Koitou Ranma ~Watashi ga, Anata o, Mamoru Kara!!!~

The Sumeragi Gakuen is under attack from 5 other schools who are after its enormous wealth. The school’s battle representative Biryuu is on the verge of falling when our hero Miyabi appears and somehow helps her recover. She tells him that he has the ‘sun element’. The goal is to unite the schools and end all the battling.
