Someone asked about Ranma's history before his arrival at the
Tendo Dojo, what follows is information gleaned from the Ranma
1/2 Memorial Book.
The book gives no specific dates and since I know very little
Kanji so I am going by the illustrations. The year numbers are
written with Arabic numerals and take as a starting point that
he arrived at the Tendo Dojo at the age of 16 and only covers
events in the manga.
More than 10 years ago:
- Genma left with Ranma and signed the promise to make Ranma
a 'man among men'
10 years ago:
- Ranma meets and befriends Ukyo
- Ukyo makes her special sauce which Ranma ruins
- Ranma loses the Tendo Dojo to the Gambling King and signs a
promissary note to hand it over
- Ukyou's father and Genma make the engagement followed by Ranma
and Genma leaving with the Yatai
9 years ago:
- last known incident of Ranma's bedwetting. The book has that
picture of Ranma (nekkid) crying by a futon strung up to
dry. This picture was just shown in the Viz translations
when Ranma was learning the Hiryu Shoten Ha.
6 years ago:
- Ranma undergoes Neko-ken 'training'. The Viz translation has
Genma stating that Ranma was 'trained' in this technique when
he was 10 years old.
Within the last year:
- Ranma starts the bread feud with Ryoga
- Ranma leaves for China after waiting 3 days for Ryoga to show
up for their duel
- Ranma gets cursed at Jusenkyo
- Ranma knocks Ryoga into the Spring of Drowned Black Piglet
- Ranma eats the Dragon Hair
- Ranma defeats Shampoo who then chases Ranma and Genma after bestowing
the 'Kiss of Death'
The timeline ends there. Also Genma stated in the manga that they
were cursed only 2 weeks before arriving at the Tendo Dojo.
I know that these things are all already known but that is all
that has established in the manga of Ranma's history.
As a bonus the Memorial Book also includes a timeline of a typical
day for Ranma.
6:30am - wake up
6:45am - finished training with Genma over pond
7:00am - finished breakfast and leaves for Funrinkan
7:30am - on the road to school
8:30am - start of school
9:30am - gym/PE class
11:00am - eating in class
12:00nn - lunch period
2:00pm - cutting class to buy snacks
3:00pm - out of school and eating at Ucchan's
11:00pm - in bed asleep
Again this all that the book states and as with the events before
Ranma arrived at the Tendos leaves a lot of flexibility for
Takahashi or you fanfic writers to fill in the blanks.
