Here’s a fic I wrote last month for a secret Santa, it’s eldritch themed, mostly gen but pre-GrimmIchiHime.
Title: Stay a little longer in the sun
Characters: Grimmjow Jaegerjaques, Inoue Orihime, Kurosaki Ichigo
Tags: mentioned Nel and Harribel and Urahara, Mystery, Eldritch, dimensional shenanigans, human sacrificie (unsuccessful), kind of horror but it's pretty mild, unhinged late night worldbuilding, semi-graphic language, basically Grimmjow and his potty mouth, Secret Santa
Summary: Paranormal Detective Grimmjow Jaegerjaquez is in town for a simple job: help Kurosaki Orihime find her missing husband. But the small town of Karakura is hiding big secrets, ones that will soon boil over into a mess and pull Grimmjow back to the past he thought he’d put behind him.
