Another of my old characters, although her iterations were somewhat varied through the years~

It's a low-level phantom , reincarnated as a human and had her memories from previous [allegedly] life installed to her. Can get confused over the fact of having memories from two different lives, both anthromorph and human.
As all phantoms - orderly and controlling, yet imbued with guilt and responsibility over what she and her phantomic powers caused to 'her brother's' early years[and the rest of life by extension], thus displays solicitude that sometimes turns overbearing.
Researching consequences of unaccountable use of phantom powers convinced her to seek a way to share responsibility for their use with those they may affect.

After getting past-self memories back and till the Agency disbandment she's worked in one of its labs for research of mechanisms of causality and constructing a machine to study it's principles, processes and effects, finding a way to diminish its detrimental influence on mutations, conducting simple causality experiments in laboratory conditions for studying small entropic processes, forecasting variants of future, as well as applying the research data in other scientific branches. Far from the machines full potential, but all what the low-level phantom in frail human body can be asked to provide by operating it. [By testing and operating the machine Tsuru got mutations corresponding with her phantomic 'appearance']
M-854 unit, named over its designated project, comprised of a team of specialist in a set of different scientific fields, for a brief period of final stages of the machine development was joined by Nethermane himself.
