Hana Kamado - eldest of the Kamado siblings, Yoriichi's descendant, and bearer of a curse written in blood and fire. She was born to shield, to burn bright where darkness crept in. Giyu Tomioka - the Water Hashira who found his quiet in her light. This is not only Tanjiro's story. It's hers - the sun between the shadows. And his - the one who stood beside her.

Breanna, an army Sergeant, has never been the easiest to get along with and has struggled to get close to people due to some past traumas. With a chip on her shoulder, Breanna ensured that everyone is kept at arms distance. She's been able to stand her ground and hold her own against everyone she's encountered. That was until she received a special request from Captain John Price to accompany Task Force 141 on a highly dangerous and classified mission. Without knowing why she's being requested, and because her curiosity got the better of her, Breanna accepted the invitation to work alongside the Task Force. Breanna's life gets turned upside down when she's forced to work side by side with the infamous "Ghost". Ghost is unlike anyone she's ever met before, but at the same time uncomfortably similar to her own self. Through bickering and butting heads, Breanna and Ghost have to find a way to work together without compromising the mission. And over time, things between them start to...change. A type of change they never imagined.
