Demon Slayer's Entertainment District Arc bore some of the most intense battles against Upper Rank demons, but underneath the splashy combat sequences lay deeper character developments. The arc disclosed the complex dynamics of shinobi practices through Tengen Uzui's odd family structure.
Hinatsuru is a 21-year-old kunoichi who serves as one of Tengen Uzui's three wives in Demon Slayer. Born into a shinobi family that ranked second only to the Uzui clan, she received extensive training in ninja techniques from an early age. Following shinobi tradition, her marriage to Tengen was arranged, and she chose to fight beside him in the Demon Slayer Corps.
Hinatsuru denotes everything necessary about supporting characters in Demon Slayer - strategic brilliance, unwavering loyalty, and tactical expertise that demonstrates assertiveness in life-or-death situations. As Tengen's most adult wife, she fuses kunoichi training with emotional cleverness, acting as both battlefield asset and personal anchor. Her poisoned kunai attacks, infiltration skills, and ability to maintain composure under extreme pressure define her.

Hinatsuru has a distinguishing appearance in Demon Slayer that reminisces about her kunoichi background. She has long black hair commonly styled in a ponytail and striking violet eyes bounded by thin eyebrows. She often behaves as the mediator between the other two wives when quarrels arise.
Her usual outfit consists of a short lavender dress with varying square patterns. The sleeveless design features a plunging neckline tied with a red-violet obi where she stores her weapons. She’s dressed in thigh-high brown fishnet stockings and light-colored sandals secured with purple ribbons.
Hinatsuru's nature closely resembles that of the protagonist Tanjiro Kamado. She flaunts kindness, calmness, and fostering qualities even when dealing with chaotic circumstances. Her understanding personality makes her Tengen's primary source of emotional backing among his three wives.
Role of Hinatsuru in Demon Slayer

Hinatsuru plays a key role in the Entertainment District Arc, going undercover at the Kyogoku House with Tengen’s other wives to uncover signs of demon presence. During this mission, she quickly identified Warabihime as a demon but couldn't act immediately due to surveillance.
To escape the dangerous situation, Hinatsuru made the strategic decision to poison herself, allowing her to be removed from the brothel. This sacrifice provided crucial intelligence to Tengen in Demon Slayer.
Her most significant weapon is the wisteria-laced kunai collection. These specially designed weapons hold poison strong enough to paralyze common demons for half a day. And her direct fighting style pivots around ninjutsu techniques and weapon mastery. She shows exceptional skill with kunai and outstanding acrobatic abilities during battles.

During the climactic battle against Gyutaro, Hinatsuru established her worth as a combatant in the series. Despite healing from self-inflicted poisoning, she came onto the battlefield at a critical moment. Her storm of kunai attacks made the opening Tengen and Tanjiro needed to press their attack.
Final Thought
Hinatsuru showcases the strength found in supporting characters throughout Demon Slayer. Her hybrid of tactical intelligence, combat skills, and unrestrained maturity makes her a priceless support. Via her actions during the Entertainment District Arc, she portrays her heroism in many forms. Her readiness to endure personal harm for the greater good presents the dedication required to fight against demon threats.
