Description
I-402 operates as a submarine in the Fleet of Fog, acting as personal guard and attendant to the supreme flagship Yamato. Her vessel is a Fog-enhanced Sen-toku class submarine equipped with advanced sensors exceeding most others, matched only by her sister ship I-400. Armament consists of eight frontal torpedo tubes, photon cannons for anti-missile defense, and missile launchers, shielded by moderately powerful Wave-Force armor resilient against a single hit from a heavy cruiser's Super-Graviton Cannon. The hull design resembles I-401 in the manga but features a teal color scheme in the anime.
Her mental model manifests as an early-teen girl with green eyes and white hair in the manga, shifting to a greenish hue in the anime. Physically, she closely resembles sisters I-400 and I-401, contrasting with other Fog vessel siblings. Clothing changes frequently due to Yamato's fashion interest, though she favors purplish and pinkish colors with blue or yellow accents. Personality-wise, she maintains formal courtesy and unwavering loyalty to Yamato, readily interposing herself against threats. Compared to her sisters, she demonstrates greater independence and talkativeness, often serving as primary communicator when paired with I-400. Despite her loyalty, she occasionally takes autonomous actions aligned with Yamato's broader objectives, such as assisting Takao and I-401 against U-2501.
Within manga continuity, I-402 and I-400 initially confront the defected Takao but judge her non-threatening, permitting her freedom. Later reassigned to locate the Admiralty Code, that mission is aborted. I-402 stays with Yamato while I-400 trails other vessels. When Takao battles U-2501, I-402 voluntarily guides I-401's decoys, supplies surveillance data to Takao, and provides coordinates for the Milchkuh. After Takao's sinking, she retrieves Takao's core and notifies I-401 via quantum communication, citing regional instability. Yamato then tasks I-402 with overseeing Takao as her warden. During this period, I-402 demonstrates proficiency in domestic chores like cooking and housework while managing human interactions in Yokosuka. She eventually initiates open contact with humans upon realizing her identity is suspected, an action tacitly approved by Yamato. Her long-term mission with I-400 involves gathering intelligence on the Admiralty Code.
The anime adaptation diverges: I-402 and I-400 operate as an autonomous unit with sufficient Fleet of Fog authority to supplant Kongou as flagships of the First Oriental Fleet. After I-401 breaches Kongou's Iwo Jima blockade, I-402 and I-400 sink her. Learning Takao rescued I-401, they pursue but are subsequently defeated and sunk.
Relationships define key aspects. She holds absolute devotion to Yamato as commander. With sister ship I-400, she shares joined cores, enhancing their combined threat potential. Despite I-401's rebellion, I-402 offers assistance when it aligns with Yamato's interests. As Takao's warden, she adopts a supervisory role, later depicted in spin-offs like "Salty Road" highlighting her domestic skills. She also accompanies Zuikaku on missions to conceal information about Facility #4.
Additional elements include coining the "Tsundere Heavy Cruiser" label for Takao and expressing a desire for a proper mental model name. She displays otaku tendencies, showing enthusiasm for drama CDs and voice acting concepts like "moe".
