The fight to survive and make it back home or find an elixir that is said to grant immortality?

The manga starts off at first like every other manga that takes place during its time period with the added in ninjas for a sprinkle of flavor. The main character starts off seeming like every other, overpowered or just has some kind of tragic backstory that makes them the way they are, Edgey. Now, as I continued to read this manga, it surprised me with how different it actually was. Sure, the main character has a tragic backstory as mentioned (no surprised there) but the way the character is written is unlike many others. After a certain chapter, I couldn't get enough. Each important character is given a spotlight that is well deserved. You are given insight into why that character is the way they are at the right given time. It gives the reader a nice break from reading all the battle scenes to take a small dive into who that character really is aside from what other characters have said, and what possible events either changed them for the better or the worse.

All in all, I really enjoy this manga and can't wait to continue reading it some more.
