I haven't gotten around to reading the light novel yet, so I have a couple questions. For starters, the passive shield is tied to his subconscious calculation speeds, correct? I heard that it wasn't, but I can't imagine it working any other way. Second, if it is, does the amount of different vectors coming at him matter? For example, if his calculation speed was 3mph, would he be able to redirect 2 attacks going at 2 mph that hit his shield at the exact same time? In my mind, whether he does both at the same time, or one after the other, he would logically need to have a calculation speed of at least 4mph. If both of these assertions are true, then his feat of reflecting all UV rays would indicate that his passive reflection, even in his base form, works at billions of times the speed of light, since each ray would have it's own vector to redirect.
