Movie
Description
I-402 functions as a Sen-toku class submarine in the Fleet of Fog, upgraded with advanced Fog technology. Her hull resembles I-401's design in the manga but adopts a teal coloration in the anime. She displaces 3,540 tons surfaced and 6,570 tons submerged, measuring 122 meters in length with a 12-meter beam and 9.7-meter draft. Her propulsion achieves 80 knots, and Wave-Force Armor shields her from one direct hit by a heavy cruiser's Super-Graviton Cannon. Armament comprises eight torpedo tubes, eleven photon cannons for missile defense, and eighteen missile launchers. Despite moderate combat strength, her unparalleled sensors—matched only by sister ship I-400—detect targets precisely beyond fifty miles.
Her mental model appears as an early-teen girl with green eyes and white hair in the manga (greenish in the anime). She typically wears attire chosen by supreme flagship Yamato but favors purplish-pink shades with blue or yellow accents. Polite and unwaveringly loyal to Yamato, she interposes herself to protect her commander. More talkative and independent than sisters I-400 and I-401, she still aligns all actions with Yamato's interests. She occasionally takes initiative, like assisting Takao and I-401 against U-2501 without orders based on her own assessment, and later rescues Takao's core to prevent I-401 from entering a hazardous spatial anomaly zone.
In the manga, she acts as Yamato's guard and attendant. Early missions pair her with I-400 to confront deserter Takao, whom they release after judging her non-threatening. Later tasks involve tracking the Admiralty Code and intelligence gathering: she supplies surveillance data to I-401 during Takao's fight with U-2501, provides Milchkuh coordinates, and retrieves Takao's core. Yamato assigns her as Takao's "warden," leading them to deliver a message to Zuikaku and infiltrate Yokosuka city. There, I-402 handles housework and haggles with humans adeptly. After learning Japanese authorities suspect her Fog origins, she initiates open contact—tacitly approved by Yamato. Her long-term mission with I-400 collects Admiralty Code intelligence for Yamato.
Anime continuity diverges: I-402 and I-400 gain higher autonomy, replacing Kongou as First Oriental Fleet flagships. They sink I-401 after she breaches the Iwo Jima blockade, then pursue Takao upon discovering her intervention. Defeated by Takao, they sink in the engagement. The *Ars Nova DC* movie retains her established anime role.
Supplementary media expands her profile: *Salty Road* confirms her cooking skills. Additional materials depict her as an otaku enamored with drama CDs, voice acting, and "moe," and she dubs Takao "Tsundere Heavy Cruiser." Her connection to I-400 involves joined cores, theoretically enhancing joint combat efficacy. She maintains professionalism toward rebellious I-401 but assists when it serves Yamato. Her supervision of Takao shifts to cooperation during their Yokosuka mission.
