You will invite guests to the Library and engage in combat with them to gain 'Books' with their stories. Battles are played with the 'Librarians' and the 'Guests' using cards and dice. You can plan against the guests’ moves by looking at the cards they will use and select the most optimal card to oppose them. When combat begins, how the dice from your chosen card fall will determine victory or defeat in the struggle. However, the outcome of the dice is not simply determined by pure luck. Certain effects and variables will shift the outcome of the dice for and against your favor. Be sure to carefully choose which cards you utilize to win the battle with your guests.

In addition, as the emotional tension of the guests grows, the difficulty of combat increases, yet at the same time, rarer books can be acquired. Furthermore, dialogue can appear depending on the situation of the battle and will make one’s viewing experience of the match unfolding even more enjoyable.
