On Planet Deviluke, females' tails are far more sensitive than males'.
Lala Satalin Deviluke (ララ･サタリン・デビルーク/ Rara Satarin Debirūku) is the main female protagonist of To-Love Ru and Motto To-Love-Ru, but takes a more minor role in To-Love-Ru Darkness. When someone touches Lala's tail, she becomes weak and seems to lose her strength, though she can shake anyone off of her tail with her astonishing strength.
