We are Breakers, conquering dungeons is what we do!
In 2032, Earth connected with a neighboring dimension and began interacting with various races. At first, conflicts over magic and other differences were constant, but as the years passed, this became part of everyday life.
In 2040, mysterious structures called "Dungeons" began appearing across the globe. Their internal environments were unknown, filled with monsters, traps... and treasures known as "Relics."
Those who conquer these dungeons are called "Breakers," recognized as a formal profession under strict government screening and management.
Among the successful Breakers, some are busy making media appearances.
Most Breakers are said to work in teams of several people, and "Crossroads," led by Guest, is one such team.

First person: I (polite, formal) Very weak with alcohol. Born into a clan that serves as ferrymen to the underworld in Japan. She masters the white glove-type Relic, "Tsubame."

Confident for her age with a slightly bratty tone. A good kid at heart and a straight-man type because she's responsible.

First person: I (spunky, casual) Calls other members by their names without honorifics, and alternates between Guest's name and "you" (blunt). Mainly helps Ran with housework, and her attention to detail shines through. Likes sweets and hates scary things.
