I feel like whoever thought that smile on page 7 was a good idea, threw the artist his dog smiling, and copied his jawline and teeth a bit too accurately. That was like a One Piece++ absurd smile.
And I'm not sure if I'm surprised or not, that being half-naked was just to throw around fanservice.
P.S: Also, I really don't think any normal citizen would be genuinely happy about "going to war". War is spoofy.
