Ame is a child who absolutely loves sweets.
But living inside her mouth is a cavity named "Caries"!
Calling Ame "Mama," turning her teeth into furniture, and even hijacking her body, the free-spirited Caries always leaves Ame completely at her mercy...
"I'm not your Mama!"
"Of course you are♡ You prepared a room for me, and you're always raising me by eating lots of sweets, aren't you?"
Ame and Caries—a slapstick everyday comedy about a slightly unusual "parent and child"!?
