Mokoi are spirits of evil in Australian Murngin folklore that live in the jungle and move at night. They are the reincarnation of the "shadow soul" of humans and kill those who use dark magic. They would also kidnap and eat children at night, sometimes causing war with humans.
Mokoi is summoned by Raidou Kuzunoha XIV when using the physical skill, Mokoi Boomerang when being a party member and fighting him.

A Mokoi can be found in Nihonbashi and initiates the "One Mokoi's Trash...", requesting the protagonist find him various antiquities. After bringing him the items, Mokoi rewards him with Kaiwan's essence.

Trivia[]
Although it is, like any demon, optional to recruit or keep in the actual games, a Mokoi seems to make up a very important part of Raidou Kuzunoha XIV's "canonical" demon team. In every single appearance Raidou has made outside of his own games where he summons demons (that is, Devil Summoner: Soul Hackers, The Lone Marebito and the "Chronicles" edition of Shin Megami Tensei III: Nocturne), the Mokoi has made a major appearance. It is so important in Chronicles, in fact, that it opens the cutscene before the fight between Raidou and the Demi-fiend, in addition to being one of Raidou's major attacks.
This Mokoi is often seen using abilities that are all but impossible for a playable Mokoi to possess, such as a powerful boomerang attack. It also has very high stats when targetable in Soul Hackers.
The only other demon to feature so consistently on Raidou's team is Moh Shuvuu.
