**Alpha** (アルファ) is one of the main characters of "*Rebuild World*". She is the first character to be introduced after series Protagonist Akira. She is a holographic AI, and is first describe to have been wandering around in Kuzusuhara ruin to search for someone who can complete her request until her encounter with Akira in that same place. After helping Akira avoiding his imminent death, she proposes a deal to Akira to which she will continue extending her supports in exchange to complete her only one request.

Akira rejects Alpha's offer at first, but then accepts it later. Thus from that event, Alpha now follows Akira and left the ruin.

## Appearance

Alpha is a female holographic A.I and possesses long banana mania hair, while having ceil color eyes. As she is able to freely change her looks, she perfected her appearances such that even someone like Akira was affected by her faultless beauty.

She always wears clothes that fully resembles the era of before the fall of the Old-World Civilization. The clothes itself have white and black in color, former covered most of its appearance. It also exposes many of her skin that further solidifies Akira's perception of the old-world weird and extreme taste.

## Personality

Being a high-level Artificial Intelligence, Alpha is devoted to accomplishing her duty, even as far as accepting Akira, a young penniless boy from Kugamayama's slum that only recently became a hunter a day after.

Alpha is shown to devotedly care for her client such that she willingly accept to train the utterly inexperienced Akira from scratch. That is especially true for Akira who was always seen worthless to others. But at Alpha core, she does not shred a care at all about her client other than manipulating them for her own benefits and losing said client depending on the amount of work she had put.

Whenever her clients dies, she would simply find another. If that client also dies, then she would do the same. The process repeats itself until Alpha reaches her final goal. The same *façade* can also be said towards Akira who is completely clueless about Alpha's manipulation.

## Abilities

### Support

Due to her extremely high performance and intelligence, she is able to provide Akira with various convenient support whenever he requires it. Built with extremely advanced computation capabilities, she can accurately calculate bullet trajectories, time lag, battle's aftermath, and detect enemies and biological monsters. She is also able to take control of Akira's augmented suit the moment he is in a life-threatening situation, to allow him to escape or fight back.

However, her supports are greatly reduced when inside a colorless mist, or being deep within an underground.

### Authority

Having higher privilege than other AIs, she can command lower-level mechanical entities such as the S101 big-sized multi-legged tank that was about to shoot at Akira to stop via special insignia.

Despite her privilege, when facing against an AI, to the level of having its own site to manage, Alpha's privilege only allow her to do so much before being registered as a trespasser. If a deal is successfully made, Alpha is granted to stay under a time limit while obeying other conditions made during the deal. The manager AIs are also not obligated to heed every Alpha's commands.

## Relationships

### Akira

Akira is one of the few people that can interact with Alpha, as his brain is capable of connecting to the old-world domain. During their first meeting, Alpha formed a contract with Akira. She wanted him to go deep inside a certain ruin, for which she promised to provide Akira with all the support and training he needed in order to explore said ruin.

Alpha is very dedicated to her task. She always observes Akira, learning about his personality, thought patterns, and even his behaviors, in order to choose the best possible method to achieve the most optimal outcome. Yet, at times, the way Akira thinks is still a mystery to Alpha.

She often manipulates his actions to her benefits, yet at the same time respecting his decisions and ideals so as to not lose his trust and, subsequently, their contract.

Apart from battle-related support, Alpha will occasionally advise Akira on how to manage his finances and teach him various subjects due to his lack of education. Alpha also trains Akira regularly so that his past and newly learned skills would not rust. Moreover, she sometimes interfere in Akira's social interactions when required.

Alpha tries to seduce Akira multiple times in an attempt to probe his preferences and tastes; then utilizes them to have a level of control over Akira. She tries to observe his interactions with other people as well, trying to ascertain his personality so she can further gain Akira's trust.

Alpha has concluded that Akira's sociopathic tendencies are beneficial to not only her but her cause. She deems it so because of a prior failure with a user who, right before the completion of her request, decided to terminate his contract due to his/her own sense of morality.

### Katsuya

Even if it isn't clearly stated, Alpha also has a connection with Katsuya. During Akira's fight with multiple enemies inside Kuzusuhara ruin, Katsuya was one of Akira's opponents. It is one of the critical components that cemented Alpha's connections with Katsuya.

Katsuya, having the same capability as Akira which he can connect to old-word domain, was also under Alpha's influence. However, unlike Akira, Alpha had more complications with Katsuya. One of the problems were that Katsuya had not granted her the full privilege to do anything she deemed necessary to Katsuya. Thus, her move was severely restricted.

### Shizuka

It is difficult for Alpha to understand Akira's attachment to Shizuka. However, she does not see this as a demerit since Shizuka usually provides Akira with the best equipment within her ability without causing any inconveniences towards Akira .

### Elena and Sara

In the same way as with Shizuka, Alpha finds it difficult to understand Akira's relationship with Elena and Sara. Alpha worries the two will distract Akira, which can hamper her main objective. This reason has led Alpha to consider looking for the best way to end this relationship.

### Tsubaki

Alpha sees Tsubaki both as a major inconvenience and a serious threat to her mission. She also despises Tsubaki the most.

Although Tsubaki's movement was limited due to the system's rules, she is still able to threaten Alpha greatly by almost indirectly killing Akira during his intense fight after rendering Alpha incapable to even appear in Kuzusuhara ruin.

### Olivia

Alpha hates Olivia as she was interested in Akira and wanted to work under him. Since Olivia is a high-intelligence automaton, and that Alpha is known by a few of high-intelligence AIs as a nuisance and is also the opposite for Alpha, they naturally project animosity towards each other.

## Trivia

* Despite being a high-performance artificial intelligence, and having trained with all kinds of hunters for a long time, Alpha still has a hard time understanding human emotions.
* Despite her extreme intelligence, Alpha is still unable to fully manipulate Akira, and sometimes has trouble understanding why Akira acts in a certain way.
