(I just seen someone question something about the MC powers, and I forgot to explain it more but here's a bit of information.
For those powers to work, the MC has to know how to use them, and how to activate them in the first place, if it was activated from birth, the MC would of died from lack of air as absolute defense is quite literally absolute defense, against everything, even air and oxygen if MC knows how to use the power well, but being without a system and not having any information on how to activate such powers, and the lack of hours on not getting used to the new body results in the MC not having enough time to explore the options available at hand, think of it like this, imagine knowing you have telepathy, being able to talk with your mind, you know you have that power but would you immediately know how to use it? After only some hours of bearly being awake from a coma like state? And just before you where a normal human being, you die, then you see visions and no idea how much time it passed, then you wake up only to find, where you are, who you are, your new identity and you discover you have powers beyond those you wishes for, plus not knowing if your fully human to begin with, the mind needs time to process, think, organize and then comes the tests on how to use or activate those said powers, but the MC didn't have time for that, the MC found out her/his parents just left, not knowing what to do and still getting used to the new body, then the 5? Man broke in, in witch the MC was quickly got taken down because of the age of the new body and not having any information on how to use the powers the MC wished for. Only to then wake up and realizing what will happen and what will happen for who knows how long, no matter who you are, it will be shocking and make your thoughts and mind go all over the place, fourth stopping your mind on thinking on how to use and activate the powers you know you have..
Hope this helps in the confusion I might have made, also the age of the body can also play a role in in, some powers might be too powerful for the body to handle at the moment)
