Plot.
Naofumi Iwatani, an easygoing Japanese youth, was summoned into a parallel world along with three other young men from parallel universes to become the world's Cardinal Heroes and fight inter-dimensional hordes of monsters called Waves. Each of the heroes were respectively equipped with their own legendary equipment when summoned. Naofumi happened to receive the Legendary Shield, the sole defensive equipment, while the other heroes received a sword, a spear, and a bow, weapons meant for attack. Unlike the other heroes who are fully supported by the kingdom and gain several strong allies each, Naofumi's luck turns to the worse after his single companion, revealed to be the kingdom's Princess, betrays him, steals all his belongings, and leaves him devoid of all assistance and supplies after she falsely accuses him of sexually assaulting her.
Mocked by the nobility and shunned by everyone from his fellow Heroes to peasants, a now cynical Naofumi is forced to train as a hero alone while working to make ends meet, until he buys from a slave trader a young tanuki demi-human girl named Raphtalia and an egg that hatches into a bird-like monster whom he names "Filo", both quickly growing into adulthood and becoming powerful warriors under his care. As they little by little gain the trust and gratitude of the people with their heroic actions, Naofumi and his companions work together to carry out their mission as saviors as they unravel the mystery of the Waves and the reason why they are a threat not only to their world, but to other worlds as well.

As of April 2019, the light novels and manga have sold a combined 6.2 million copies in Japan, after their sales increased by 1.2 million copies in two months, mainly due to the success of the anime series.
The character Raphtalia was selected as Best Girl for the Crunchyroll Anime Awards in 2020.
Reception and controversy in North America.
When the anime series began airing in North America, the first episode came under controversy. Several "Anime News Network" reviewers criticised the show for its depiction of slavery, raising the question of slavery apologism, and the framing of a false rape accusation. When the show's producer Junichiro Tamura was asked about the controversy, he responded that there "have not been any controversies regarding the series in Japan, so it is difficult to say. In the case there were any controversy domestically, we will try to address all issues with the staff and people involved to bring our customers a better product the next time."
Reviews of subsequent episodes have been generally positive. Theron Martin of "Anime News Network" gave a rating of B− for the first two episodes, stating "the series looks like it's gotten over its initial problematic hump and should hopefully slide into a more agreeable story flow." He gave a B+ rating for the third episode, stating that "the series seems like it's angling to build Naofumi up more as a folk hero than the famously brazen heroes we're used to seeing in fantasy stories" and that "episode 3 gives the best argument to date for the series' possible potential."
However, Timothy Donohoo of "Comic Book Resources" heavily criticized the anime for having an "overpowered protagonist who's seemingly never wrong" and for the "socially contentious undertones", noting that "the series has gotten its fair share of well deserved flak". He further described the show "as just another generic isekai show, and a poorly done one at that", even without what he describes as "unsavory elements". He speculates that some viewers may sympathize with the protagonist, noting that this would "justify the show's label as an 'incel fantasy'".
