To make matters worse, her summoner is the cruel and ruthless villainess, Lapis Tenebrae, who seeks to ensnare various characters within the game. In this dire situation, Midori, who has been deeply immersed in the game, uses her knowledge to avert the crises that Lapis is about to face, claiming it as a form of foresight. This leads to Lapis taking a liking to her (?), and she ends up working as Lapis's personal secretary...!?
