So what do we know of the pattern of inheriting skills from members of the same shinigami family so far? 1. Ichigo's zanpakuto (whatever it ends up being) bears a name similar to his father's, and he and Isshin are using the same technique - Getsuga Tenshou; 2. Kuchiki Ginrei's sealed zanpakutou looks similar to Kuchiki Byakuya's.
I am sure there must be more than what I have here that you guys have spotted, that would throw some light on Bleach skill heredity. Any other shinigami families whose similar skills we are aware of (leaving aside the fact I can't really imagine what it means to be 'born' into a family in Soul Society where people go when they die :))?
Also, going the other way around, can we say that shinigami with similar type zanpakutou are somehow of similar character?
I would love to hear your thoughts.
