On this episode, our male lead plays a game with a princess.
Whoa, they revealed the main plot and it looks very interesting. Although it's definitely similar to the Mondaiji-tachi ga Isekai Kara Kuru So Desu yo? series. Anyway, the brother and his sister are just awesome and they also revealed one of the antagonists who is currently bullying the princess. Overall, I am no longer having my doubts and will be looking forward for the next episode.
Conclusion: The main plot got revealed and it looks interesting.
