Inazuma manifests as a destroyer character inspired by the historical Imperial Japanese Navy vessel of the same name. She serves as part of the Akatsuki-class destroyer group alongside sisters Akatsuki, Hibiki, and Ikazuchi within the Sixth Destroyer Division, which historically operated under the First Torpedo Squadron during wartime periods. Her personality displays a gentle and timid nature alongside a distinct aversion to conflict. She frequently voices a preference for peaceful moments, stating "I really like time of peace like this too, when nothing is happening." Despite this disposition, she demonstrates resolve in combat, declaring "See how Inazuma is when she's serious!" upon joining a fleet. Her speech incorporates the distinctive verbal tic "nanodesu." A significant background element involves her participation in humanitarian actions during the Battle of the Java Sea, rescuing 527 British and American sailors from sunk enemy vessels. This event informs her philosophical conflict about warfare, reflected in MVP dialogue like "I want to win the war, but I also want to save lives... Is that weird?" This duality extends to her reluctance in night battles, where she states, "If possible, I’d like to save those sunken enemy ships as well." Her operational history spans multiple Pacific theaters. Following the Surabaya rescue, she engaged in combat at Kiska, Solomon Islands, New Guinea, and Attu Island, noting "I fought at Kiska, Solomon, New Guinea and Attu Island one after the other... I did my best..." in her library quote. References to collisions with friendly ships like Miyuki and Sendai Maru appear in her major damage docking line: "Beware of ramming." She shares close bonds with her sisters, particularly Ikazuchi. This closeness sometimes leads to confusion, prompting her to question the Admiral in her secretary line: "Commander, um... you aren't mistaking me for someone else are you?" Seasonal dialogues depict participation in communal activities, such as securing flower-viewing spots with Ikazuchi or mediating disputes between Akatsuki and Ikazuchi during sandcastle-building. Her seasonal quotes consistently reflect themes of kindness and support. During Valentine's Day, she offers "Inazuma’s serious chocolate" as a heartfelt gift. White Day interactions show gratitude for reciprocated gifts, while autumn dialogue reveals her crafting teru-teru bouzu dolls to ward off rain. A wedding quote expresses emotional vulnerability: "Commander, you're still here, huh. Eh? You were waiting for me?... Thank you." Mechanically, she wields standard destroyer equipment including 12.7cm Twin Gun Mounts and torpedo launchers. Remodeling at Level 20 (designated Inazuma Kai) significantly improves her combat capabilities, enhancing torpedo and anti-submarine stats while adding an extra equipment slot. Unique bonuses activate when equipped with specific radar-torpedo combinations. Her sinking quote underscores a consistent longing for peace: "I wish I'll be reborn... into a more peaceful world."
