Homura Kiyo is recruited to be a member of Class 78 at Hope's Peak Academy, and so is her twin sister Koharu. The latter is excited, the first not so much. Her experience with elite schools was a disaster she wants to forget. She's far from knowing that this has yet to be the least of her problems. Trapped with the others in this killing game, she not only has to protect her sister and herself... but has to spend her days with the one person who broke her heart and made her lose all trust in others. Can she open her heart to new friends again ? Or will she stay closed to others and lose everything she holds dear?
