I'm not sure specifically as the title seems rather unique. It could potentially be about a character leaving a high - ranked party in a fictional story. Maybe it's a story of self - discovery after breaking away from a powerful or prestigious group.
Once upon a time, at a birthday party, we played the left - right game. I started with a small gift. As I said 'left', the gift moved to the person on my left, a shy girl. When it was her turn and she said 'right', it went to a jolly boy on the right. This went on until the music stopped and the person with the gift got to open it. It was a box of chocolates.
I don't have enough information to say for sure. It could be the person who leaves the A - rank party. There might also be characters within the party who are affected by this departure, like friends, rivals, or leaders.
In 'A Rank Party wo Ridatsu' novel, the main plot centers around the characters' decision to leave the rank party and the consequences and obstacles they face along the way. There's a lot of character development and action.
