The heroes were summoned to save the world from waves of demons that spawn when the dragon hourglass runs out of sand.
Before he knows it, he is summoned to another world along with three other heroes, seemingly from different time periods. Naofumi stumbles upon a book about the four legendary heroes when he realizes the book isn’t finished. How did this isekai fare amongst all others?
After reading the book, I didn’t fully quite understand what was going on and decided to give the parent series a try. However, despite all of this, it wasn’t the synopsis of Tate no Yuusa no Nariagari that captured my attention but a spinoff light novel revolving around Motoyasu, the Spear Hero.
It is a genre that refuses to die and it seems like that ideas for these shows are scraping the bottom of the barrel. Isekai shows are oversaturating the anime market these days.
