This is for a hypothetical. May or may not release the character affiliated with this power.

***Oh noes!***

You encounter an esper with the powerful ability of mind transplant! Not only they can take over your brain, you’re now forced to be co-dependent on the esper because they're draining your lifespan away by sapping away your cognitive functions!

Since they've trained themselves to remain in control of your body longer than just a month, perhaps settling in your body for a few years until ego death… How would your OC handle it?
