OVA
Description
Chigusa Hitachi is a human adventurer of the Takemikazuchi Familia in Orario. Hailing from the Far East, she was orphaned young and later taken in by the god Takemikazuchi, ultimately joining his familia. Her childhood bonds include Ōka Kashima and Mikoto Yamato within the same familia, and Haruhime Sanjouno, who later joins the Hestia Familia.

She possesses medium-length black hair that usually obscures her dark green eyes. Her typical attire includes bandages wrapped around her neck and left upper leg, a lavender kimono, a red cloth tied at her waist, and a primary red thigh piece as armor on her left leg. Chigusa is self-conscious about her physical appearance, specifically her small chest.

Personality-wise, Chigusa is notably timid and shy, especially around strangers, often avoiding social interactions. Despite this, she shows strong loyalty to her familia and courage when protecting allies. She feels most comfortable speaking openly with Mikoto Yamato and harbors unspoken romantic feelings for Ōka Kashima.

As an adventurer, Chigusa started at Level 1 and advanced to Level 2 following a major battle against the Ishtar Familia. Her Level 2 stats are Strength I23, Endurance I16, Dexterity I36, Agility I32, and Magic I0. She possesses the Development Ability "Abnormal Status Resistance," protecting her from monster-induced debilitations in the dungeon. Though an all-rounder combatant, her archery skills are exceptional, surpassing even Mikoto's. After the Xenos arc, she wields the large bow "Black Rabbit Horse," crafted by Welf Crozzo, enhancing her archery.

Key involvements include: During a dungeon expedition to the middle floors in Volume 5, she was gravely wounded, forcing a retreat. Her group encountered Bell Cranel and inadvertently caused a "Pass Parade" incident; she later joined the rescue and apologized to Bell. In Volume 12, during a faction alliance expedition, enhanced "Moss Huge" seeds infected her, nearly proving fatal until Bell Cranel saved her by defeating the monster. She aided in uncovering the truth about the wanted Ryū Lion in Volume 13 and supported Bell Cranel's search. When Freya enchanted Orario in Volume 17, altering memories, Chigusa was initially affected and reacted fearfully to Bell's confusion. After Hestia dispelled the charm, she regrouped with Takemikazuchi and allies to rescue Bell. During the Great Faction War (Volume 18), she guarded the alliance commander, Liliruca Arde, and contributed to weakening the formidable adversary Hegni, enabling Ryū Lion's victory.

Chigusa is nicknamed the "Twin Wings Girl." In the mobile game "Memoria Freese," she shares notable interactions with Ottar, leader of the Freya Familia, including scenarios where they collaborate effectively despite minimal dialogue.
