Frankly, I know very little about seppuku. I know that Ranma would be 
forced to commit it if he had failed in becoming a man. Some people have 
said that the way I had him kill himself was a little anti-climactic, but 
I'm not sure how else to do it. I don't want to build to his "suicide". 
That doesn't seem quite "real" enough, I guess. I mean, how do you build 
up suspense to the death of your main character, especially if he wants 
it to happen, and nothing's gonna stop him? He felt he had failed, and so 
he handed his life over to his mother. I'd like to think that it's out of 
love that she killed him, but you can think what you'd like. :)
Anyway, whether it's more honorable or whatever, that's the way it 
happened. :)

Well, you should try to change it so that Ranma himself commits seppuku,
not that his mum just kills him. Go look up how it's done or something,
if you don't know... But basically, the person killing himself cuts open
his stomach, and then the second chops off his head (not chops his head
in half)...

Kun-chan...
