Arpeggio of Blue Steel

The Power to Open a Path

Kongou obliterates the ships of the American Fleet of Fog and Iona, along the other mental models, make contact with Kongou in an attempt to bring her to her senses. However, Kongou claims that it's her duty to prevent further anomalies to the Fog by destroying Iona and all ships who come in contact with her, including herself, before locking down all communications. After barely deflecting an attack of Kongou's enhanced Super Gravity Cannon, the I-401 conceals itself, knowing that confronting her directly is useless, when Iona decides to reach Kongou and confront her face to face. Gunzō agrees with her plan and after evading a massive barrage of attacks, Iona boards a torpedo to reach Kongou's deck. Iona attempts to reason with Kongou who keeps attacking her until she finally traps Iona and prepares to self destruct herself to kill both, when the sequence is disrupted by I-401's Super Gravity Cannon. In the end, Iona suceeds to dissuade Kongou and prevents the destruction of both. The reformed Kongou befriends Iona while the superstructure created by her collapses. Days later, as the I-401's crew delivers the vibration warhead to the U.S. Navy as intended, Takao's body is restored and they return to the sea, hoping that their actions have helped change the world for the better.
