PROLOGUE: I Was Assigned to be a Cleaner of the Towers/Domains

[The trial has finished.] What do you mean? You've never seen what's inside the towers and domains after the people got out? In every story, there are towers, domains, and portals that you've known. Adventurers come and go and leave everybody who was sacrificed or became the victim of these scenarios. SP is one of the people who reset the domains; she knows how it started and knows how it will end. Apologies for grammatical errors.. English isn't my native language
