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!
