==== Author Corner ====
This is my first attempt of writing.
*this is not fully romance novel, it's just how an Inugami do their things.
I love Youkai and Ninja especially kunoichi so why not combine it together?.
Pardon my limited vocabulary.
The story will follow Naruto canon plot line with some added improvisation.
I love watching Youkai anime, my favorites are: Natsume Yuujinchou, Nurarhiyon no mago, Tokyo Raven, and Mushi-shi also the legendary Gegege no Kitaro, the story might take reference from those show.
Will add Glossary of mentioned Youkai on a chapter.
1chapter/week with around 1-2k words.
I have my own depiction and concept of Onmyouji so it might be different from other popular definition.
Cover is not mine if you want to take it down contact me, it's just how i describe the main character.
