Gotta be L for me from Death Note.
Eren from Attack On Titan. I just love his determination to get things done whenever he puts his mind into it. Also, his relationship with Mikasa is adorable.
Professor Remus Lupin from the Harry Potter series.
He had to be the best teacher to have. Ever. Yet, there is some sadness surrounding his character.
My favorite anime character would definitely be Minato Namikaze
