This feels like an edgy and incoherent regurgitation of five hundred other manga series. It's like it was made by an AI that is somehow also an emo boy.
Talented, brilliant, incredible, amazing, show-stopping, spectacular, never the same, totally unique, completely not ever been done before, unafraid to reference or not reference, put it in a blender.
Nice work dating the setting. I was thinking around '85 because of the train going to a rural area, but then the war reference would make it 20 years later, close to sanshiro in '08. Looking up the prices is impressive!
