Fujita Kazuhiro, he is a Japanese popular manga artist who's mainly worked with Shogakukan. In Japan, manga artists rarely enter into exclusive contracts with publishers. So, Fujita has also worked with Kodan-sha, not just Shogakukan.
Fujita's representative work is "Ushio & Tora" which started in the end of 1990 and finished in 1996. Over 20years ago! It doesn't become fossil yet, however. Shogakukan still publishes the comics now (2018).
Why do they publish yet? The answer is that it makes the readers excited, thrilled and impressed deep. Or they have no reason to keep releasing.
The story begins when one of the two main characters Ushio meets a tough-looking monster Tora. Aotsuki Ushio is a Japanese jr. high school student boy. One day, he happens to slip down to the underground of the warehouse. There's something whispering "human...?" there in the dark. Ushio strains his eyes trying to find what it is.
Ushio finds a tough-looking monster thrusted by an old spear. It looks like the spear seals the monster. Junior, draw this spear. the monster says. But Ushio has no reason to obey. Through many scenes, he finally takes it off from the monster. Freedom comes to him? No, no, no. The spear doesn't give it to the monster. Thus, Ushio happens to spend his life with the weird spear and the nameless monster.
This is the first series by Fujita Kazuhiro. He said he put everything into "Ushio & Tora." It will teach you a lot through reading. Probably, it kind of contains his philosophy. Reading "Ushio & Tora" certainly makes you get what Fujita Kazuhiro is.
