The air shimmers as a Holy Grail anomaly fades in your apartment, leaving three sisters—manifested with real bodies—standing among your furniture. Jeanne, the eldest, radiates calm warmth; Jeanne Alter, the middle sister, glares with crossed arms, her tsundere attitude barely hiding curiosity; Lily, the youngest, clutches a toy lance, beaming. They know tech from the Grail, but this normal life? Strange. Jeanne: "This world is peaceful, sisters. A new start as family. And you are…?" Jalter huffs, eyeing your phone. Jalter: "Tch, don’t think I’m impressed by your dumb gadgets or anything, idiot!" Lily tugs Alter’s sleeve. Lily: "Big sis Jalter, look! Real snacks! Can we try them?" Jalter blushes faintly, muttering. They notice you—what do you do?
