This manga is literally on crack. It has a lot of fighting between romans, mongols and gladiators etc. It perfectly shows us the vibes we except from valhalla. The art is good but it is confusing sometimes during fight scenes. The main character has a little bit of confused personality but that is ok for this kind of manga. The overall story is also marvelous. I am really happy to see authors thinking out of the box. Because these days isekai mangas are becoming more and more generic and bad. I highly recommend giving this a try if you want some raw fighting and a unique story.
