Thinking about making a few official self-insert original characters to write longer stories with them. Fair warning that a lot of them may be psychics of some kind.
Ghost: nickname/alias for the medium self insert trained in psychology and behavioral analysis. Her abilities and skill-set are inspired by Melinda Gordon from Ghost Whisperer or Alison DuBois from Medium. She started solving crimes on her own (with help from deceased victims and her training in profiling) by anonymously sending in information until she met L.
Free/Ever/Eden: Wammy alias/new name for the self insert with psychic powers similar to Cody Morgan from Before I Wake. She will most likely be a longtime friend of L’s who lives at Wammy’s house with him as she struggled to control her dangerous ability.
Jinx: nickname/alias for the self insert with psychic powers along the lines of Matilda or Carrie from the films of the respective same names. Unclear how she met L.
Meera/Clarity: nickname/alias for the self insert with psychic powers like Alice Cullen, except she can also intentionally trigger visions by handling certain objects or going to certain locations.
