Methinks you have trouble understanding your own words. Specifically: Influence.

No, I understand the word perfectly.

It's perfectly possible - quite common, in fact - to be influenced by someone and NOT be in the same style as them. Especially once you get 10 and 20 generations removed from the initial influence, and are picking up the the 'influence' through the filters of other artists.

If something has an effect on the condition or development of something else, then that can be held under Style.

Can. Doesn't have to.

Look at your own chosen definition of influence:

to have an effect on the condition or development of.

'To have an effect'. Not to control. Not to define. To have an effect.

'Style' isn't a cladistic word, where 'style' remains constant through all descendants - it's a descriptive word, it describes the work - taking influence from someone who came before doesn't make you the same style.

In fact, taking it as cladistic renders it utterly useless, especially in a community as syncretic as the manga community - or to revive the analogy, rock 'n' roll.

If you are the same style as your influences, once you've got more than one tradition playing into your influences - which even Tezuka himself did - your style suddenly becomes a mass of hyphens, and even less possible to argue as 'the same' as someone else's, because they'll have a different mass of hyphens.

Tezuka's influence is felt throughout the manga community, even those who've deliberately rejected it, but they're also influenced by western artists who came after Tezuka, traditional Japanese, Chinese, or western art, the manga artists who came between Tezuka and themselves (who, themselves, have other influences, etc)... Each one having their own different set of influences, and personal innovations.

the Rock'n Roll Hall of Fame

...acknowledges Rock's syncretic roots, so I rather doubt any display they've had claims that everyone who plays under the rock umbrella is the same style, any more than it claims they're all blues musicians, or gospel singers, or to use more recent influences, those that have been inspired by the Beatles are traditional Indian musicians, etc...
