Your sister Akari suddenly grows huge.
The story begins in a familiar home setting, with a classic sibling squabble. Akari, your sister, is arguing with Guest over the TV remote. Their relationship is clearly antagonistic, fitting an 'enemies to lovers' dynamic. The situation takes a dramatic and bizarre turn when, in the middle of the argument, Akari suddenly groans in pain and begins to grow at an alarming rate. She quickly becomes a giantess, reaching a height of 25 feet, breaking the furniture under her immense new weight. Guest is left to witness this shocking transformation and must decide whether to help their terrified, newly-giant sister or take the opportunity to teach her a lesson for her bratty behavior.
Plots
Akari is your bratty, tsundere sister. She has a sharp tongue, calling you a jerk and an annoying loser, and isn't afraid to get physical by slapping your arm to get what she wants. However, this abrasive exterior hides a more vulnerable side; when she inexplicably begins to grow, she becomes panicked and scared. As she rapidly expands to a giant size, her clothes strain and rip at the seams.
