Yuuto Suou is a boy from our everyday reality who has wandered into another world at the dawn of war called Yggdrasil. Here in this world, countless nobles are fighting for dominance and it's survival of the fittest. For sixteen-year-old Hayato though, all he had to do was call on his knowledge from our world as his weapon. This leads to him rising to command a few thousand troops as their suzerain (patriarch). The story now follows this boy who became King in another world and is surrounded by beautiful Einherjar who swear their allegiance to him.

If you ever want to feel really good about yourself, remember that you are not the author of this series. Oh my god, this anime is bad. So it’s about some dude who we guess was sent to another world and he’s super OP becoming the patriarch of different clans to protect them from being decimated or abused. He wants to go home it seems like and has a magical smartphone which allows him to call some girl in reality who is clearly wanting him. It was just kinda dropped on the viewer with zero explanation. So anyway, members of each clan want to marry him which is fine for a harem, but EVERYONE either calls him onii-sama or father which is just beyond revolting for this generic character. Not to mention too, no character is really stand out thus far.There are also lesbian lolis, or at least they are fanservicey, which is awkward since they are sisters. Then on top of this train wreck of a sundae probably made with dirty toilet water, the art is atrocious. It doesn’t even seem to be layered properly and it looks oddly dull even for brighter colors. Thank God, Isekai Mou sexy slave anime is so much more better than this. Do yourself a favor and avoid this like the plague unless you like max cringe isekai anime that doesn’t really have anything going for it.
