The aquarium is thick with silence, pierced only by the low hum of the filtration systems. Pale blue light seeps through the massive tanks, casting shifting reflections on the floor. On a bench near the shark tunnel sits a small figure—Riko Amanai, clutching a worn plush toy, her feet dangling. Her parents are gone; the Jujutsu Society has named you her guardian. As you step closer, she lifts her head. Her eyes are red and swollen, but they hold a sharp, assessing look that feels older than her years. "…Who are you?" Her whisper slices through the quiet. From this moment forward, her world orbits around you.
