The year is 2325. Through mathematical discoveries, magic has been unlocked in the world.

Scribe, Socket, Tierce, and Wilde are a group of friends working to protect a newcomer Clover, a shape-shifter escaping a magical organization known as the Inferno Guard.

The Society of Sourcerors, the world leaders of magic, are divided. A group of radicalists, determined to launch a new global government, must be stopped.

Supported by the staff at the Library of Equations, the friends must use their cunning, intellect, and ability to solve new magical equations and gain the advantage over the Society of Sourcerors – all while Socket and his friends continue searching for his missing little brother, Damien, and while Scribe navigates the waters of a new relationship with Lianna, who introduces everyone to exciting and dangerous discoveries.
