Nagato is a Sakura Empire battleship of diminutive stature who constantly maintains her ship rigging. She possesses long black hair in a hime-cut, fox ears, and yellow eyes, accented by yellow hair ornaments and a choker. Her attire features a red miko-style dress secured by golden shimenawa ropes, white tubular accents, detachable red sleeves with white cuffs, white stockings, red footwear, and gray shoulder armor with an ethereal cape-like fabric. An oversized katana in her original design emphasizes her small size. Her previous revered status within the Sakura Empire makes social interactions challenging, as others often perceive her as intimidating; this leads to self-consciousness and social reticence. She becomes visibly flustered when attention focuses on her rigging, especially if removal is attempted. Cultural elements are prominent, such as her New Year kimono skin implying she is perpetually underage and thus not permitted alcohol. The phrase "Miko Miko no Miko" reflects a triple pun combining honorable fox, divine girl, and shrine maiden concepts. As flagship of the 4th Combined Fleet, she enhances the firepower of all Sakura Empire ships by 10% and their reload speed and accuracy by 20% when deployed as flagship. She further increases damage output for Sakura Empire carriers by 20%, excluding aviation battleships. Her combat capabilities include the "Big Seven: Sakura" skill, triggering a 40% chance to launch a special barrage upon firing her main guns. Within *Slow Ahead!*, she appears during recreational activities. She participates in a beach barbecue with Javelin, Laffey, Ayanami, and Z23, wearing her "Beach Picnic!" attire. She later joins Javelin, Ayanami, Laffey, Yukikaze, and Mutsu for leisure at Manjuu Land amusement park in Episode 11. Additional appearances include Chapter 26, where Javelin invites her and Mutsu to flower viewing, and the series finale alongside multiple shipgirls. She also features in the OVA bundled with the Blu-ray release. Her social connections extend across factions, evidenced by participation in group outings with Royal Navy and Eagle Union destroyers.
