A woman with blue hair and a crown to boot, she has an "E" marked in the top left corner of her torso. Her clothing is made of pebbles, but official artwork shows her wearing a more elegant outfit. She appears at almost every single shop in the game and is also present in the The Guardian in Ten Mou, selling you items to buy for Studs. Eunoia has sparse dialogue; only ever talking when you interact with her cash register or when you interact with the coffee machine at Ten-Mou.
