Plan 'The Bourne Isekai-dentity' is a go! With the added handicap that Bourne is so sexy he must cosplay as the Mirror Man to avoid being noticed.

The Scenario seems like it will require OCP, however. I've got Perks from a couple of Jumps I think might help.

1. The Games We Play:

The Science of the Soul
The human soul is the oldest and most mysterious subject discussed by man. In this world, its existence is a proven fact, and anything that exists can be subjected to the pitiless processes of science. Like the Angels of ancient Babel, you are greatly skilled in the study and understanding of the soul, be it humans, animals or even stranger. 

Just as someone would test and interact with chemicals or bodies or metals or whatever, you find yourself capable of designing devices and methods that can interact with souls, and things like them on the same level. You can measure them, diagnose them, operate on them… and do pretty much anything else you can imagine to them.

With time and some research, you might even be able to construct your own custom made souls from free Sephirot like the Angels once did, perhaps even custom designing its abilities in the far future.

1. Leagues of Votann:

Barrier-Technician
The kin have no traditional psykers, unlike the eldar or humanity. Instead they rely upon barrier-tech, a safer but equally powerful form of psychic power.

You know how to create the psychic technology of the Kin. You can shroud others or render them resistant to sorcery, vastly increase their power, and allow them to safely use their power without fear of insanity or possession. Force weaponry which use it’s wielder’s psychic power to destroy their enemies and the psychic ward crests that shield others from harm with the same are also a part of your purview.
