This is really good! Though my fave is Sess x Kag pairing, I recently found that I like Touga x Kag too. Touga's like what you get from throwing in Sess and Yash in a blender with a big dollop of maturity - you get the power, sexiness, expressiveness and maturity...too bad there aren't many such pairings. While I like the few stories I've seen where Touga tends to be more mature, I also like that yours is different with a younger Touga though I wonder how that's going to turn out. Seems like there's a lot more youkais, segregation and discrimination in this era...hopefully Kag makes some other friends and it all turns out well.
I was hesitant to read this at first since it was Incomplete and there were only 8 chapters since 2011 but it sounded interesting and given there are not many Touga x Kag stories, gave it a go. I'm glad I did.
I really hope you update this story and see it through to the end. Thanks for sharing!
