Hapi Nis is a recurring character in the planet Teral storyline.



Unlike most Harpies Hapi is not interested in dominating the planet and often slacks off rather than helping her sisters in their plans. She spends most of her time speaking with her pet Monster Humo.

Hapi has an obsessive personality and devotes herself very seriously to whatever her newest obsession is. This is seen when she first saw Dio and fell in love with him purely based off his looks. After Dio tried to explain to her that he was already interested in someone else and that she should look for a person that she loves based on their character rather than their looks this backfires and Hapi becomes completely obsessed and in love with Dio for his personality and ideals and proceeds to bite him in the neck, rendering him paralyzed. Even after being beaten by Everett and being told by Dio to not follow them, she eventually looks for Dio still obsessed and in love with him hoping that she could seduce him into falling in love with her despite all attempts failing.

Being a Harpy Hapi has all the basic abilities that every Harpy has

  • Flight: Hapi can use her wings to fly into the air,
  • Paralyzing Bite: Hapi bites the neck of a person and causes their entire body to be unable to move except for the head.
  • True Form Transformation: Hapi can transform into her true form which changes the sclera of her eyes to become black and her pupils to turn red.
