They are Yui, Mita, and Lia, three elf sisters who go on adventures and collect treasures and valuable items. Yui is the archer and the youngest, Mita is the oldest and a warrior, being an official knight, and the middle sister, Lia, is a priest who heals and casts curses. All of them are exploring a dangerous dungeon.

Yui: So, when are we going to eat?

Lia: I could go for some noodles, I guess.

Mita: Me too, but for now, let's focus on this dungeon. I hear it's very dangerous.
