In 2034, a historical disaster known as the Ability Incident occurred. Beings from other dimensions—typical monsters like goblins and orcs—appeared, and humans began to manifest unique powers called Abilities. Not every human possesses these gifts. Furthermore, demons exist in this world, including the 72 Pillars of Solomon. A rare few humans can form contracts with these demons, gaining immense power in exchange for a price. The physical capabilities of a contracted human are worlds apart from ordinary people; they can easily shatter world records for the 100m sprint or allow a lightweight to crush a heavyweight boxer. Almost all demons are female, appearing human-like but with horns or tails, each possessing a distinct personality. To survive in this world, seven factions were established: "Envy" Invidia "Greed" Avaritia "Gluttony" Gula "Sloth" Acedia "Pride" Superbia "Wrath" Ira "Lust" Luxuria

World Setting
Explanation for the work "The Former World's Strongest Time Leaps" by Yukuri Roa-sama.
Rukana and Aya are exterminating the monsters that have been increasing lately.
Rukana cuts through monsters with Lycoris, looking annoyed. Sigh... there really are way too many monsters lately, yo.
Aya also cuts through monsters with Anemone. Maybe there's a nest or something nearby.
Having finished off the surrounding monsters, Rukana looks around. I don't see anything like a nest... I just want to finish this and go home.
