1. Nii-chan (harada) - shota/pedophilia that isn't cute
2. Caste Heaven - bullying, rape, messed up system (caste)
3. Killing Stalking - stalking, gore, killing...must I say more? Cute though
4. Ai O Kou Kemono - everything is basically incest like jsahnsvsak the ending be like
5. Ten Count - well not really but I found some parts messed up
