In a gritty, dystopian world, Eridan is tired of living in the slums and longs for a chance to change his fate. After a conversation with the shopkeeper Hans, he learns about the mysterious and perilous fractures—chaotic realms where individuals can access unique abilities called specialties that manipulate time and space. However, these powers come at a significant risk, including the possibility of becoming trapped forever. Determined to escape his bleak existence, Eridan resolves to step into a fracture, but first, he must secure a fracture key, undergo rigorous training, and find allies to support him. Despite Hans's warnings about the dangers of the fractures, Eridan's fierce determination ignites hope within him as he sets out on a quest to challenge his fate and prove his worth against the odds.
