In a world where businesses make bank through dungeons and battles, Minato is thrown in charge of a small company by his childhood friend-turned-secretary.

Kibou Company is strapped for cash and their only hope gathers dust in a museum. In order to get it, they'll have to go for broke and compete in a taxing contest.

An arrogant, little wizard by the name of Marika discovers a map which entices the crew on a treasure hunt in search of the most precious treasure of all.

President Minato visits Marika to fetch a form, but then everything goes amiss. There's trouble brewing in Gatepia and it has already claimed a first victim.

Kibou Company explores the strange, new dungeon in hopes of earning enough to obtain the old man's legacy. However, it's a trial for them in more ways than one.

Minato bonds with Guide while tackling a mountain of paperwork. Later, Akari finally opens up to Minato and asks a very embarrassing question.

After hearing rumors about a new species of maju that's able to talk, Makoto is unable to contain his excitement but his actions put the party in danger.

Makoto's newfound friend had a gash on her leg and he's worried what that might mean. Now he's desperate and determined to find Mineko before it's too late.

Minato gets to see a new side of Yutoria when the two of them are talked into exploring a dungeon together. Her fighting skills may be sick, but so is she.
