if you're willing to classpect anime people... Allen, Lenalee, and Kanda from D Gray-man? and maybe the Earl if that's not too hard?

Oof these may be a bit more difficult, I can’t remember much about D.Gray-Man, I’m due for a re-read some time. Specially recently given there’s some really huge reveals about some of the characters later on that add a layer on top of what the beginning presents, maybe in a few months I can properly answer this one.
