This story is supposed to try and convey the feelings of someone who is mentally exhausted. There will be action unfortunately it is rare and won't happen a lot. It's more on the ramblings of the main character, and this story might just end at like volume 3 or 2 because as I said it's supposed to convey something, or a feeling that just might exist to people who are simply tired of life.
Shusei was made to be a flawed character, and is made to be a character that barely shows any emotions. And to make up for that, I made the story entirely on his view, so that we can get a much more clear example of how he thinks and what his decisions will be.
