Many anime series fall under the fantasy genre, giving creators free rein regarding character design. They use it to their advantage, making characters as old or young as they please with bold appearances. Some characters like Rukia Kuchiki from Bleach and Zeref Dragneel from Fairy Tail do not look their age despite being positively ancient.

There are all kinds of characters in anime who experience longevity because of their supernatural dispositions or some external substance, like the Devil Fruits in One Piece. Of these diverse heroes, villains, and everything in between, some are more than a hundred years old, thriving in their respective universes.
