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.

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.
