There is no H in the Battle Through the Heavens manga. Will it draw Xiao Yan and Medusa at the back?

My answer may confuse you. As a person who loves reading novels, I can't judge whether the manga contains the H element because this requires consideration of different authors and works. Moreover, the novel Battle Through the Heavens itself did not explicitly state whether the manga contained H elements. The manga was usually created by the mangaka according to his own creativity and style. He might add some H elements or plot that was different from the novel. Therefore, if you are worried about the H element in the manga, I suggest you ask the manga author or the copyright owner to ensure that your rights are protected. As for whether he would draw Xiao Yan and Medusa, it would depend on the manga author's creative plan and inspiration. At present, the specific plot of the Battle Through the Heavens manga has not been clearly revealed, so we have no way of knowing if the subsequent creations will include the plot of Xiao Yan and Medusa.
