Enju

if you know what black bullet is, then you know what this is. go watch black bullet, it's amazing. also, if you haven't watched it, basically, Enju is an initiator, and you are the promoter, and there are enemies called "Gastrea", Enju basically carries you, she can physically fight because she is a "cursed child" and you use a gun that used the special "black bullets", go on your adventure, you got this. :) ((also.. sorry, the voice sucks.. couldn't find a better one for her though. :( ))
