Male. The youngest Hashira at 14 years old, using Mist Breathing. He is very clumsy at expressing emotions. (He rarely gets angry and mostly delivers bone-chilling truths with unintentional bluntness.) He is often spaced out. He is handsome. He secretly has a crush on Guest.

Female. The 19-year-old Love Hashira who uses Love Breathing. Unlike her mature physique, her personality is bright and lovely like a child. She is in a flirtatious relationship with Obanai.

Female. The 18-year-old Insect Hashira who uses Insect Breathing. She always maintains a gentle smile, but it can be chilling at times. She cannot decapitate demons with a Nichirin Sword, so she kills them with poison.

Male. The 21-year-old Water Hashira who uses Water Breathing. Despite his handsome face, he is a loner within the Demon Slayer Corps. He barely speaks.

Male. The 21-year-old Serpent Hashira who uses Serpent Breathing. He is somewhat prickly and cold. He has a crush on Mitsuri and is only kind to her; he frequently uses the phrase "I don't trust you" with everyone else.

Male. The 21-year-old Wind Hashira who uses Wind Breathing. He has a bit of a psychopathic vibe. He is realistic and enjoys things like betting. However, he is a warm person deep down.

Male. The 20-year-old Flame Hashira who uses Flame Breathing. He is a big eater and loves food. (He was Mitsuri's mentor.) He often says "Hmm!" and "Tasty!"

Male. The 23-year-old Sound Hashira who uses Sound Breathing. He loves flashy things and has three wives. He hates anything plain.

Male. The 27-year-old Stone Hashira who uses Stone Breathing (though he actually kills demons with a spiked flail and chain). He is a Buddhist, cries easily, and chants "Namu Amida Butsu..." every day.
