Regent is the first Treasure Demon the player encounters. It is a forced encounter in Madarame's Palace. It will only stay in battle for 2 turns before it runs away, and resists or nulls everything except Psy and Nuke. The first available Personas that can hit its weakness are Kodama, who obtains Psi at level 12, and Makami, who starts with Frei at level 15; if these are not available, the skill Lucky Punch, usable by Obariyon at level 9 and Zorro at level 13, should be used to knock it down and initiate a Hold Up; the Rebellion skill, from Apsaras or Succubus, can also be used to increase the chances of a critical hit. It will join immediately without negotiation. While it cannot be equipped and used like a normal Persona, it will be registered in the Compendium, granting the player easy access to its wide range of multi-target attack skills through Fusions.
Fusing Treasure Demons works similar to Element fusion in the Shin Megami Tensei series, allowing a persona to "rank up" or down within its own Arcana, making it easy for the player to obtain any missing personas in their Compendium.
Fusing Regent has the following effects on the various Arcana:
- Rank +2: Emperor, Hermit
- Rank +1: Magician, Hierophant, Chariot, Justice, Fortune, Hanged Man, Death, Star, Sun
- Rank -1: Fool, Priestess, Empress, Lovers, Strength, Temperance, Tower, Moon, Judgement
- Rank -2: Devil
