Synopsis

The protagonist receives an elixir from a mysterious woman, who reveals her true goal was not the elixir, but to form a contract where she will mentor him. She calls him her disciple and states he will need to prove himself by reaching the 50th floor of the dungeon before they continue. He later encounters members of the Iron Guild and a powerful maze boss who are both out to kill him. Finally, two seemingly random people who have also been giving him elixirs revealed themselves to be helpers.
