Back at it again, this time with all the Onmyoji novels series based manga I'm aware of! You can purchase all of these from Bookwalker without needing to be in Japan as for as I'm aware, but your experience may vary. Note that none have official English translations as of 2023.
Reiko Okano's Onmyoji
This series is apparently the manga adaptation for Onmyoji - it won the Tezuka Osamu Cultural Grand Prize (yes, that Osamu Tezuka) in 2001 and the Seiun award (think Japan only Hugo awards) for best comic in 2006. I haven't read much of it unfortunately (I can't afford to buy all the volumes!) It has 13 volumes and a sequel (where you get to see Seimei's son!!!) A few volumes of this manga have been translated in French, but I haven't been able to get my hands on a copy :(
Mitsuki Munku's Takiyashahime
A mostly straightforward adaptation of the two-part novel series Takiyashahime. If you can't read the novels, you can read this and get a rough idea of what's going on if you can't read much Japanese (or watch the drama special I mentioned in this post!)
Itou Sei's Takiyashahime aka 瀧夜叉姫 陰陽師絵草子
(Takiyashahime Onmyoji Ezoshi)
Okay okay SO THIS MANGA. It adapts Takiyashahime, but puts its own spin on the characters. Seimei is now Haruaki (which is just the kun'yomi reading of 晴明 - Seimei is the on'yomi reading. I could talk about nanori and azana more but that's for a separate post), a young, talented onmyoji who is nonetheless still a mere apprentice. He's a lot more hot-headed and kitsune-like, but also a lot more insecure with being friends with Hiromasa due to his social status. Yasunori also plays a larger role in this as Haruaki's main mentor/shishou instead of senior disciple, probably because the author had a previous manga that involved him as a character (unrelated to the Onmyoji series) I have MANY words about the flavour of Seimei/Hiromasa in this, but it's hard to explain without context!!!
This manga has absolutely GORGEOUS art - beautiful lineart, dynamic panelling, and lovely watercolour splash pages. However, it does not shy away from graphic violence, with multiple instances of animal death, human death (including children) and one instance of graphic sexual assault (which is in volume 3, pages 109-111, if you would like to skip it) It is currently ongoing as of 2023, and you can follow it here.
Top notes: This came about from 2 different writing prompts which then turned into two different stories. But both are connected with the same character: Mungojerrie.
I don’t write a lot of stories using this character and I thought it would be a great idea to also include two headcanons I have. However, this also meant that there will be another fic connecting those ideas.
In this story, Mungojerrie and Rumpleteazer had only been with the Jellicles for a few months. While Rumpleteazer isn’t in this story physically, she is an important part of Mungojerrie’s character and internal struggle. She is the sole reason Mungojerrie wants to do this.
Summary: Mungojerrie was nervous but with a sort of nervousness that came with uncertainty. He was about to ask Munkustrap an important question. He’d only been with the Jellicles for a short time yet he knew this was something he needed. If not for himself then for Rumpleteazer. Someone he needed to protect.
Original Prompt: Teach me to fight!
Characters: Mungojerrie, Munkustrap, Macavity (mentioned), Rumpleteazer (mentioned)
Warnings: Trauma, self-doubt
Follows the headcanon that Mungojerrie used to be one of Macavity's henchcats and did anything to protect Rumpleteazer. They have only been Jellicles for a few months.
Bottom Notes: Thanks for reading! I am writing another fic where Mungojerrie meets Skimbleshanks that is mentioned in this story. I can't wait to finish it too.
