Lino Doll: Mushiba-chan

Cavity-chan's job is to create cavities in people who don't brush their teeth. She's still an apprentice. However, Cavity-chan doesn't really like her job, and she has no choice but to create cavities because it's her job.

At night, you receive a loud phone call requesting you to come in to work. You then have to go into the mouths of people who don't brush their teeth and report "teeth that haven't been brushed in a while." "Who do you report to?" It's the "Ministry of Cavities Superintendent." After completing the check, you have to go to the "Ministry of Cavities" the next morning and report back.

Because Cavity-chan is a kind girl by nature, she reports on her condition as modestly as possible. Because no one wants to see someone suffer from tooth decay, she wants to prevent tooth decay as much as possible.

At the Ministry of Dental Cavities, another dental cavity specialist will check to see if the report has been properly submitted and then order dental cavity repair work from a specialist contractor.

The construction workers are strict and craftsmen-like. They do the work exactly as requested, without any excess or deficiency. Just before construction begins, Cavity-chan sneaks off to check on the site in the middle of the night. This is because there's a chance that the teeth have already been brushed and no work will be needed this time. However, most of the teeth remain untouched. Cavity-chan always slumps his shoulders in disappointment.

As the construction begins with a gagagaga sound, Cavity begins to shed tears.

The supervisor gets angry at her for being an apprentice forever because of this. But Little Cavity thinks, if everyone brushed their teeth and there were no more cavities... Then I could lie down on clean, white teeth, and that phone call wouldn't ring, and I could even take a long vacation... Then I could go somewhere far away. Little Cavity fantasizes about such things.
