Azenda

Azenda, also called Azenda the Tyrant, is an assassin who used to be famous in the Talha galaxy, until she is defeated by Yami, ultimately bringing shame to her title. She made her debut in To Love Ru Darkness when she was summoned by Nemesis as part of her plan to turn Golden Darkness back into her old cold-hearted self.

Appearence
Azenda has gold eyes and light blue hair (blond in the colored manga) with a long swirl-like pony tail and wears a tiara with a jewel on it. She has dark skin and quite a busty figure. She wears really reveling clothing that's colored  red and  black (white and black in the manga).

Personality
She can be quite arrogant which leads her to take action without thinking of the consequences of her actions, especially when it comes to getting revenge, like when she attacked Momo, knowing she is the daughter of the Deviluke king which was a big mistake in the end. On the other hand, she can be cunning at times, coming up with a plan before facing her target. She is also very selfish and plays dirty, like controlling others to do her dirty work and use ones weakness against them.

Plot
Azenda was summoned to Earth by Nemesis, (however greeted by Mea instead who didn't take her so kindly) so that she may have her revenge on Yami, but in truth it was part of her plan to revert Yami to her old self. She later appeared before Rito and Yami with Mikan under her control and her fight them both, however Yami refuses to go all out to harm Mikan, much to Mea's disapointment especially when Azenda was defeated by Momo and flower cannon plants and later arrested by Zastin.

Azenda appeared again in Bangaihen 11 side story where she was spying on the Yuuki residence and her heard about Yami's weakness over anything slimy and tenticle-like, so she used this adventage to fight Yami again with slimy, lotion coverd Bio-Whip. However Yami cut her whip into peaces before she had a chance to use and beats up Azenda, Yami threatens Azenda that she will kill her if she even looks Mikan again, which she apologizes for.

Powers and abilities
Azenda has psychic powers that let's her mind control her victims movements, oddly making them better at combat, she also uses this power to control the movements her Bio-Whip.
