If you like mystery and slice of life why not check out TLC?
The comic is about a young girl that gets kicked out of an orphanage for her unpredictable powers and ends up getting taken in by a shapeshifter into a mish-mashed adopted family. she has to learn what it means to be herself, be part of a family, and uncover whatever the family's butler is hiding before its too late!
The comic has got aspects of modern fantasy, mystery, found family, slice of life and LGBT themes (mostly i later chapters). I'd probably rate it at PG-13 (specific Pages with PG-13 content are flagged as such in the episode tittles as well)
Heres the link if interested!
