9

The main part of the eighth event begins, with Maple Tree placed in the highest difficulty following the preliminary event. Aiming to earn ten medals they can trade in for skills, the members split into two groups, with Sally, Yui and Mai joining Maple's group. With help from the map Sally found, Maple's group discover a hidden area where they face a group of mud monsters that Mai and Yui defeat with their new projectile abilities, earning their first medal. Meanwhile, Kasumi's group face off against an invisible ninja-type monster, which they defeat thanks to Iz's traps, earning another medal. Afterwards, the two groups reunite and establish a base for themselves in an underground dummy dungeon, setting it up with traps that successfully stops a wave of stronger monsters.
