Hunger Arcana

The Lust Arcana is an arcana in Persona 4 Golden. Like the Aeon Arcana, the Lust Arcana is not found in standard tarot decks. The Lust Arcana is the Thoth tarot equivalent of the Strength Arcana, numbered XI.

Persona 4 Golden
The Lust Arcana social link is represented by Tohru Adachi, though it is originally presented as the Pierrot Arcana. If the player ranks the link high enough and identifies Adachi as the killer, he is given the choice to reveal his suspicions or hide them. If he reveals his suspicions and later goes to confront Adachi alone, the Arcana reveals itself as the Lust Arcana, and maxes as Lust during the True Ending. If the player hides his suspicions about Adachi and later assists Adachi in disposing of evidence incriminating him, the Social Link maxes as Pierrot, though the game ends on a new Bad Ending.

The game itself considers the Pierrot and Lust Arcanas to be the same Arcana, so maxing out the Link in either way will allow you to summon Magatsu Izanagi, the Ultimate Persona of the Pierrot/Lust Arcana.
