If Harry Potter were an anime

Below them: Should be younger Sirius Black or R.A.B and Kreacher.

Below: Professor McGonagall, possibly Umbridge next to her, Hagrid, Dobby- Luna's there too, can't recognize the other two.

Directly below that: I'm guessing younger Lupin and Cedric- no, can't be, Cedric has gray eyes if I remember correctly. The couple there's Lily and James Potter for sure and it's made obvious by the appearance of the Resurrection Stone.
Bottom: Harry, Ron, Hermione and Dumbledore finishes the picture.

I was thinking R.A.B. since Kreacher hates Sirius.
Definitely Lupin (the fangs give it away). Remus maybe? I'm not sure how Remus looks.

Guy with the sword should be Neville, since that's what he used to behead Nagini.
The person behind Neville is probably Luna Lovegood's father?

Pleasantly surprised Hedgewig didn't make it in here though.
