Nephthys

Nephthys (ネフティス) is a "bizarre magician", a magic god, who dwells in a territory beyond a certain layer of the world.

Etymology
is a goddess in Egyptian mythology, part of the Heliopolitan Ennead, associated with death and together with, a protector of mummies.

Personality
Not much is known about Nephthys but he or she is apparently the quick to judge, willing to interfere with the normal world and look down upon Othinus despite her being a magic god herself.

Magic God Othinus Arc
In that world where distance and time doesn't matter, Nephthys first appears after the events of the arc has occurred, with Kamijou Touma saving Othinus and her turning to a depowered 15 centimeter Magic God. The being asks another being that is referred to as an Old Man, if they should interfere now. The Old Man explains that the events that have transpired might hinder Touma's development, though says that he doubts that anyone but them can resolve it now that a magic god is in involved. Nephthys asks for confirmation if they are influencing events by interfering with the existing world, to which the High Priest says that the Old Man isn’t so foolish that he wouldn’t calculate all it out. He then says that it just goes to show to them how different an existence Othinus was, though he doubts that she realizes the truth behind GREMLIN.

Nephthys says that Othinus was a failure, to which the High Priest replies that she reached the level of a magic god and as such Nephthys need not be so cruel when referring to Othinus. Nephthys says that the High Priest is as kind as ever when it comes to judging other, and says that if it didn't come from looking down everyone he might've achieved enlightenment. High Priest then says to Nephthys that they are all lacking in some way, and says Othinus was the same though she went a bit too far, though says that is just the kind of person GREMLIN gathers.

Niang-Niang then appears saying that GREMLIN isn't a fusion of magic and science but an organization that every magic god of every religion can take part in equally. She is questioned to where she has been, to which she says that the concepts of distance and time doesn't matter in this place, as they already know. She says that she can't leave regardless, and even if she did, she'll just garner unwanted attention on a global scale like Othinus. The Old Man magic god asks if it is the same for the others, to which Niang-Niang asks if he has started forgetting things once he had become a mummy. She says that the others, the zombie girl, the chimera, and everyone are here in this layer of the world. Niang-Niang says that it is destiny’s hand that allows them run across each other in the first place in this layer of timelessness and infinite distance. One of them says that being stuck in there is one way of being ecological. They are there because the world is too small for them to live in, though laments that it isn’t being there. Niang-Niang then says that is just the exact reason why she is mad at Othinus, because was so selfish. One of them then says that the strength of the world was enough to withstand everything she did, and says what Othinus has done will not have any real effect on the situation.

Nephthys then asks if the can continue as planned. The Old Man replies that they can as the High Priest had just corrected the disorder caused by Othinus, and says that now, GREMLIN will show its true value.

Suddenly, Aleister Crowley himself appears before them. Here, he comes upon "bizarre magicians" talking about what had transpired, to which he refers to as "GREMLIN". One of these magicians references his absence as of late, though states that Alesiter may have been busy with a side job. Aleister says that he had to let the strength of the world handle Othinus running around free as he had something to prioritize in entering their "divine territory" as it wasn't easy. One of the magicians, referred to as "someone" with a hoarse voice, comments on how if Aleister turned his obsession in destroying magic in the right direction then he too would be part of GREMLIN. Aleister says that he made adjustments to himself that it would not happen, as such he can control something different than them who can only live in a distorted phase. The magician with the hoarse voice asks if science is really wonderful enough for Aleister to indulge himself to that extent. Aleister then comments on how even if took them an eternity, none of them would understand. The magician with the hoarse voice then asks if it has nothing to do with "the single remaining tear stain in his journal".

Aleister is silenced by this, and all remaining expression on his faced vanished as he calls upon his magic name Beast666 and draws out his magic staff. The magician are unperturbed, one of them comments on how is envious of his emotion, though says he should stick around as he says he is about to tie it all together. He tells him that Aiwass, the cornerstone of his plan that he tried so hard to raise is a complete failure and that Aleister will be at his wit's end before long. A moment later, Aleister attacks them.

Character Art Design
Haimura designed Nephthys as he was told. He later made her outfit less revealing and added green markings below her eyes in his final design for her.
