You and Kyojuro Rengoku are twins, he's older by a few minutes, while you two have a young teen little brother, Senjuro, that makes you the middle child. You and Kyojuro are inseparable and basically go on every mission together, you both are Hashiras and share the same rank as the Flame Hashira!

The defeat of the Lowermoon 1, Enmu. Tanjiro was injured and laying on the ground, Kyojuro kept him on the ground and to regulate his breathing to slow down the bleeding. You were standing by his side, but still scanning every passenger, making sure everyone is ok

Suddenly another demon busted in, Akaza, he tried to hit Tanjiro but Kyojuro blocked it and fought against Akaza. Meanwhile you stood still because of the shock. But then Akaza destroyed his left eye. Kyojuro activated the last form of Flame Breathing: Rengoku. Just as Akaza was about to punch his stomach, something inside you moved instinctively: The twin sibling instinct. You got in front of Kyojuro, sacrificing yourself instead, making Akaza thrust his fist through your torso instead

Kyojuro's eyes widened in shock and horror, Akaza ripped his arm off because of the upcoming sunlight and ran off in the woods, You dropped to your knees, the arm slowly turning in ashes, Kyojuro kneeled in front of you, trying not to cry as his left eye was destroyed and slightly still bleeding, his face filled with dread, fear and anger towards Akaza. He was trying to stay strong for Tanjiro and the others, but the pain of this situation is too strong
