↑ She's making a pun on how her name sounds like "around, like, almost". She does this all morning.
↑ Vitamin deficiencies (namely beriberi, thiamine deficiency) were a serious problem for the 19th century Japanese navy. Dietary changes such as barley rice resolved this in the Navy by WWII, but the Army was skeptical of the research and suffered beriberi throughout the war. Submariner diets must also account for Vitamin D deficiency.
↑ After getting damaged by depth charges at Okinawa, a dud was found on her conning tower after she surfaced.
