The Midgard Library is a special library association that collects information and history from around the world. The Library is speculated to be located somewhere within Japan since Flavio once stated that many Sakura trees grow near Midgard. Several members from the Midgard Library are sent all over the world in order to solve mysteries, collect lost books and artifacts, collect information, and assist with several cities in their problems. Not only do they archive information, but the Library also heavily invests in housing orphans and children, educating them in the arts, archives, combat, and many other things.
