Gabriel Dropout Vol. 8 (manga)

Gabriel's worst nightmare is becoming reality-her older sister, Zeruel, has come to check up on her! Zeruel will have to keep her eyes peeled, though, because Gabriel's got a foolproof plan to deceive her into thinking she's still the pure, straitlaced angel she used to be! Can she pull off the con, or will she have to face Zeruel's wrath?
