The cat woke me up at 5:30 and I was too awake to go back to sleep, and just lying there with all my worries going through my head wasn't working for me, so I got up and watched episode #2 of Mushishi. This one follows chapter #3, I believe, of the manga - the River of Light episode.
A second entry immediately after I posted the last one, to spare anyone who doesn't want to read the spoiler in the previous. Give me examples of manga/manhwa/manhua based on fiction or history, plzkthx. :) Loosely based is OK. The ones I can think of offhand are:
CLAMP, RG Veda, the Rg Veda Kazuya Minekura Saiyuki, Saiyuki Reload, the Journey to the West Akira Toriyama, Dragonball, Dragonball Z, ditto You Higiri, Cantarella, the life of Cesare Borgia Nobuhiro Watsuki, Rurouni Kenshin, looooooooosely based on the events and personages of the Meiji era Han Seung Hee and Jeon Jin Seok, One Thousand and One Nights, which is a double whammy being based on the Arabian Nights for the containing story, and gleefully ripping off world literature and history for the stories within the story Takehiro Inoue, Vagabond, based on a historical novel about the youth of the historical figure Musashi Miyamoto
I'm not really talking light novels turned into manga, like Slayers, instead more of a fanfic approach like One Thousand and One Nights, or taking an older, traditional story and retelling it reasonably accurately (I have no idea how close to the source CLAMP's RG Veda is) approaching it from a different direction, like Saiyuki. (Vagabond is a bit weird, but I'm under the impression it was a classic novel before being adapted, and wasn't written with eventual manga/anime in mind.)
