History of manga
Military action-adventure stories set in the modern world, for example, about WWII, remained under suspicion of glorifying Japan’s Imperial history[98] and have not become a significant part of the shōnen manga repertoire.[98] Nonetheless, stories about fantasy or historical military adventure were not stigmatized, and manga about heroic warriors and martial artists have been extremely popular.[98] Some are serious dramas, like Sanpei Shirato's The Legend of Kamui and Rurouni Kenshin by Nobuhiro Watsuki, but others contain strongly humorous elements, like Akira Toriyama's Dragon Ball.
