Chûgoku kara kita aitsu! Chotto hen!! - S1-E1
Continuity mistake: When Genma roars at the crowd, everyone's umbrella is gone. They already went from open at the beginning, to closed, as if it stopped raining in the span of 5 seconds. (00:03:30)
Ranma to Ranma? Gokai ga tomaranai - S1-E4
Continuity mistake: The shape and order of the 5 pictures laid on the table by Nabiki differ entirely from the POV close-up of Kuno. That happens also with the shots of Akane. (00:12:50)
Asobi ja nainoyo gakkou wa - S1-E2
Continuity mistake: When Tatewaki Kuno shows up, the clock tower shows 8:35, when the clock was shown advancing from 30 to 31 when Akane finished the last opponent a moment earlier. (00:10:35)
Ranma to Ranma? Gokai ga tomaranai - S1-E4
Continuity mistake: Kuno tosses the doll to Ranma; he catches it in horizontal position, but is holding it by the waist in the following shot while Kuno is still mid-sentence. (00:15:45)
Hone made aishite? Akane koi o fukuzatsu kossetsu - S1-E5
Continuity mistake: When Akane bares Ranma's chest against the outer wall, the crowd behind her varies throughout the scene (for instance the fencer pops up out of the blue). (00:14:40)
Asobi ja nainoyo gakkou wa - S1-E2
Continuity mistake: The polo shirt of the guy leaning unconscious against the school gate is pale violet for the greater part of the scene, but orange when Panda rushes in. (00:14:15 - 00:15:20)
Asobi ja nainoyo gakkou wa - S1-E2
Continuity mistake: When Genma wins a bout of midair kicks and knocks him into the pond, the table is empty in the wide shot, while breakfast is ready when Kasumi speaks. (00:02:55)
Ranma to Ranma? Gokai ga tomaranai - S1-E4
Continuity mistake: Female Ranma had a shoulderstrap of her tanktop down in a sexy way - once Nabiki turns her back into the male form, his shoulderstrap is back up. (00:09:10)
Ikinari ai no arashi chotto matteyo - S1-E3
Other mistake: At the beginning of Akane's run through the horny guys at the school entrance, the clock on the tower is missing the hour hand. (00:16:00)
Hone made aishite? Akane koi o fukuzatsu kossetsu - S1-E5
Continuity mistake: At Tofu's, Akane puts a hand on Ranma's mouth; the hand is initally the right, but in the wider shot it becomes the left. (00:21:10)
Ikinari ai no arashi chotto matteyo - S1-E3
Continuity mistake: In the scene with Ranma drying her clothes on the tree, the teapot changes orientation several times between shots. (00:06:30)
Akane no shitsuren datte shouganai janai - S1-E6
Continuity mistake: Genma's magazine looks entirely different in the close-up compared to how it looked as he was reading it. (00:17:50)
Chûgoku kara kita aitsu! Chotto hen!! - S1-E1
Continuity mistake: The water stains on Genma's gi when Soun turns him back into human form changes between shots. (00:18:40)
Chûgoku kara kita aitsu! Chotto hen!! - S1-E1
Other mistake: When Ranma is battling Genma at the very beginning, she slides into the main road. Behind her is a vending machine for drinks, only, it's marked "DOLINK" (bad transliteration). (00:03:00)
Shanpû no hangeki! Hissatsu shiatsuken wa mimo kokomo ubau - S1-E16
Other mistake: Akane wakes up with the sun already up and getting ready to go to school...when her alarm clock shows it's 5:25. (00:02:00)
Onna no koi wa snesouyo! Kakutou shintaisou de iza shoubu - S1-E12
Other mistake: When Akane and Ranma arrive to Furinkan High, it's 8 past 20. When Kodachi leaves, it's 8:35. 15 minutes is way too long of a time to have passed (and everyone would also be late for lesson). (00:01:50 - 00:04:40)
Hone made aishite? Akane koi o fukuzatsu kossetsu - S1-E5
Continuity mistake: When Ranma walks back to toss Genma into the pond, the kettle he drank from earlier has disappeared from the table. (00:02:45)
