Tsurara Oikawa, a Yuki Onna, serves as Rikuo Nura's trusted attendant within the Nura Clan, a role held since his childhood where she often endured his pranks. After an incident with the Gagoze Alliance four years before the main events, she enrolled at Ukiyoe Middle School in a human guise as Tsurara Oikawa to protect Rikuo more closely, persisting despite his initial reluctance. Standing 150 cm tall, Tsurara possesses long hair blending black, blue, and white hues, marked by two wavy black horizontal lines on one side. Her eyes shift from golden amber in her yōkai form to dark blue in her human disguise. She consistently wears a long white scarf with zigzag patterns and a snowflake-patterned furisode. Her human guise retains similar hair and incorporates her signature scarf with the school uniform. Her personality blends cheerful dedication with fierce loyalty to Rikuo, stemming from a ritual sakazuki exchange that solidified her eternal vow to protect him. She exhibits strong protectiveness, particularly toward Rikuo's human form, and displays visible jealousy when other women like Kana Ienaga or Kejōrō interact closely with him. Yet, she prioritizes Rikuo's well-being, even protecting Kana to prevent his sadness. This dedication sometimes manifests as acknowledged overprotectiveness, potentially risky in emotional situations. Her Yuki Onna heritage grants combat abilities focused on ice and cold wind manipulation. Key techniques include **Noroi no Fubuki, Yukigeshō** (freezing and shattering opponents), **Noroi no Fubuki, Fūsei Kakurei** (generating immobilizing blizzards), and **Noroi no Fubuki, Yukiyama-goroshi** (inducing drowsiness via cold air). She models ice into weapons like naginatas or functional objects like skateboards. Her strategic ingenuity was demonstrated in the Shikoku Arc when she froze her own left eye preemptively to counter Yosuzume's blinding attack, feigning blindness for tactical advantage. Her character development intensified through major conflicts: * **Gyūki Arc**: She protected Rikuo on Mount Nejireme, though defeated and later rescued by him during a confrontation with Gozumaru. * **Shikoku Arc**: She aided Rikuo against Tamazuki, overcoming Yosuzume's interference through foresight and precision. * **Kyoto Arc**: She fought alongside Rikuo against Tsuchigumo and Kidōmaru, participating in joint techniques like "Matoi" while navigating personal jealousy when Rikuo performed it with others. * **Hyaku Monogatari Clan Arc**: Promoted to lead the Nishikigoi district, she established the Tsurara Clan after creating tsukumogami allies like Onryu from antique pots. She earned the respect of the financially critical Arawashi Clan by defending them and their human clients from hostile tsukumogami, cementing her leadership beyond bodyguard duties. In the futsal-themed special *Gekitou Dai Futsal Taikai! Nuragumi W Cup!!*, Tsurara participated as part of the Nura Clan team. Her narrative consistently emphasizes unwavering loyalty to Rikuo, growth from attendant to clan leader, and balancing personal affection with duty.
