>>2161532>She is already overpowered.She has exactly the "powers" she needs to fulfill her role in the plot. In the original show, that is.
How is some supplementary spinoff manga that's basically released just for fun & fanservice even remotely relevant?
Besides, she was trained for fighting since childhood, and manages to land elegantly after a fall from a cramped airvent, and we know that she does regular exercise (swimming)
Granted, there's also alot of reasons why she should be frailer than a normal person, but do these exist in spinofverse? And... she would probably be the type to force herself to fight as well as the plan requires, even if it would break her body. She "can be replaced", after all...
Really, anyone who calls Rei a "betraying bitch" must be such a jerk, even Rei Q would notice it and eject the plug on them!
