The light novels are being translated into traditional Chinese and the first volume was published and released by Sharp Point Press on November 9, 2010. The Chinese translations of the light novels were originally under an indefinite suspension.

Yumizuru had also stated that he was willing to fight over this matter in court if necessary.
