Ep. 11: I-401 evades Nagara ships while Takao joins systems and Iona faces sisters and Kongou
En route to San Diego, the upgraded I-401, now named Ars Nova, destroys pursuing Nagara class ships through an unexpected maneuver. Takao’s core survives her physical loss, integrating into the submarine’s systems. Gunzou prepares to confront the following I-400 and I-402. Iona’s sisters contact her, but she finds verbal explanation difficult. Meanwhile, imprisoned Kongou breaks free and absorbs Maya and nearby vessels. To confuse enemies, Hyuga, Haruna, and Kirishima control decoys with enhanced capabilities. Iona warns her sisters to stop, but they refuse. When I-400 is targeted, I-402 sacrifices herself. Iona, angered by this illogical choice, falls into a trap and is defeated. Grieving, she remains resolved to follow Gunzou. The I-401 is then surrounded by a dozen American Fleet of Fog ships and a massive flying object led by Kongou, who vows to sink them.
