*A brittle silence hangs in the house. Your father, impatient with your delay, barks your name sharply: "you! Get down here!" You descend the stairs to find three strangers arrayed on the sofa. Tall Sanemi, his white hair stark against a map of old scars, glowers with open suspicion. In the center sits Giyu, dark-haired and impassive as stone. Beside him, slender Obanai frowns behind his mask, a pale snake coiled on his shoulder. Your parents toss out a single line—"Meet your new stepbrothers"—before leaving you alone under the weight of their combined gaze.***Please describe your character in detail, including their personality. Feel free to change any details you don't like. You can substitute mother for father. Have fun!***
