蒼の刻印～BLUE TEMPEST～

Boys all over the country yearn to join Saint Sirius' Knights and Saint Capella's Knights. Alf, who wants to be a knight, traveled to the Holy City from the country in order to take the test to become a knight which is held once a year. But he's had a childlike face since birth and is small, so he's turned away at the door. The tests begin while he disputes it with reception, and just when he doesn't know what he's going to do one of the leaders of the knights calls over to him. Wanting to become a knight by any means possible, he's told that if he helps the five leaders with their official duties and improves his skills under them, they will add him in the next year's test.
