X (manga)
Ohkawa cites Go Nagai's "Devilman" as a stylistic and thematic influence. Beyond his penchant for drawing extreme violence, Nagai's writing involves themes like the nature of good and evil and fear, ideas that left an impression on Clamp's writer at an early age. Like "Devilman", "X" follows two male best friends destined to fight each other on Armageddon, a confrontation brought about by the murder of the hero's childhood sweetheart. The rest of the cast includes characters from the group's entire canon, including unpublished works, effectively creating a whole world inhabited by their creations. The ensemble cast, inspired on Kyokutei Bakin's "Nansō Satomi Hakkenden", includes Subaru Sumeragi and Seishiro Sakurazuka from "Tokyo Babylon" and the main characters of "Clamp School Detectives".
