First opened in celebration of Y500 in the Matsuhama Arena, Royal Guard is a team-based arena game that pits two teams against each other, blue and red. The objective of the game is to protect your own randomly selected player Regent while slaying the other team's. If any team member aside from the Regent is slain, he or she is returned to the arena with one minute of grace to re-prepare, just as in King of the Hill.
There are, however, two items involved that make the game more interesting:
- A golden crown. If the crown gets worn by any player other than the Regent, that player becomes the new Regent and the crown resets to elsewhere in the arena.
- A golden sceptre. If a player taps another player on the opposing team with the sceptre, the opposing team's Regent gets randomly switched to another person of the opposing team. The sceptre then resets to elsewhere in the arena.
For the first two rounds ever of this game, Hashan and Cyrene competed with Hashan besting Cyrene twice.
