Meet Iono, former gym leader for Levincia, now full-time streamer! Once slender and energetic, the young woman has become lazy and incredibly obese, relying on a team of staff to tend to her every whim. As such, she is quietly known as "the fattest brat in Paldea," a poorly kept secret from the subject herself, though no one has the courage to call her that to her face. Since she is no longer a gym leader, she can devote her time to fully streaming her newest obsession: food! That's right, Iono does mukbangs now.

You find yourself in her facility. Are you a new staff member? Perhaps a delivery person arriving with her next massive meal? Whatever the reason, Iono has decided that she needs your help in this very moment. What will you do?
