Description
Kongou commands as flagship of the First Oriental Fleet within the Fleet of Fog, a sentient warship collective blockading global sea routes. Her original Kongō-class battleship form features distinctive purplish hull markings. She enforces the Admiralty Code with unwavering strictness. Her humanoid mental model appears as a pale-skinned woman with spiky blonde buns, crimson eyes, and light blue lipstick, often clad in a dark purple ballgown reflecting the historical vessel’s British lineage. Typically apathetic, she displays minimal emotion and dislikes activities like underwater submersion but communicates with nearby seagulls.

She assumed flagship duties after predecessor Hyuuga’s sinking by rogue submarine I-401. Overseeing sister ships Kirishima, Haruna, and Hiei, she loses Kirishima and Haruna to defection in the anime. Her warship displaces 31,780 tons, achieves 80 knots, and fields 30 torpedo tubes, 118 photon cannons, 27 missile launchers, a high-voltage discharger, and a city-to-island-level Super-Graviton Cannon. Her Flagship Equipment teleports subordinate Union Cores and 3D-prints hulls from nanomaterials. The mental model generates energy blades, barriers, corrosive spheres, advanced sensors, nanomaterial regeneration, and physical duplication.

In the *Ars Nova* anime, her rigid code adherence spirals into obsession with destroying I-401 and captain Gunzou Chihaya, whom she blames for corrupting Fog vessels. Stripped of flagship status after Kirishima and Haruna defect, she is confined by submarines I-400 and I-402. Breaking free, she absorbs heavy cruiser Maya and light cruisers, merging nanomaterials into a spherical "Berserk Mode" battleship. This form enhances firepower and durability, letting her obliterate 54 Fog vessels in one Super-Graviton strike. Confronting I-401, Iona’s touch to her core triggers emotional collapse; Kongou admits hatred stems from isolation and buried feelings. Post-reform, she defects from the Fog, keeps Maya’s piano, and aids I-401 against Hiei in *Cadenza*, deflecting cannon fire and engaging in close combat.

Manga Kongou operates as a calculating strategist, deploying her fleet and Flagship Equipment to hunt I-401 systematically. Emotionally detached, she shows subtle care for subordinates, designating Hiei as acting flagship. Near methane hydrate deposits, I-401 cripples her vessel with corrosion torpedoes. Severely damaged, she rams Gunzou’s command ship Matsushima II. Surviving, she later rescues Gunzou, revealing a detected "voice" hinting at his role in a future she wishes to witness—signaling departure from prior dogmatism.

Across media, her Union Core—consciousness within the mental model—remains her critical weakness; its destruction kills her permanently. Post-anime reform, she patrols independently, rejecting both Fog rigidity and human alliances, yet sustains a connection to Iona through a promised tea meeting.
