CPU arrives in Arodie Cavern in order to complete a quest for an ingredient to weaken the final Sacred Treasure boss.
Blanc notes in order to get the ingredient, they need to clear this quest first. Rom worries that this is hard. Blanc assures her that all they need to do is get the items and report to the guild. It shouldn't take much time. Ram thinks that is easy and says she will find them all. Blanc warns her that there are strong monsters in this dungeon so they shouldn't let their guard down.
Later in the dungeon, Rom wonders where the item is. Ram wants her sister to compete with her to get the items as a game. Blanc warns the two that it is dangerous and asks that they don't run too far ahead. Rom and Ram agree.
Ram hears a weird noise. Rom worries as she hears the noise and her screen is weird. Blanc does not hear anything on her end. Perhaps it has something to do with the connection. She asks Neptune if anything is wrong on her end. Neptune has no problems and thinks the two are imagining it.
After collecting all the items for the quest, Nepgear reports that it is done. Rom smiles as that was easy. Ram agrees and all they have to do is report to the guild. Neptune is glad as a bonus that they are all still in good condition.
