Histoire

A girl who is "the world's everything", meaning she possesses all of the world's knowledge and has the ability to reshape reality. Though she does have limitations herself, such as not being able to do much other then look up information unless given permission by others.

Histoire is a quiet girl with a sense of justice. She looks to be no older then Gust, but is very powerful and strong. She is also very knowledgeable, but it can take her days on end just to find the right information she needs...

Usually Histoire is happy or joyful, and often peppers her words with emoticons. She seems to lack a temper and has a very gentle voice, although in the Manga she does have just a bit of a temper, kicking out Neptune, Blanc, and Vert from their current living locations due to not taking their roles of Goddesses responsibly.

She also loses her temper and lashes out at Neptune and Nepgear in the prologue chapter of Hyperdimension Neptunia V after having tolerated both sisters' laziness for too long.
