Summary
Sometimes you have to kill a few demons before you can find the bravery for a love confession.
Or, alternatively, you and Genya get more than you bargained for when you face down a member of the Twelve Kizuki. Some blood demon arts are fucking weird, and this one is no exception.

Summary
Varang has taken to watching you. A lot.
It feels… challenging. Or appraising, maybe.
You avoid her to the best of your ability. You can’t look at her without thinking of the way she and Quaritch have gotten so much closer recently. They spend most of the day together; ostensibly talking strategy, but you see the way their touches linger. Even the way they look at each other like they’re the only two people in the world, as though everything else is just background noise.
But as the days pass, you realise something. When she’s not watching Quaritch with those bright, lamp-like eyes, she’s watching you.

Is there ever a day when Makoodles isn't cooking us a three course, five star meal? No. So go read their Avatar fics this instant if you're seeing this.

Summary
Two bodies consumed by loneliness; a shared coffin with the same emaciated maggots. When your life is reduced to decay leaching your blood, how desperate does that make a person?
~~~
Your decrepit house confines you with a gun & guests you don’t want. What should’ve been just an inconvenience turns sideways when you kill a dangerous Visitor. An easy job, typically… but it leaves your life - if you can even call it that - as stained as the blood on your living room carpet. The feelings turn out impossible to manage, & even more so when you find a freezing stranger next to where you sleep.Bookmarked by Katonyx

I didn't know that NINH had a whole ass fandom and I am so happy I found it, because this fic scratched such an itch.
Well written, felt super in character despite having limited source material, and I just ate this whole thing up in one sitting.

Bookmarker's Notes
If you're someone who is into the reader-insert genre and happens to also adore Verso, this would be the first fic I'd recommend to you.
I love what the author does with all of the characters and, though I'm not usually a personal fan of AUs, I adore this one. It feels very true to the original story while also diverging in a way that remains believable and reminiscent of the source material. I ran through this entire work in a day and was loath to put it down when I needed to actually get work done because all I wanted was to keep reading.
Super lovely balance of initial slow burn, mystery, soft romantic scenes, suggestive scenes, smut, and story. Definitely a new fan favorite for me.

Man.
Maaaaan, I fucking love spirk.
I read this one back in the day when I was first figuring out what shipping even was after seeing the chemistry in the reboot movies. Finding it again was like finding literal gold. To this day, still one of my favorite spirk fics and the one I think of whenever the ship is mentioned.

Dead dove, do not eat. Tags are what you get and I fucking looooove this one. Not always a huge fan of noncon or such dark themes but god do I love the Gyutaro characterization and the reader personality/POV here.
