Sora

One of the main protagonists of the series. He is 18 years old at the start of the story and turns 19 in volume 12, marking one year since being summoned to Disboard. He is unemployed, a virgin, unpopular, has communication issues, is a gaming addict, and is Shiro's stepbrother (his father remarried and Shiro is his stepsister).

In games, his role is in the humanities. He excels in areas involving people (entities with will) such as history, society, economics, politics, and law (rules). Therefore, he uses game theory, rhetoric, and other techniques to deceive his opponents and achieve victory. However, he never lies to himself. Lacking innate talent (strength), he has honed his skills to drag his opponents down to his level (the bottom) and win.

He is extremely skilled at detecting "uncertain elements" such as bargaining, reading minds, and psychological manipulation, and his exceptional foresight is almost akin to future prediction. Additionally, he has the insight to see through any cheating by his opponents and excels at cold reading. However, he dislikes incomplete victories or games that his opponents cannot enjoy.

Despite his ability to read others' thoughts, he is very insensitive when it comes to romance, having remained a virgin for 18 years. He believes that humanity, including himself, is incompetent, but meeting Shiro has made him believe in the potential for "genius" within humanity.

He cannot be separated from Shiro and is exploring the boundary between all-ages and adult content as both a hobby and a practical pursuit. Although he is a virgin, he has a daughter created by the queen of the sea-dwelling species using his hair without his consent.

In the "This Light Novel is Amazing!" male character rankings, he placed 6th in both the 2015 and 2016 editions, 9th in the 2017 edition, and 6th in the 2018 edition.
