Description
Yui Kōnagi is a young girl first encountered in a supermarket. Her long black hair is typically held in a ponytail, featuring two smaller side strands secured by small yellow ribbons, accompanied by shorter bangs and pale slate blue or grayish-black eyes. White triangles manifest within her eyes when controlled by Engi Threepiece. She usually wears a predominantly white school uniform with blue stripes and a blue bow, but is also seen in casual purple shirts and frilled skirts, or a lab coat while assisting her grandfather.
Her personality centers on kindness and a strong drive to help others, evident when she agrees to become Engi Threepiece's vessel to avenge Engi's elder sister. She exhibits childlike innocence, collecting dolls, keychains, and unusual objects while talking to them as if alive. Yui rarely questions others' motives, such as Engi's request to share her body. She displays a universal sisterly demeanor and initially shows a slight romantic interest in Yumeji Fujiwara upon meeting him. Her relationship with Engi evolves into a supportive, sister-like bond where she comforts Engi during grief.
Yui's history involves meeting Engi in a dream where Engi sought permission to share her body for vengeance. Though initially lacking abilities, Yui eventually accesses Engi's sword skills in the real world, likely due to their strengthened bond following Pharos Hercules's defeat, enabling her direct contribution in confrontations.
Key relationships include Nao Horie, her best friend since elementary school; Engi Threepiece, the dream demon she hosts; Yumeji Fujiwara, whom she befriends after he retrieves an item she dropped; and Merry Nightmare, whom she meets after Merry accidentally bumps into her.
Notable trivia includes her habit of acting as a "big sister" to everyone and her complete inability to cook, producing "magical chemical cooking" deemed inedible even by animals. Her character development remains tied to her supportive role, with no significant arcs beyond the Hercules conflict and deepening camaraderie with Engi.
