PetalburgShipping (Japanese: ハルマサ HaruMasa. Please note the reverse female/male name order used to denote the dominant partner in the ship) is the name for the ship between main-character siblings May and Max. Despite the incestuous nature of this ship, the couple does have a small band of fans.
Very few hints exist for PetalburgShipping, mostly Max hugging or running over to May at the first sign of danger and May worrying about him, and virtually all of them can be dismissed as the affection that most siblings have for each other.
