How very odd, [says Akechi as if he doesn't have personal experience with his powers being locked away, because he is just a normal boy and there's nothing to worry about here.]

It's possible, however. Some people have proposed already that this world is, shall we say, "loading?" It may be that it hasn't reached the resource for "powers" yet, in the same way it hasn't yet reached a need for hunger, thirst, or sleep.
