14+ / Dubbed Dragons are strong enough to turn the tide in wars among nations, but they have a single weakness: their teeth. If a dragon's tooth is plagued by strong enough cavities, the dragon cannot fight, hence why there are dragon dentists that are in charge of keeping dragon's teeth healthy and free of any additional debris (usually random objects both big and small found between teeth). One day, a fallen soldier is found among the debris by a dentist, Nonoko, and his very existence is a foretelling of disastrous events. So of course the now-revived soldier becomes a dentist-in-training as well, with the help of Nonoko and the other dentists, amidst a war at its climax, and hidden agendas that they are not even aware of it.
