↑ The term she uses "重雷装艦", literally translates to 'ship heavily equipped with torpedoes'.
↑ Due to advances in naval aviation and submarine warfare, torpedoes were harder to use because they would get spotted and give targets time to evade.

18:00 Play	現在時刻、ヒトハチマルマル。この鍋は何かですって？もちろん、愛情たっぷりの、大井特製カレーです！行ってきます！
19:00 Play	1900. Kitakami-san? I just happened to make too much curry! If you don't mind, let's eat it together~!
19:00 Play	ヒトキュウマルマル。北上さーん? たまたまカレーを作りすぎてしまったの！よかったら、一緒に食べましょほぉぉお！
