I am still wondering how we have paper ships that never existed such as Izumo and Georgia, but we don't get the actual ships that did exist (Iowa and Yamato).
The more that I think about it, the weirder it seems; do most Sakura girls have 4 ears? If they are animals it would be logical for them to have some animal features such as ears, but do they still have regular human ears even though we never see them because they are always covered by their hair?
