Dragon Girl - Manga

From Yen Press: An all-boys high school goes co-ed, and though the boys are excited to have girls in their midst, they’re still a little wary about the girls horning in on previously all-male territory. But fiesty, fierce Rinna Aizome won’t take no for an answer; as the daughter of the school’s most legendary ouendan (cheerleading squad) member, she’s determined to show the boys and her father that anything they can do, she can do better! But the road to the ouendan is full of hurdles…can Rinna clear them all?
