Sora

Sora is the primary male protagonist and the trickier and more intelligent half of the brothers in the No Game No Life series. Sora is a gifted NEET (Not in Education, Employment, or Training) hikikomori (shut-in) gamer abandoned by his parents.

Hikikomori by nature, Sora likes to hang out with his step-sister Shiro, the other half of Blank, inside. Sora excels at diplomacy and negotiation, which help him in his gaming ventures. He and Shiro, his stepsister, make up the group Blank.

Despite being a NEET and a recluse, Sora is incredibly extroverted, self-assured, and virulent. He isn't scared to play with people in person, even when they lie or cheat. He refers to his prodigious capacity for deceit as a "negotiation and diplomacy skill" and is quite cunning.

Shiro's playing style is based on calculations and logic, unlike Sora's, which is based on emotions, perceptions, inferences, behavior, language, tactics, and human logic. He can be very arrogant and speak to his opponents in an insulting way when he plays against them, especially after developing a winning plan.

Being incredibly intelligent, Sora and Shiro frequently complement one another's strengths in the No Game No Life series. As the King and Queen of the Commonwealth of Elkia, Shiro, and Sora further show their power of strategy. Shiro and Sora are master strategists, devising plans to counter every adversary that tries to strike Elkia.
