Deep Sea Dolphin (海王ディープシー ダルフィン, dīpu shī darufin^?, Runic: ᛞᛅᛚᛈᚼᛁᚾ Dolphin) is one of the five subordinate mazoku under service of Ruby Eye Shabranigdu, the ultimate king of darkness on the Slayers plane (above Shabranigdu lies the Lord of Nightmares). Out of all of the Demon King's subordinates, she is the one that we know least about.

Character Overview

Residing in the Demon Sea, Deep Sea holds up the south-east corner of the mazoku barrier in place before the destruction of Hellmaster Fibrizo. Little to nothing is known about her. She favours the aspect of a beautiful, aristocratic and delicate young woman with long dark hair and a lavish jewel-incrusted blue robe. Her true astral form was never shown, not even in illustrations.

Considering her name, her domain, and the water-themed spell drawing from her power, Dolphin is strongly implied to have some measure of control over Water. Moreover, like many high-ranking mazoku, Dolphin is capable of intricately manipulating space, being able to displace Milgazia and Memphis miles away without them moving. And in the manga, she can enter people's mental landscapes.

Personality wise, in the novel she appears coldly collected and duty-bound. In the manga, she curses Lina Inverse for foiling her plans, but is more amused than angry by the turn of events. (Though perhaps because her overall plan is still ongoing.) Considering how she has a hand in her Priestess's intricate schemes, and how she uses Lyos's doubts and despair to lure him with kind words and a mask of benevolence, she also seems pretty intelligent, conniving and manipulative.

There were rumors that she and Greater Beast Zelas Metallium were hostile towards one another; not only is this unfounded, but there is good evidence against it- the only known picture of Dolphin features her alongside Zelas Metallium. Slayers fanon also concocted similarly baseless assertions that Deep Sea Dolphin went insane following the aftermath of the Kōma War; this is also false.

Dophin has one general and one priest, named Riksfalto and Huraker. The spells calling upon her power are the Dolph Strash and the Dolph Zoke. Finally, her name is among those listed on the Plane chart and based on Vepar in the Ars Goetia.

Role in the novels

Dolphin and Zelas only make a short cameo in the novel, guiding Lina and Gourry Gabriev to the pocket dimension where the third fragment of their master awaits them, as per his orders.

Role in the manga

Deep Sea Dolphin's appearance in the manga.

In Slayers: Knight of Aqua Lord, Dolphin is stated to have sent Riksfalto, with Riksfalto and Huraker discussing her instructions, and her plan to steal the power of the titular Knight of Aqualord and use it to destroy the world.

She makes another short cameo before the final battle. While she is never named, the way she speaks of controlling the Knight and her plans all but states outright her identity. She uses the aspect of a gorgeous, etheral woman to lure Lyos into her grasp. As Lina snaps Lyos back to his senses, Dolphin is irked, but amused at the prospect of the upcoming battle opposing Huraker to Lina and Lyos.
