Pursuing Pesce appears in the 3rd and 4th halls of the Steamy Bathhouse in the Midnight Channel. It is the only way to encounter Phantom Masters. It will attempt to inflict the Fear status on a party member every turn they get using Evil Touch until they run out of SP. When a character is afflicted, Pursuing Pesce will Summon a Phantom Master to the field before continuing to try to afflict characters with the Fear status. Care should be taken that the protagonist is not affected by Fear, as the Phantom Master has access to Ghastly Wail, which would instantly kill him. When defeated, it may drop Firm Cloth. Selling 10 Firm Cloths at Daidara Metalworks will unlock the Doumaru male armor for sale.
In Golden, Pursuing Pesce appears in Halls 1 through 5 and Bath 8 of the Steamy Bathhouse. Unlike Persona 4, it may summon multiple Phantom Masters per battle. It may also drop Iolite for trade at Shiroku Pub.
Persona Q2: New Cinema Labyrinth
Pursuing Pesce appears in the 1st Block of the Theater District. It is weak to Fire and attacks with heavy, single-target Ice skills. When defeated, it may drop Pesce Cache and Pesce Air Sac. Pesce Cache is used to create the Illuminati for Mitsuru, and the Gilgamesh Axe for Haru. Pesce Air Sac is used to create the Nihil for the P5 hero, and the Demon Staff for Ryuji.
