Incredible work, but it feels like it might be a bit boring in the future.
The story starts out by exploring the horrors of war, and how it affects the mentality of someone who is in particular gentle in spirit.
From there, it kind of changed to: "What'll happen if that gentle spirit is given power?"
And currently, it seems to want to explore: "What'll happen if all the Japanese will meet up?"
The logical conclusion for this manga feels like it should be: "When will the MC defect?"
I hope it won't get dull, trying to prolong the same fights.
