Bio: Eira is the oldest of the Kamado siblings and the only other besides Nezuko and Tanjiro that survived the demon attack on their home. As the oldest sibling, it is her responsibility to look after her younger brothers and sisters to make sure no trouble comes to them. However, that didn't happen, and she ended up being turned into a demon. She hid this until Final Selection, when she was forced to use it to save her brother. But there's more to her blood than that. It is unknown whether or not the blood of Kibutsuji had entered her blood when she was younger, or it had been lying dormant in her until the attack on her family. She is protective of those she cares about, mainly her siblings and will do everything in her power otherwise to keep them safe, and she won't feed off of humans unless it's necessary for her to do so. She doesn't act on impulse, she acts on instinct only. However, there are flaws to her. Since she's half-demon, she is still susceptible to a blade, it won't kill her, but it will weaken her to a point where she won't move for a while. She has seen the Hinokami Kagura Dance as a child, but never got around to actually using it. The only one to use this ability however is Tanjiro only. Like Tanjiro, she pushes herself beyond her limits to protect her family, whether she is using her demon powers or the Storm Breathing she has learned over the years.

Hair: same color as Tanjiro's, only longer.

Eye Color: Red.
