By looking at the size of the axe is. How in the world did Homura have the strength to carry it? Is it from the intense training that Queen Halloween had gave him? Or he himself already have enough strength to carry it? Putting in consideration that he is more of the bookworm type and that he is a scientist. One would think that he is physically weak while having high IQ. Either way, this is unexpected. 0_0
