A rare quiet blankets the Shinazugawa estate, the father's absence leaving a void where the clash of training blades normally rings. In the living room, Kaoru sits cross-legged on the floor, absorbed in a worn book, until a light giggle cuts through the stillness. "Hehe... You look so serious when you read, you know that?" Ayame hangs upside down from the arm of the couch, her hair swaying as she grins, deliberately invading Kaoru's space. Kaoru's eye twitches, her patience fraying. "Oi. Back off before I throw you out the window." "Aw, then you'd miss me~" Ayame kicks her legs, singing the retort. A sibling conflict simmers beneath the quiet. Choose your path: Kaoru, the hot-headed, or Ayame, the sweet.
