Heroine? Saint? No, I'm an All-Works Maid (And Proud of It)!

Luciana and the others were looking at the results of the test that had been held the other day. On the posted ranking list, Luciana's name was listed as third in the grade. Luciana was happy that she and Luna had achieved top grades in the class. That rank should have been where the heroine was supposed to be. However, now that the heroine hasn't appeared, Annemarie begins to think that perhaps Luciana is taking on that role instead. Meanwhile, Olivia was watching the happy Luciana and the others with a cold gaze...

Maika, who has started working for the Rutleberg family, immediately recognizes Melody as the game's heroine. In fact, Maika is also a reincarnated person with memories of her past life. Up until now, she had relied on her knowledge of the game to get by. However, upon arriving at the Rutleberg family's home, she learns for the first time that the scenario has changed. While Maika is confused, Melody is thrilled to be called "senpai" for the first time. Meanwhile, at the academy, a series of incidents involving vandalism in classrooms begin to occur, and an ominous atmosphere starts to permeate the air.

Melody and the others try to cheer up Luciana, who is feeling down after being suspected of vandalizing the classroom. Maika, thinking that her game knowledge might be useful, suggests that she also go to the academy to investigate the case. When they arrive at the academy, the love interests have personalities that are different from those in the game, and they seem as if they have already been conquered... While they continue their investigation despite being confused by the differences, Luciana is being accused by the students of a crime she did not commit, namely splashing water on Annemarie.
