Knowing that both, are not yet assigned to an agency, the third year student Nemuri informs them that if they are looking to do work studies, her boss, His Purple Highness, is willing to take on anyone.
Both accepted Nemuri's invitation, and they start working at the Purple Revolution Agency, under the orders of Purple Highness. His first job was to stop Robber Villain. Although the criminal managed to escape the first time, Shota and Oboro managed to capture him the second time.
