Hi there! Thank you for asking!
When I reopen requests, I’ll take requests for scenarios in addition to headcanons. I’ll do SFW and NSFW requests, but nothing involving non-consensual sexual situations between characters. Fights and violence are perfectly acceptable (I’ve written enough of that in my main fanfic). Since I’m currently just taking requests for Hellsing, I’d ask that for headcanons, please limit your request to one faction at a time (Hellsing, Iscariot, or Millennium). I’d also like to shamelessly plug my fanfiction and make it clear that I’m alright with taking requests about my OC too, for anyone that likes him.
These are more just guidelines, and open to changing, I’m still new to writing requests so I’m sort of coming up with my rules as I go along.
