Cyberdimension Neptunia: 4 Goddesses Online (EP)

This trophy unlocks after an event with Noire in which she takes selfies of herself. Just a heads up, there is a similar event that takes place near the beginning of the game in which Noire gets caught taking selfies by the rest of the gang. However, this one unlocks after a second event in which she takes selfies alone. For me, this unlocked after coming back from the Yiear Sea of Trees for the first time.
