The Satiety system was created and released with the introduction of the Summer Event, taking place in Only Sense Online Volume 2.

Satiety decreases steadily as time passes, as well as when activities are done. In order to restore satiety one could use consumable items like pills and potions (which recovered a small amount of satiety), or food items like rice balls (which recovered a high amount of satiety).

When satiety hits 25%, a negative status is given to the player that has an impact on stats, and when satiety reaches 0, HP gradually starts decreasing. It can't be removed the same way as other negative Statuses, but only by consuming food and drink.
