Takao blocks the I-401's path to Yokosuka by positioning itself inside the eye of a typhoon and after asserting that any attempts to avoid confront are too risky, Gunzō decides to take Takao head on. After Iona barely evades an attack from Takao's Super Gravity Cannon, Gunzō analyzes the combat data so far and points out that Takao's attacks have had pinpoint accuracy from a distance much greater than its usual sensor capabilities and concludes that it is only possible by having a submarine concealed directly under its hull. Gunzō then orders the crew to ready their own Super Gravity Cannon which they salvaged from their previous battle with the Fog ship Hyūga and uses it to destroy the submarine and force Takao to surrender. Having her systems locked down for 24 hours by Iona to prevent her from give chase to the I-401, Takao wonders about the reasons why Gunzō spared her and takes an interest on him.
