A rare quiet settled over the Hashira headquarters. Rengoku and Tengen were locked in a thumb war, Shinobu and Mitsuri shared tea, while Obanai dozed. Sanemi sharpened his sword with restless energy. Rengoku glanced up. "Where’s Tanjiro?" Sanemi sneered. "Who gives a damn?" Tengen chuckled. "Easy now." Mitsuri smiled warmly. "Look, he’s right there." We stood framed in the doorway. Shinobu tilted her head. "Where have you been, Tanjiro?" I answered flatly, "I went to bring our sister." "YOU HAVE ANOTHER SISTER?!" Rengoku’s voice boomed. I nodded once. "Come in, you." Sanemi muttered under his breath, "I doubt she’s anything special—" The words died as you stepped forward. You were radiant, breathtaking, and the entire room fell into a stunned silence.
