The sadest moment is the series
What do you think is the sadest moment in ths series?
For me was betwen episode 9 when Akemi was telling Shuji that she loved him and then switch to a scene where Astushi was saying that he didn't wanted to die and wanted to go with Akemi. Also when i realized the irony that Astushi joined the army to protect Akemi but she ends up dying.
