Slow to take off, "manga" comics have finally hit it big in Britain and are now the fastest-growing sector in the publishing industry here.

Many young Brits who think Japan is cool have been drawn to manga through animation films, computer games and toys just as in other countries. However, Japanese comics still did not catch on in the U.K. as quickly as in the United States, France and Germany.

Experts say one reason is Britain does not have a tradition of adult comics, so there is perception that they are not challenging enough.
