Seconded. The Bitter End is generally regarded as the ultimate RanmaDark Fic, ruthlessly and relentlessly extrapolating the causes and results of comedic slapstick behavior into and through a far more realistic world than the anime depicts. It is a monumental presence in Ranma fic, and has spawned a number of both sequels and parodies. It's also singlehandedly responsible for the widespread awareness of rage disorder — the story's explanation for Akane's tsundere behavior — among anime fandom.
