Sukeban no me ni namida? Rûru muyou no kakutou shintaisou kecchaku - S1-E13
Plot hole: In the anime, Ranma commits an unsanctioned violation of the rules when she throws Kodachi out of the ring (the time when she gets saved from her schoolmates); she in fact grabs Kodachi's arms using legs and feet, and projects her. In the original manga there is no such mistake; Ranma used her feet to spin the club Kodachi was holding, so was not throwing Kodachi directly, but using the tool just as the rules say. (00:15:45)
