Nana Asta Deviluke
has long hair, a single visible sharp tooth and unlike her sisters, a flat chest. She is quite jealous of Momo's chest. Spoiler!She understands and can talk to animals. At some point of the series To Love Ru OVA 5, Nana develops small feelings for Rito, after he saved her from Momo's plant friends. And she manages to get the courage to sleep with Rito in his bedroom while he is sleeping, but actually sees Lala and Momo sleeping with him.
Nana is so far the only character to question why so many girls fall in love with Rito, yet it is clear that she has growing feelings for him as well.
Like her sisters, she has a cell phone capable of transporting objects. However, instead of gadgets, Nana summons animals.
