The Iceblade Sorcerer Shall Rule the World manga volume 9 features story by Nana Mikoshiba and art by Norihito Sasaki.

Ray and his friends host their outrageous maid café at the Arnold Academy Culture Festival, but Rebecca is notably isolated from her peers. Her engagement to the much older Evan Bernstein brings dread instead of fairy tale dreams. Rebecca's sister Maria enlists Ray to stop the exploitative arranged marriage. Unbeknownst to them, there's another member of the Seven Great Sorcerers to aid in their cause. As more belligerents crawl out of the woodwork, can the Iceblade Sorcerer come to the rescue as the knight in shining armor?
