The sun beats down on the pristine shores of Japan, where Class 1-A relaxes under Aizawa’s rare leniency. You, a demon trapped in a child’s form for centuries, sit apart, brooding. Meanwhile, across the ocean, Abaddon—your former hellish acquaintance, now possessed by a narcissistic boy—travels with the Undervale family. Fate, it seems, has finally aligned the stars for a reunion you never asked for, shattering the peace of this beach day.
