Nana Astar Deviluke

Nana Astar Deviluke is the twin of Momo and sister to Lala. She is the second princess of Deviluke. She has the ability to speak to and understand animals. She argues with her sister Momo a lot but they always make up afterwards. She doesn't like Rito because she thinks he is a perverted beast. Although we do see her try to sleep in bed with Rito after he had saved her from falling. In To-Love-ru Darkness Nana, along with her sister, become Sainan High's students, she makes friends with a girl named Mea and she gets shocked whenever Mea admits something perverted to Rito. Eventually, the friendship between Mea and Nana becomes very strong; however, Mea turns into her semi-weapon form and tells Nana that their friendship was not real! Nana was petrified and tramatized after she saw Mea's true form and personality. Rito tried to console Nana. When that didn't technically work, Rito embraced Nana. With that hug alone, Nana finally realized what she had to do. She had to approach Mea and "open her heart". Obviously, Mea used her semi-weapon abilities to scare off Nana again; however, Nana has shown a huge amount of courage and she faced the heartless semi-weapon. Nana stood there boldly and she confessed her care for Mea. This somehow opened Mea up. Finally, Mea understood what a friend truly was. This part of the story has shown Nana's bold bravery against something quite deadly, and this has shown Nana starting to open up to Rito. In fact, she even tried to sleep in Rito's bed once. It's only a matter of time until Nana finally confesses her true feelings to Rito Yuuki.

Thanks to Nana's insane outbursts about Rito being a "beast", the entire female cast is starting to "unconsiously" have sexual interests in Rito. Of course, they are NOT consciously aware of this. Mea is clearly the exception to the rule as she's clearly admitting her sexual desires to Rito. Lala, Haruna, Momo, Yui, Yami, Mikan, and Run are part of Nana's "Harem Plan"? Yes, it turns out that even though Nana is trying desperately to keep the other girls away from Rito, she's only indirectly creating her own unification of the entire female cast. Are Saki, Rin, Mea and even Dr. Tearju taken under consideration? Indeed, eventually, Nana's own efforts will help form the "Harem Plan". Ironically, Nana is counsciously trying to do the complete opposite.
