Patriacia O'Brian (abbreviated "Patty") is one of the best friends of Candy from the anime and manga Candy Candy. Although it appears in both the anime and manga, only in the manga you get to see a side basically yandere to Stear. Above all after the death of the same, which he is unable to cope with death, it removes the twinkle in his eyes, and tries suicidarze, but it is prevented by Candy. However in the anime instead we see cries and suffers for the death of Stear but without showing more detail.
