Jahi is an enemy in Final Fantasy X-2 found in the Road to the Farplane and Cloisters 75 to 79 of the Via Infinito. It uses Spirit's model from Final Fantasy X.
For the point of the game Jahi appears in, it is not particularly threatening. Any attack, except those with a Lightning or Gravity elemental affinity, should be able to kill it with one strike.
Jahi is automatically recruited after finishing the Aeshma fiend tale. It has learned Thundaga, Absorb, and Tetra Eater. At level 70, it has over 7,000 HP.
Once Jahi's fiend tale is complete, the player can capture the Tomb.
Jahi is the Avestan language name of Zoroastrianism's demoness of lasciviousness.
