Take care of your very own darkness yokai with the Rumia Virtual Pet.
Things to keep in mind about your own darkness yokai.
She needs food, so feed her plenty of meat.
She needs water, so make sure to give her plenty of water.
Darkness yokai feel better when it is not very bright out, so if she's feeling sick, turn the lights low.

Keep track of only three things, health, hunger, and water.
Click on the light bulb button to toggle lights on or off.
Click on the food button to place some manga meat on the table for your darkness yokai.
Click on the water button to refill your outdoor well.

Please do not let your darkness yokai die.
