I recommend the two novels, Conan's Violent Sorrow and Ke Xue's Silver Bullet, to you. The former described the story of a maxed out man who couldn't find his home in the world of Conan, while the latter depicted the exciting adventure story of the famous detective Fujiwara in the world of science. These two novels both have Haigahara in them. You will definitely like them. I hope you like my recommendation. Thank you.
