Welcome to the university where bunch of privileged kids enjoy their time living in a bubble. Are you like me who has enough disapproval and hypocrisy playing around her hands? Meet Hino Keren, a young woman of 20 years old admitted to an international sectarian school - also known as Saint Lourdes International University, an institution planted somewhere in Nagasaki. Keren is angry, Keren is always in rage. She wanted to bring a galon of kerosene just so she can pour it to these privileged kids' Mazda cars or their Veyrons. Keren hates men. And Keren mainly hates Morimoto Yu because—well, just because. But indifference is a change that stacks with interest. One can only wonder what makes Keren interesting.
