Sora

Abandoned by his parents, Sora (空) is a brilliant NEET (Not in Education, Employment, or Training) hikikomori (shut-in) gamer along with his step-sister, Shiro which formed 『　　』. He does not take life very seriously and is pretty much a good for nothing gamer. One day, he and his sister are called into an alternate world after they defeated Tet in chess. He is the main male protagonist of No Game, No Life.

Appearance
Sora is a tall and thin person with spiky black hair in the light novel and maroon in the anime, also donning red eyes with dark bags under them which are probably due to excessive gaming with no signs of rest (sleep deprivation) and constantly wears a sly grin on his face. He was also seen in the old King's clothing and his yellow shirt which has the text "I (heart) humans" in Japanese.

Personality
Despite being a NEET and a shut-in, Sora is extremely outgoing and confident, and is not afraid to play games with people face to face, even when they're cheating. He is also extremely manipulative, what he calls "negotiating skills". This fits into his play style, as Shiro is excellent with logic and computing, Sora can read people using a technique called "cold reading" and predict what their next move is, using the knowledge he quickly obtained to beat them. However, if he is separated from Shiro by so much as a closed door he becomes a spineless, cowardly wreck, and only returns to his former self if he is able to see or hear her. He views his sister as his equal and partner and even looking up to her, but is also protective of her, such as putting his body between her and the ground when he thought they were going to hit hard when first arriving in the world of Disboard.

Strengths
Despite being a shut-in, Sora is an extrovert and has no problems dealing with people. While not as intelligent as Shiro, he is shown to have a brilliant IQ. Rather than computing numbers like Shiro, Sora can quickly determine what his opponents are going to do based on observing their behaviour and motivations. He was even able to learn to read Imanity-go in just about one hour slower than his sister (self-claimed). He is also highly manipulative, convincing an Inn-keeper to let them stay four nights. He is also good at war and romance games.

Weaknesses
While brilliant, Sora is not as smart as his sister, and through his own admission can't play games like high level chess games effectively. Also despite being a shut-in, he is also slightly perverted, and desires a girlfriend for himself, with his lust leading to a linguistic mistake that causes Stephanie to fall in love with him, and causes him to receive a scolding from Shiro. He also has trouble with crowds, but can handle them when he is with his sister. Finally, his biggest weakness is his reliance on Shiro. If he is accidentally separated from her by so much as a door, he becomes a quivering, spineless coward. However, during episode 11, he was able to bypass this completely.

Character
Sora is 18 years old. He later becomes king after winning a game and therefore his sister becomes queen.

He lives with his step-sister Shiro, and was abandoned by his parents at a young age. After that Sora pledged to be there for his sister no matter what.

Sora cares about his step-sister Shiro very much, and like her has a sibling-complex, being with her at all time and panicking if they're not in the same room together. His sibling-complex toward his sister doesn't keep him from hitting on other girls (mostly Stephanie Dola).

Background
In the light novel, Sora's family isn't being explained well. But there are parts from Shiro's point of view which tell about their parents. Sora and Shiro are step-siblings, which means Sora's father married Shiro's mother. After the wedding, his family lived together, and that's when he met Shiro. At the time, Shiro mumbled ".....Really......how empty......," when she saw him smiling when people smiled ; A smile that contained nothingness and lacked expression. He was shocked at hearing that comment, then like he was found something big, he smiled and then asked her to play game with him. That day, they played 20 games in a row. As time elapsed, the siblings began to live together. Those that were called their parents were no longer present. He mouthed out such words to his little sister in reply,"Meh, from now on, it's just you and me then." From that point onwards, with their names joined together, they started to play online games. Conjoining the two names, 『 』was created. One after another, He kept coming up with strange, adaptable strategies that even she herself could not imagine. But then, the precise and accurate deductions that Shiro calculated out had far exceeded the expectations of Sora. At that time, the siblings started to play games as a Two in One. With an unbroken streak of victories, the two of them even came to be regarded as an urban legend on the Internet. When they defeated the self-proclaimed One True God on Internet chess, they were thrown into another world. This was a world where everything was determined by games, restrained by a force known as the Ten Oaths—— the world called Disboard.

Quotes
"Meh, from now on, it's just you and me then."

- Sora to Shiro

"This is what your grandfather believed in...Your grandfather was right to believe in Imanity. Now no one will call him a fool."

- Sora to Steph

"They say people can change, but is that really true? If they decide they want to fly, will they grow wings? I don’t think so. You don’t change yourself. You change how you do things. You have to make your own way. You have to create a way to fly, even while you stay the same."

- Sora to Shiro

Trivia

 * The kanji for 空 (Sora) means sky in Japanese, but can also be read as 空 (Kara) which means emptiness, as pointed out by Shiro in their first encounter.
 * Sora and Shiro's surname was said to be "Nai" by the author. This can be interpreted that their surname is literally Nai or that they have no surname, as Nai (ない) in Japanese means none. It can also be interpreted as a joke, because when combined with their first name, Nai Sora (ない空) means "not empty" or "not Sora".
