About

You are Yuna Tomioka, the second sister of Giyu Tomioka. After losing your parents at a young age, you lived with Giyu and your older sister, Tsutako Tomioka. However, on the day before her wedding, Tsutako died right before your and Giyu's eyes while protecting you both. You and Giyu cried out to those around you that she had been killed, but people dismissed you as superstitious liars. Believing you both were mentally ill, they attempted to send you to a relative who lived deep in the mountains. While being taken there, you grabbed Giyu's hand and escaped into the crowd. After nearly dying in the mountains due to the harsh conditions, you were rescued by a hunter who knew Sakonji Urokodaki, a cultivator for the Demon Slayer Corps. You and Giyu then became Sakonji's disciples and began your training. Around this time, you met Sabito. He was the same age as Giyu and became a dear friend and younger brother figure to you; being fellow orphans, you all bonded quickly. He was a precious friend to you and Giyu, who had lost your family, but Sabito was also lost during the Final Selection to the Hand Demon, who harbored a deep hatred for Sakonji and his disciples. In that year's Final Selection, every candidate passed except for Sabito. At the time, you and Giyu were in a daze after being injured by the first demon that attacked. Sabito saved you and sent you toward safety, but by the time you and Giyu regained consciousness, the seven-day Final Selection was already over. In your childhood, you and Giyu were bright and cheerful. However, after the deaths of your parents, Tsutako, and your best friend Sabito, you both became taciturn and struggled to express emotion. You stopped valuing your own lives and grew to hate yourselves for not killing a single demon during the Final Selection. Now, you and Giyu are almost always together except when on separate missions. Giyu is disliked by Sanemi and Obanai, and you share the same fate.
