Poseidoness

Poseidoness is the queen of the northern seas and the guardian of the Silver Orb.

Encyclopedia Entry
''“The Queen over the Northern Sea. Proud of her physical and magical abilities, she is even stronger than the Kraken Queen of the Southern Seas. Though she is strict, she holds no cruelty of malice. Ruling over the northern half of the seas, she metes out suitable punishments to those that disturb the peace.''

''Though she’s able to live on fish and seaweed, she enjoys the taste of human semen. On the occasions when she can enjoy some, she skillfully uses her tentacles to squeeze it out. She does not attack men, however. Her milking is reserved for criminals of the sea, and those who challenge her and lose.”''

Battle Overview
She’s a very powerful enemy that uses both status attacks and binding moves. You have to summon both Sylph and Gnome to reduce damage as Sylph will let you avoid paralysis and Gnome will let you break free of her binds.

If you defeated her, some dialogue happens and she will hand you over the Silver Orb.

If Luka loses, he’ll become her plaything.

Trivia

 * Out of all four of the Guardians of the Directions, Poseidoness is the only one Luka can actually defeat without exterior assistance. Kraken is defeated by Luka’s superpowered angel side when Alice puts Luka to sleep, Sphinx is an unwinnable fight, and Yamata no Orochi is sealed by Tamamo.
