Ria remembered her mission which was hectic, she felt so stuffed for eating an ice monster and a wind monster hence feeling sick to death about eating such elements which contained different elemental substances, "That was the day I never ate for a month, Dia." Ria was with Dia in a hidden location, it was like the two are killing sometime before revealing themselves or at least go back to the guild hall, it's odd for Ria to be slacking this days but ever since she ate two monsters, it's understandable for her to be slacking and not doing anything for long periods of time, she's on the path of recovery.
