Kazamatsuri, a modern, well-developed city renowned for its burgeoning greenery and rich Japanese culture, is home to Kotarou Tennouji, a high schooler least privy to the place's shared values. Content to fill his pockets with frivolity, the proud and nosey boy whiles away his time pestering the self-proclaimed delinquent Haruhiko, and indulging in his amorous feelings toward the oddball Kotori. Equipped with the superhuman ability to permanently rewrite any part of his body to multiply his strength or speed, Kotarou is naturally drawn to the supernatural. One special meeting with the lone member and president of the Occult Research Club, the Witch Akane Senri, leads to Kotarou reviving the Occult Club by recruiting Kotori and three other members: the clumsy transfer student Chihaya, the strict class representative Lucia, and the unassuming Shizuru. As Kotarou unveils hidden secrets of each member of the Occult Club through their shared adventures, he will inevitably encounter a fate that only he might be able to rewrite.

Shogi, a Japanese game similar to chess, is one of the most popular board games in the country, played by everyone from children to the elderly. Some players are talented enough to take the game to a professional level. The title of Ryuuou, meaning the dragon king, is only awarded to the person who reaches the pinnacle of competitive shogi. Yaichi Kuzuryuu has just become the youngest Ryuuou after winning the grand championship. However, the shogi community is unwelcoming to his victory, some even calling him the worst Ryuuou in history. Moreover, he forgets about the agreement he made with Ai Hinatsuru, a little girl he promised to coach if he won. After she shows up at his doorstep, he reluctantly agrees to uphold his promise and makes Ai his disciple. Together, they aim to improve and exceed the limits of their shogi prowess: Ai, to unlock her hidden talents; Yaichi, to prove to the world that he deserves his accomplishments.
