Rewrite: SIDE-B

Kazamatsuri, a modern, well-developed city renowned for its burgeoning greenery and rich Japanese culture, is home to a boy named, Kotarou Tennouji, a frivolous and nosey high schooler . Kotarou spends his days joking with his childhood friend Kotori and pranking his rival Yoshino, all the while seeking greater contentment and connections in his life. In truth, he holds a secret- the superhuman ability to permanently rewrite his physiology, which lets him modify his strength and speed to his liking. With such traits, Kotarou is naturally drawn to the supernatural, and is led to meet the president of the Occult Research Club, the “Witch” Akane Senri. This 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 kohai 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. Rewrite:Side-B and Rewrite:Side-R are meant to be read as a pair. One follows the route where Kotarou picks the “Self” choice, the other follows the “World” choice. It is recommended to read the VN for greater context.
