well technically hes not a werewolve, hes a shapeshifter, bcuz he can change into 狼, オオカミ form without the whole full moon thing. but no he cant die または age. lol (lucky)
Yes he can when he stops phasing. Remember he told Bella he will age when he can control his phasing and theres no threat to keep him. Of course when that happens like all humans will grow old and die, just like his grandfather who was a 狼, オオカミ and the others elders who were オオカミ too.
