In other words....like this.

Would. You. Shut. UP!?

During the WW2, many journalist and authors served under the Army and Navy. They are stationed in various ships such as carriers, cruisers, submarines, etc.

For example, Niwa Fumio who is stationed on Choukai had his right arm injured during the Battle of Savo Island. He wrote the condition on board in his book "Kaisen" (en: Naval Engagement). The book can be easily found in old book store and is a recommended reading to know about the situation on board during that era from the eyes of an outsider. Kiyomizu Susumu who is stationed on board Tenryuu during the same battle wrote it in an article titled "Solomon Kaisen Jugun", but he ended his life with the ship on Bismarck Sea on Showa 18.

By the way, when Umino Juuzou is stationed on Aoba, there's also three other media staffs present. Each one of them are placed on each ships of the 6th Cruiser Division.

Please give a word on how you feel to be the only Oni left without promotion to Hime and having a gloomy life when you're already living in the dark of the abyss

There's talk about how Aoba's personality might be based of Umino Juuzou, the author working under Navy who served on board for four months.
