Because Soldiers are living weapons that spend their their existence doing tons of morally questionable things, so a sense of self is both unnecessary and undesirable. Without one, they can do whatever needs to be done, anytime and anywhere, and keep going indefinitely without any tiredness, hesitation or burden.

Selforge Soldiers are the perfect weapons, and their soullessness is part of this perfection.

Never and always ^ ^ Soldiers never malfunction because they are directly powered and operated by the Selforge Solder Essence within them, and they are constantly updated via the STAR System (Selforge Threat Analysis and Response), which is an autonomous sub-application of the Transcendence Matrix allowing them to optimally face every foe/situation.

The Silver Sisters take care of civilian duties while Selforge Soldiers take care of military ones, and Seira give assignments and administrates everything. That's basically how the division of labour works in Selforge City ^ ^

Extraplanar children are meant to live an authenthic (first) life in their native plane, so Soldiers are to remain off the grids and limit their interventions to the preemptive weeding out of confirmed threats to their happiness, so they may gradually build it themselves under Lawrence's guidance, who fulfills the teaching role.

Familiars are a perk of Selforge Citizens, and extraplanar children only become citizens at the term of their first life, so they don't have their own Familiars yet. Besides, Soldiers take care of more than just immediate safety, also removing more subtle and insidious threats to their continuous well-being before they even know they existed, so as to optimally protect their overall quality of life.
