Twinkle Saber Nova(2004)

Twinkle Saber Nova

"Justice is within your heart!"
Welcome to the Misaki Academy, a futuristic island-sized school where students' freedom is valued above all else. This lack of restrictions has lead to the founding of some very unusual extracurricular activities and groups, like the World Domination Club. When the World Domination Club attempt to control the school lunch program, cute high school girl Hayana Suzunari decides to take a stand, becoming Twinkle Saber, defender of justice!
The series that took the amateur press manga industry by storm is now widely available as "Twinkle Saber NOVA"!

Alternative Summery:
Hayana and Aoi go to Misaki Academy, where their favorite pastime is to eat at all the local restaurants. Misaki is known for it's lax importance on rules, and while that means freedom, it can mean trouble. Hayana's lunch gets interrupted one day by a new club... the World Domination Club! (They're starting with the school lunch program and working outwards.) Luckily, Hayana gets some help from one of her teachers and joins the Ally of Justice Club as Twinkle Saber, sworn to defend the lunchtime (and truth and justice along the way) of Misaki Academy against the World Domination Club!
