The Rising of the Shield Hero
Where Devil is a Part-Timer is a reverse Isakai anime, The Rising of the Shield Hero is the embodiment of the genre. The story follows Naofumi Iwatani, an easygoing kid that one day finds himself transported to a parallel world alongside three other young men.
They quickly learned that they were summoned to serve as a part of the Cardinal Heroes, whose main goal is to fight interdimensional monsters called Waves. Iwatani then receives a Legendary Shield to help compliment the other members of the group in a support role.
It isn’t long before our hopeful protagonist receives a roadblock, though, as he’s cast out by the nobility for a crime he didn’t commit. Now, with the help of a lowly slave, Raphtalia, Iwatani must grind small quests and level up to become the greatest hero in the land.
While that may sound like a cliche, The Rising of the Shield Hero story does manage to separate itself from the pack, evoking strong emotions from the betrayal and hardship the main character has to suffer through.
