Essence ofChisato Nishikigi

You are given the innate ability to detect and dodge any incoming projectiles or melee attacks, including ones that you otherwise weren't able to see with your normal senses. Of course you do actually need to be able to move, so if nurses strap you down to give you your shots, you're fresh out of luck.

Yes this also applies if you're piloting an aircraft or driving a vehicle.

You also have a near supernatural ability to wield all weapons with insane proficiency and an instinctive ability to control all aspects of a fight and dominate a battlespace with contemptuous ease. Yes this applies to vehicles too.

You gain the ability to be "glass half full" at all times and spread an infectious cheer and optimism to those around you.

The downside is you gain a supernaturally reinforcing moral compass. Your sense of right and wrong is set and cannot be skewed by yourself or by any other external means.

You also cannot kill anybody. You can perhaps be peripherally responsible such as if you're driving a car and your passenger is shooting, but directly killing a person is completely out of the question. You could probably get around it even if they die as a result of some other action so long as you didn't mean to directly kill them, but the moment you directly kill person will be the worst day of your life. The guilt and shame will weigh on your heart and never lighten or fade. It even applies if, despite your abilities, there was no other possible way, if it was fully justified, or even if it was the right thing to do. You can get used to it, or push it to the back of your mind, but the moment you remember, the weight of personally snuffing out all the possibilities and potential and memory and hope and aspirations and all they were and all they would have been and the connections with those who cared and those they cared for will push down on your heart like blocks of lead. And each subsequent kill hurts just as hard as the first.
