It is fairly well written.  Details are quite good.  But I don't think 
you grasp Ranma's personality.  Moreover I don't think the whole family 
could just stood there and do nothing.  Suicide is suicide, there is 
nothing honorable about it.  His mother did not even know 
his curse and therefore did not have a reason to force to commit sepukku.

Anyway, thanks for reading my jabber.
