Hitachi Chigusa is a 16-year-old human adventurer hailing from the Far East. Her black, medium-length hair often obscures her face, revealing dark green eyes when parted. Bandages wrap her neck and left upper leg. She wears a lavender kimono with a red sash at the waist and a single piece of red thigh armor on her left leg, self-conscious of her modest figure. Pronounced timidity and shyness define her personality, especially around strangers; she prefers solitude but finds openness and comfort with childhood friends. Despite her reserved nature, fierce loyalty to her Familia and profound courage emerge when protecting allies, particularly in life-threatening situations. Her emotional resilience surfaces during crises, refusing to abandon wounded comrades or confronting overwhelming foes. Orphaned young, she was adopted and raised by the deity Takemikazuchi, becoming a core member of his Familia. Her childhood bonds include Kashima Ouka, Mikoto Yamato, and Haruhime Sanjouno, who later joined the Hestia Familia. Her alias, "Twin Wings Girl," symbolizes unwavering devotion and partnership. Extensively trained by Takemikazuchi, she mastered multiple martial arts and weapons, excelling in archery—surpassing Mikoto's skill. After leveling up to Level 2 following the Ishtar Familia conflict, her recorded stats were Strength (I23), Endurance (I16), Dexterity (I36), Agility (I32), and Magic (I0). Her Development Ability, Abnormal Resistance, grants immunity to poison and status ailments, vital for dungeon survival. She later wielded the "Black Rabbit Horse," a specialized bow crafted by Welf Crozzo to enhance her archery. Chigusa shares her closest rapport with Mikoto, confiding openly. She harbors unspoken romantic feelings for her childhood friend Ouka, evident when she intervened to prevent his sacrifice during the Black Goliath battle, nursing his injuries afterward. Her dynamic with Haruhime remains rooted in their shared past. Spin-off media like "Memoria Freese" show her collaborating with Ottar of the Freya Familia, displaying mutual understanding despite minimal dialogue. Her story arcs span multiple conflicts: - During a middle-floor dungeon expedition, severe injuries forced her retreat, inadvertently endangering Bell Cranel's party; she later joined the rescue to apologize. - While in a faction alliance, she was infected by seeds from an enhanced "Moss Huge" variant on the 25th floor; this near-fatal injury resolved when Bell defeated the monster. - Her memories were altered under Freya’s city-wide charm; terrified when Bell confronted her, she regained her true memories after Hestia nullified the enchantment and aided in Bell’s rescue. - She participated in the "Faction War," guarding strategist Liliruca Arde. Though her group fell to the adversary Hegni, her efforts weakened him, facilitating Ryuu Lion’s victory. Her role prominently featured the Moss Huge incident during the Hestia Familia’s expedition, where she was parasitized before Bell’s intervention.
