hi there.  I dont know much about Osamu Tezuka.  Could you tell e about it?
He started the manga revolution in Japan with his piece 'New Treasure Island' in 1947.
oh that is super interesting!  did he do any other pieces?
Of course! The Manga series had 'Astro Boy', 'Jungle Emporer Leo', 'Pheonix' and 'Black Jack'!
oh that is super cool!  I had no idea one guy was behind all that!
He sure was! Unfortunately he succumbed to stomach cancer in 1989. Very sad! 
oh that is! think of all the other things he could have done!
Yes, thats exactly why the Japanese public was absolutely devastated by his death, it was an abrupt and immediate impact on them!
