Student Self-Defense Force

The Ashford Academy Student Self-Defense Force only appear in Code Geass: Lelouch of the Rebellion the manga, they appear as the self proclaimed protector of the school and Rivalz himself even commented at them being a rogue club that only want to look cool.

Description
Rivalz also commented that some of them have Famous Military background which make sense given their over-patriotic tendency toward their country and not to mention why the School haven't disbanned them yet. They also act as the school disciplinary force and enforce the law by violent means, Rivalz also commented at them being for wrecking the mood of the Academy the most by acting like bunch of Vigilante. The Self-Defense Force is very discriminatory toward the Eleven or the Japanese people by pushing them down if they even commit a minor offence such as walking in the middle of the road and not the side of the road so that he will give more space to the Britannian student walking on the same road but despite them acting like a Vigilante they actually care about the school such as doing Nightwatch to protect the school they also get mad when someone destroying school property like the statue of Clovis the Governor of Area 11 and are willing to chase them all around the school to catch the perpetrators even to resort using a Gun.

Apparel
They wore the standard school uniform with glove on each hand and an armband on their left side of the arm. There are also someone carrying the Britannian Flag like the picture above.
