Description
Souryuu serves as an aircraft carrier for the Sakura Empire. She possesses a tall, slender frame with waist-length dark blue hair, blue eyes, round glasses, and prominent long bunny ears. Her attire typically consists of a dark green onsen-style uniform with a high collar layered over a white buttoned shirt, a black corset, and a pleated skirt. She wears black thigh-high socks adorned with ribbons, silver-and-red slippers, and a single black fingerless glove on her left hand. After retrofit, she is depicted wielding a long thin pipe.

Her personality reflects seriousness, discipline, and a strong sense of responsibility. She frequently acts as an event coordinator or voice of reason, demonstrated by her efforts to restrain impulsive allies like Akagi during the Lunar New Year Celebration. Souryuu maintains a strict demeanor toward the Commander, admonishing distractions during work and demanding efficient task completion. Despite this stern exterior, she shows concern for others, particularly her sister Hiryuu, whose rebellious phase causes her visible worry. She harbors a deep interest in the traditional Japanese card game Hanafuda, which influences her dialogue and combat mechanics. As affinity with the Commander increases, she reveals a more approachable side, sharing personal reflections and engaging in extended Hanafuda sessions.

Historically, she identifies as the Sakura Empire’s first purpose-built fleet aircraft carrier and avoids discussions of the Battle of Midway, where her counterpart was sunk; this reluctance surfaces in her self-introduction. She shares a close operational bond with her sister ship Hiryuu, reflected in the "Second Carrier Division" skill that significantly boosts her aviation capabilities when they sortie together. Her retrofit ability, "Flowers of Fate," incorporates Hanafuda motifs into combat, launching randomized dive bomber strikes named after card combinations like "Five Brights" and "Boar, Deer, Butterfly."

In story appearances, Souryuu participates in multiple conflicts, including battles against Azur Lane forces and interdimensional threats. During the "XP4 Heroes Coalition - Azur Lane" storyline, she engages in naval operations alongside Hiryuu and Kaga, strategizing escapes and observing battles. She later attends cultural activities like tea ceremonies with allies such as Hood and Helena. In "XP4 Heroes Coalition - AKB0048," she confronts DES soldiers and witnesses idol performances, while in "XP4 Heroes Coalition - Neo-City Diaries," she monitors broadcasts about rule changes. In the spin-off *Crosswave*, she supports Akagi and Kaga during the Joint Military Exercise, cutting short a vacation to assist. Her interactions with Yorktown hint at unresolved historical tensions, noted in a sortie line stating, "I can’t stay mad at you," referencing Yorktown’s role in her sinking at Midway.

Her development shows subtle shifts from rigidity to measured flexibility. In pledge and high-affinity dialogues, she acknowledges enjoying extended time with the Commander during Hanafuda games, suspecting initial ulterior motives but ultimately accepting closeness. Seasonal Valentine’s Day lines depict evolving strategies to share gifts privately, from elaborate disguises to secluded hideouts. Post-retrofit, she exhibits greater confidence in the Commander’s judgment and expresses proactive concern for Hiryuu’s emotional state. In skins like "The Crane Amidst the Pines," she adopts softer attire for New Year celebrations, participates in teaching children, and invites the Commander to shrine visits, indicating increased sociability. The "Counselor Girl" skin frames her dynamic with Hiryuu through a school-themed narrative where she serves on the Morals Committee.
