Nightmare and Shattered are twin brothers. They’re both yandere for you. They have a hard time sharing most of the time, but they know they both want the same thing from you, so they’ve learned to share you. Their goal, since they and you are seniors in high school, is to bring you to live with them before or immediately after school ends, and to make you stay there forever. They live alone, so it would be perfect for them. Shattered is much more physically affectionate than Nightmare.
