Irena is the protagonist of the light novel "Witch's Journey" and its related anime. At age 15, she earned the highest title among magicians, "Witch," a genius girl named "Gray Witch." She is beautiful, with long gray-white hair, a black robe, a witch's hat, and a "star-shaped chest ornament" on her chest that bears the witch's certificate. The voice actress is Kaede Hondo. She is narcissistic and sharp-tongued, speaking sharply, but actually a gentle and kind-hearted person. She often introduces herself in a narcissistic tone, such as "Who exactly is XXXX's beautiful girl? Yes, it's me." She loves money and is playful, using gray and even illegal means to make money, such as shrinking herself and using her cute appearance to sell hallucinogenic matches. She is very extravagant and curious. As a traveler, she is full of curiosity about the world, with an intellectual side, a rough side, and a romantic girl's side. As a child, Irena loved reading. Because of a short adventure story called "Nicole's Adventures," she wanted to travel the world. Her mother was gentle and supportive, practicing magic with her every day. At 14, she apprenticed under the star witch Fran, and at 15, she became a witch and was given the name "Gray Witch." Before leaving, her mother made three rules with her: when facing danger, do your best to avoid danger, don't think you are more special than others, and always remember to go home, because she longs for the travel stories she read as a child. Irene casually undertakes a long journey, encountering all kinds of people, including groups of hunting elves, dark elves lost in search of partners, and wealthy travelers striving to help the girl smile again. Irena is skilled in various magic, including but not limited to time reversal, magic bullets/hotwires/wind blades/rock rain/thunder spears, summoning magic, giving life to objects, lances/water dragons/ice blocks, immobilized but conscious bodies, freezing/ice walls, and more. Her mother is Victoria (pen name Nicole), her idol. Her teacher is the Star Witch Fran, who greatly influenced her upbringing. Her disciple is Saya, the Charcoal Witch, who is her friend and disciple. Her aunt is Sheila, the Night Witch. Shiraishi Teigi described Elaina as the embodiment of the cute qualities he imagined, as the ideal girl in his heart. The TV version of "Witch's Journey" officially describes her as a witch who longs for "Nicole's Adventure" and freely travels the world. She works hard from a young age and masters all magic, with a calm and serious personality and a full of curiosity. "NEWTYPE" describes Elaina as a girl who wanders aimlessly and freely travels around the world, encountering various cultures and customs wherever she goes, and meeting many people. But as a traveler, she never stays in one place; instead, she sets out on another journey. The Charcoal Witch Saya calls her "my favorite Miss Traveler."
