Even though Jiko expected to see changes in Haruki #1, she was shocked by his wounds and bruises. Perhaps, for Jiko, Haruki #1’s cuts and bruises are a tangible reminder that her son is going to suffer and die in the war. Haruki #1 attempted to explain these away as the typical injuries from military training, which, of course, was not true. This is similar to how Nao tried to explain away her own cuts and bruises to Tomoko.
