

* **Conqueror's Haki**: The ability to knock out someone else or a large group. While inexperienced users are restricted to intimidating one being or blindly knocking out any with weak wills around them, those with more expertise can pick out weak willed individuals in a large group to knock out. Can also be used as an AOE energy blast and to tame animals.
* **Observation Haki**: A form of Haki that allows the user to sense the presence of his opponents. A user of this type of Haki can predict an opponent’s moves before he gets hit. This works by showing the user an image or brief “premonition” of what the opponent will do, manifested as a mental image in the user’s mind’s eye, and the damage the user will take if the attack “hit” for real. It appears that the more killer intent the enemy has the easier they are to predict, though more efficient users can predict future moves regardless whether there are ambient murderous intents or not. Including the distance, location, and where the opponent may strike next.
