All this was great but it the truth only happens with the conclusion of the story. Whether everything lands, including himself, depends how he interprets the ending of this story. I am holding back my critique, because Kaisei seems so far removed from what I think a person should be... he just feels like he doesn't exist and all he's doing is express his grief at that fact, that he chose to be transparent. So, what now? What are you telling me?
I'm going to have to wait for this answer.
