水木しげる
Just like Gekiga, horror manga started to appear in the lending libraries (Kashihonya) of the late 1950s and early 1960s and expanded into the mainstream through the works of artists like Shigeru Mizuki ("GeGeGe no Kitaro"), Jirō Tsunoda ("Kyōfu Shimbun"), Kazuo Umezu ("The Drifting Classroom") and Shin'ichi Koga ("Eko Eko Azarak"). While most of them published in shōnen magazines and often with scary, yet sympathetic protagonists leading through tales about ghosts and demons, Umezu for instance got his start in shōjo magazines, where psychological depth was the main focus, a famous title being "Hebi Shōjo".
