Sentouin, Hakenshimasu!

Sentouin Roku-gou is a chief operative of the Kisaragi Corporation, a villainous organization with a mission to conquer the entire known universe. Believing his combat skills are superb, Roku-gou is sent to infiltrate the kingdom of Grace, a mission that could change the world. He is accompanied by Alice Kisaragi, an exceptional android with a youthful appearance named after the company itself.

Upon their arrival, they meet Snow, the commander of the country's royal guard. Snow leads them to a broken legendary artifact, and Roku-gou seizes the opportunity for a promotion and changes the recitation for the sacred ritual to an embarrassing phrase. As punishment, the princess of the kingdom forces Roku-gou to become an honorary knight, infiltrating the kingdom's inner circle.

Now, Roku-gou must help his new employer fight against the Demon Lord's Army, while still performing evil deeds as a combatant of the Kisaragi Corporation.
