Main plot of this story comes from these alien invaders known as "Evolutionary Invasion Objects" whose purpose is to slay humanity.The heroes being branded "E-Gene Holders" manifest the spirits of historical figures into a weaponized form (Similar to Shaman King).
What this anime offers is style & is full of it. Character designs are covered in full body armor each displaying their historic spirit & specific traits which is complimented by the eye catches in each episode. One of the highlights of this series is how it is "influenced" by several animes of the past or at least can be compared to. One example is the color tone changing similar to Jojo's Bizarre Adventure's anime adaptation. Other examples include the invaders being similar to "The Blue" from Blue Gender as they evolve with every encounter.The same can be said to either Shaman King or Fate/Zero due to their usage of historical figures.
Sadly, the cast is kind of bland leading to a couple of "erotic" moments thrown in just for the hell of it. The lead Sio Ogura is okay as a military otaku who is just quirky character with a few cool moments. I was hoping for more interaction between the host & their spirit which doesn't really happen until the last episode.
Being based on a ongoing manga, the anime seems to give an passable conclusion as this series won't seem to do will if it goes beyond its limit. However, the music for the anime is excellent; being filled with rock & electronic music which suits the semi-hot blooded tone of the show. In other words, Nobunagun is not the coolest thing ever but at least it knew what it wanted to do; a slightly dark anime where colorful characters kill aliens via power suits while jamming to an engaging OST.
