Akira

Akira ( アキラ ) is the protagonist of the "Rebuild World" series. He's an orphan boy with little known about his childhood other then he use to live and fend for himself in the slums of Kugamayama. Akira frequently states that he has very bad luck, seemingly because he used up all his lifetime's worth of luck by meeting Alpha. He's often associated with the number '14', when out and about. Whether or not this has some significance to the later story or just a habit of the author's, it is still unknown.

Appearance
In the starting, he is shown to be wearing ragged and torn clothes, with a dirty and bruised body due to the abysmal quality of life in the slums. He wears small ear rings on his right ear.

After meeting Alpha, and earning some money to buy gear, he is shown to wear black military-like clothes. His augmented is shown to be thin, and "greyish-black".

Personality
Akira is shown to be a very selfish and cynical individual, due to his life in the slums where he had to constantly fight for survival against not only biological monsters but humans as well.

However, he is shown to be rather caring for people that he trusts. One time, he even went out of his way to protect a person that he trusted.

Akira has a hard time coping with and understanding other people due to his anti-social nature, preferring to work alone. Furthermore, he's shown to care far more about his own safety then nearly anything else, sometimes even giving up monetary gain if extreme danger is involved.

As noted by Alpha, he divides people around him into two categories: The people he can trusts and the people he doesn't care for; a few examples of the first category would be Alpha, Elena, Sara and Shizuka.

However, while he does have a soft spot for those in the first category, and is shown to act more his age when around them, he's very neutral with people who're in the second category, holding neither a negative or positive opinion of them. In fact, he's rather indifferent, only attacks people who get in his way or deliberately approach him first.

While initially flustered by Alpha's advances, he is shown to grow used to it over the course of the web novel. He is shown to have little interest in the opposite gender as of now (and thus is naturally dense), and is more interested in eating food and taking baths than in girls, as he never had such luxuries for almost his entire life.

Background
Akira doesn't have any special backgound. Just like most residents of slum he doesn't have any relatives, doesn't know his birth date and real age, live on street and waiting for food destribution. Akira doesn't have any connection with slum gangs and choose way of Hunter.

Adaptability and Advanced Growth Rate
Akira's abilities with Alpha's support is considered by others as good as a first rate hunter's because of his almost godly shooting ability and intuition. It is true that he manages to get this result because of Alpha's support but it has been repeatedly implied by Alpha that Akira is growing at an abnormal rate and she has had to adjust his training plan several times in order to match the speed of Akira's growth. During their time compression test in which Akira needed to increase his focus to slow down his time perception, Alpha expected him to learn the skill after 6 months of continuous training but he managed to do it after a few days and to continuously use it after a week, although he was still not proficient and it taxed his mind heavily. This was also true during their CQC training in which Alpha didn't expect Akira to learn the basics quickly. When in a near death situation, Akira can increase his focus to the utmost limit in order to follow his opponent's moves while working in conjunction with Alpha's support.

Danger Perception
It has also been noted that due to his repeated bad luck and encounters with many dangerous situations like being ambushed by monster swarms and hunters alike, Akira developed a "sixth sense" of sorts due to which he can immediately feel if danger is approaching, something which only veteran hunters have, this ability was enhanced with the help of Alpha.

Survival Instinct
Akira's survival instinct is so strong that in extreme situations he is able to overexert his body's capabilities and achieve superhuman feats in order to defeat his opponent. His latest testament of strength was when he killed the real body of the Bounty Monster Overgrown Snake all by himself without the help of Alpha' s support. Such a feat is only accomplish-able by a team of 6 A-rank hunters.

Weapons and Equipment
In the starting of the manga and web novel, Akira is shown to carry a random handgun discovered on the ground.

AAH Rifle
This is shown to be Akira's primary weapon. It is an anti-monster automatic rifle. He uses two of these guns, and has equipped it with a scope for better visibility. While the gun is certainly useful against enemies with a weaker defense, and is cost-efficient, it fails to deal any damage against more tougher enemies.

CWH Anti-Material Rifle
This is Akira's secondary weapon. It is an anti-material rifle. It is far stronger than the AAH rifle, however, it is not capable of consecutive shots. It is shown to be very costly to mantain, and thus, Akira only uses it against very strong enemies. It easily tears through multiple enemies at once due to its high caliber.

Augmented Suit Keilon
Akira is shown to use this "greyish-black" suit for at least 41 chapters in the web novel. As described by Shizuka in the web novel,

'“It’s the TLT type C-style augmented suit. Its name is Keilon. It might be 2 generations behind the latest generation augmented suit, but its hardware is not that different compared to the current generation."'

The suit is shown to be flexible and designed for high mobility combat. Not only does it increase Akira's durability and strength, it also increases his speed and agility. In the starting, it was describe as too heavy for Akira to move on his own, and needed Alpha's support in order to move at all. After her training, Akira becomes considerably better at using the augmented suit.

Information Gathering Device
This device records everything around him, including the route that he takes, the type and number of monsters that he encounters, and how many of those monsters he has defeated. All of this data could be then exchanged for money at the hunter office. It also allows to detect monsters and store the information on different type of monsters.

Alpha
Akira first met Alpha in the Kugamayama city ruins as a weak, bruised and dirty orphan slum boy who wished to become a Hunter to make his life better. While he was hesitant at first, he eventually accepted her request and she became one of his greatest allies.

Akira is shown to have a great amount of trust in Alpha, and views her as an ally. At the same time, however, he is often insecure about his skills, that he depends on Alpha's support too much and is afraid of being weak.

He also often wonders and question's Alpha on what her goal is, however, even after being turned down, he does not find her suspicious, which shows his trust in her. He is not aware of the fact, or even entertains the possibility that Alpha might be manipulating him.

Shizuka
Shizuka is the shop owner of the store Akira is a regular to for weapons and other gear. In the starting, Shizuka was shown to be initially afraid that Akira would not survive long as a hunter, but as the story progressed she is shown to grow caring for him and become attached to him. Shizuka very caring for Akira's safety, and becomes angry at him when he puts himself in excessive danger.

For his part, Akira is quite attached to Shizuka, and will not hesitate to murder anyone who dares to threaten her, since he sees her as a friend (or even as an older sister), and always visits her store when purchasing armor and weapons, even if she does not have his desired item in stock; he trusts her to negotiate with third parties and allows her to choose his gear herself, putting faith in her ability to judge customers.

Elena & Sara
Akira met the poor and weakened duo in the wasteland as they were surrounded by enemy hunters. Akira had unintentionally saved them, by killing the enemy hunters off out of his own hatred; as Alpha explains it in the manga, "In other words, he didn't kill the men in order to save the girls. He saved the girls in order to kill the men."

Unaware of this, Elena and Sara were still very grateful to him, for saving their life and helping them get back on their feet again. Akira, however, felt guilty as his act of heroism wasn't genuine, and on this basis, his relationship with the two was built. He is shown to trust them as allies. They have often helped him in combat as senior hunters and lent him their older gear for use.

Over time Akira developed a certain attachment to them, even putting aside his tasks in order to help them. This relationship would be put to the test during the incident with Alna.

When Alpha generated a visual hologram of them naked, standing together, Akira was seen visibly flustered. Later, it is revealed that Akira is attracted to older women.

Sheryl
Sheryl met Akira after he had killed all of her ex-gang members. Later on, she builds up her own gang with his and Katsuragi's help.

She is shown to be very emotionally fragile, and thus, relies on Akira as her emotional support. At first, she tried to seduce him using her body as well, but was surprised by how disinterested he was.

Akira does not yet count her as an ally, and is shown to be rather uncomfortable when she hugs him, although he does allow it. He still sees her as no more than a business partner, and promised Katsuragi to kill her and drop her body off in the wasteland if she slowed him down.

As time went by, Akira began to develop some concern for Sheryl well-being, however, he still prefers to attend to his affairs, instead of helping her.

Carol
After narrowly escaping the old world ruin, Carol tried all means to seduce Akira, although without any success. Akira recognizes Carol's abilities, and so far, he only sees her as a simple acquaintance, to her disappointment.

Shikarabe
Shikarabe and Akira maintain a purely professional relationship. After working together on some missions, and witnessing Akira's abilities, Shikarabe developed great respect for Akira, but also recognized that something was wrong with him.

Katsuya
Akira has a complicated relationship with Katsuya. At first, Katsuya was simply envious of him for being close to Sara and Elena, however, after coming to know that he was after Alna's life, Katsuya developed a deep hatred for him. Akira is shown to get uncomfortable and irritable whenever he sees Katsuya, however, he still prefers to mind his own business than start a fight, unlike the former.

Reina
At first, Reina did not take Akira seriously, however after seeing his great power she began to change her mind quickly to the point of taking into account all the advice that Akira gives her. Reina has great admiration and respect for Akira, usually taking him as an example to follow.

Reina usually appreciates all the advice she receives from Akira by inviting him to eat at the best restaurants in town, which he really likes.
