Ep. 12: Kongou attacks the American Fleet while Iona boards a torpedo to reason with her directly.
Kongou destroys ships of the American Fleet of Fog, prompting Iona and other mental models to contact her. Kongou asserts her duty to eliminate anomalies by destroying Iona and all contacting vessels, including herself, before cutting communications. The I-401 evades her enhanced Super Gravity Cannon and conceals itself, recognizing that direct confrontation is futile. Iona decides to reach Kongou personally, with Gunzou’s support, boarding a torpedo to board her deck. Despite Kongou’s relentless attacks, Iona attempts to reason with her. Kongou traps Iona and initiates self-destruction to kill them both, but the I-401’s Super Gravity Cannon disrupts the sequence. Iona successfully dissuades Kongou, preventing mutual destruction. Kongou befriends Iona as her superstructure collapses. Days later, the I-401 crew delivers a vibration warhead to the U.S. Navy, Takao’s body is restored, and the crew returns to the sea, hoping their actions improve the world.
