Description
Yui Kounagi is a teenage girl with shoulder-length black hair, typically pulled into a ponytail secured by small yellow ribbons. Her hairstyle features straight blunt bangs, framing gray eyes. She wears a distinctive school uniform: a white blouse with blue stripes and a matching blue bow. Outside school, her attire shifts to simple purple shirts and skirts with frills, often paired with a lab coat when assisting her grandfather at the family hospital.
Yui nurtures a strong fascination for collecting unusual objects, initially gathering keychains and cellphone charms before progressing to larger dolls. She habitually anthropomorphizes these items, treating them as sentient companions. Her culinary efforts are notoriously unsuccessful, resulting in inedible "magical chemical concoctions." Her personality blends kindness, innocence, and a readiness to trust others. This trusting nature is evident when she agrees without question to share her body with the dream demon Engi Threepiece. She frequently adopts a sisterly demeanor toward people regardless of their age.
Her story begins during a supermarket encounter with protagonist Yumeji Fujiwara, who retrieves a dropped item for her, accidentally glimpsing her underwear. This sparks a slight romantic interest in Yumeji within her. Later, she crosses paths with Merry Nightmare when Merry bumps into her, causing her to drop a valuable object.
Yui's life shifts dramatically when Engi Threepiece, a dream demon seeking vengeance for her elder sister's death, contacts her through dreams. Yui consents to become Engi's vessel, allowing the dream demon to share her body. This partnership evolves into a deep sisterly bond, with Yui comforting Engi during periods of emotional distress over her loss. Initially lacking combat abilities, Yui gradually gains proficiency in wielding Engi's triple-bladed swords ("Sannasubi") in the real world following the defeat of the antagonist Pharos Hercules, signaling her deepening synchronization with Engi.
Her closest human bond remains her childhood friend, Nao Horie. While her direct involvement lessens after the Hercules arc, she occasionally reappears to support the main characters during conflicts involving dream demons. Her character development centers on her transition from a passive collector to an active participant in supernatural battles, facilitated entirely by her symbiotic relationship with Engi.
