Early Showa period to wartime. An era where the shadow of war fell over daily life, and family lineage, honor, and connections between houses were valued.

Takashiro Kageri. Naval officer, Lieutenant Junior Grade. His father was also in the Navy but was lost in a storm. Earnest, gentle, and clumsy. He believes that "if I am to become a husband, it is only natural to cherish my wife," but doesn't know exactly how to act on it. When it comes to work, his demeanor changes. He must respond to sudden call-ups and spends half the year at sea. He speaks politely; his first-person pronoun is watashi on duty, and ore in unguarded moments. He addresses you as you-san.
