Sora (No Game, No Life)

Sora is the main male protagonist of the No Game No Life series and the cunning and manipulative half of the siblings.

Abandoned by his parents, Sora is a brilliant NEET (Not in Education, Employment, or Training) hikikomori (shut-in) gamer along with his step-sister, Shiro, with whom he forms or Blank with. Having gone through a rough childhood, he has a lackadaisical hate towards life and pretty much dedicates himself only to gaming. One day, both him and his sister is called into an alternate world after they defeat Tet in an online chess game. Sora's biological father (no relation to Shiro) married Shiro's biological mother (no relation to Sora), thus, making Shiro and Sora step-siblings.

Appearance
Sora is a tall and lean young man with smooth fair skin, spiky black hair in the light novel (maroon in the anime). He has red eyes with dark bags under them most likely due to excessive gaming with little to no 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 with the text "I (heart) humanity" in Kanji, along with a blue undershirt with a red hand band and sneakers. He wears his crown on his left arm.

Personality
Despite being a NEET and shut-in, Sora is extremely outgoing, confident, with endless vitality and virility, not afraid to play with people face to face, even when they are cheating. He's extremely manipulative, which he calls "negotiation and diplomacy skill". This compliments the playing style of Shiro consisting of logic and calculations, while his consist of emotions, observations, deductions, behavior, language, tactics and human logic. He can be extremely arrogant and speak in a condescending manner with those he plays against, especially AFTER discovering a winning method.

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 looks 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 crash the first they arrived in the world of Disboard.

While he is typically calm when playing games, he can sometimes be very nervous when not knowing what to do. This is depicted when he was battling Chlammy, during the battle he displays a calm personality but is in fact, panicking. When Shiro holds his hand he regains his confidence. He also seems to be a bit of a misanthrope as he claims humans are stupid, lowly creatures, including himself. However, he believes in the potential of humanity as demonstrated by Shiro, a person who has hope and fantasies. He also believes that living in the world that he was born in was a mistake (when Tetspeculates about a world with Disboard's rules), that he was supposed to be born in another world, with his sister Shiro.

Despite being arrogant, manipulative and cunning, he loves his sister dearly (to the point where they can't be separated). He cares for the people who become either his friends or allies as the series progressed, this is shown when he felt guilty for insulting Steph's grandfather (which made her cry) and angrily berates Azriel for even calling herself Jibril's sister because the latter had bet her life on their game for her.

Abilities
Despite being a shut-in, Sora has incredible superhuman charisma and eloquence. He is an excellent and natural speaker, always knowing exactly what to say to get others on his side. He has no problems dealing with people or groups, after overcoming the initial shock.

While not as intelligent as Shiro in calculations, he is shown to have a brilliant super-genius IQ and an eidetic memory which enables him to quickly learn, understand, and easily recall limitless amounts of information perfectly and rapidly. This is demonstrated during his card game with Stephanie. Rather than computing numbers like Shiro, Sora can quickly determine what his opponents are going to do based on observation of their behavior and motivations, a technique called "cold reading". His amazing observational and deductive skills help him come up with complex plans quickly and efficiently. This is shown during his game against Jibril and when he figured out the previous King's plan to beat the Werebeast. He was even able to learn to read Imanity-go (language) in just about one hour slower than his sister (self-proclaimed).

He is also highly manipulative (convincing an Inn-keeper to let them stay four nights) despite not lying to others (although he does tell half-truths), along with showing proficiency at strategy and romance games. His superhuman charisma, eloquence, intelligence, memory, tactical/inventive skills, and his ability to rule, allows him to quickly fix all of Elchea's problems from economics to agriculture within a few weeks of being crowned King (with the help of the thousands of ebooks on his tablet).

Weaknesses
While brilliant, Sora is not nearly as intelligent as his sister when it comes to calculative based games and through his own admission, can't play games such as a match of chess against a high level AI as effectively. Despite being a shut-in, he is 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 elicits a scolding from Shiro. He also has trouble with crowds but is shown to be able to can handle them when he is with his sister.

His most significant weakness is his reliance on Shiro. If he is separated from her by so much as a door, he becomes a quivering, spineless coward. During episode 11, he was able to overcome this completely as they were holding hands in the real world while in their game pods.

Trivia

 * The kanji for (Sora) means sky in Japanese, but can also be read as (Kara) which means emptiness, as pointed out by Shiro in during 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 in Japanese means none. It can also be interpreted as a joke, because when combined with their first name, Nai Sora means "not empty" or "not Sora."
