Rising of the Shield Hero is a recent entry in the anime isekai (person pulled into another world) genre, although the light novel was originally released in 2013 in Japan and 2015 here in the States. The plot of the story is that 4 heroes were summoned to a world of sword and sorcery to combat waves of enemies and save the world (dun dun duuuunnnnn). Each of these heroes are granted a legendary weapon that they need to level; The Sword, The Bow, The Spear, and the Shield. By being bestowed one of these items you are forbidden from using anything other then it for combat. And the stage is now set for the adventure to begin.
