In the Shin Megami Tensei series, human enemies belonging to the Messian and GaeanRaces can be negotiated with as if they were demons.
Recruitable humans are distinct from standard demons in two ways. The first is that these humans do not incur Magnetite costs when actively summoned within dungeons. The second is that they do not follow the standard Fusion chart and there is no predetermined result when they are used as a fusion material.
The mechanical decision to have recruitable humans not incur Magnetite costs was likely inspired by the in-universe lore. Unlike humans, demons require Magnetite as a source of energy to materialize and maintain physical bodies in the material world.[1]
