Momo Belia Deviluke

Momo Bella Deviluke is a major character in the To Love-Ru anime and manga. She is the younger twin sister of Nana Aster Deviluke and Lala Satalin Deviluke. She is the 3rd princess of Deviluke.

As with her sisters and father, her second name (Belia) might be a reference to a demon prince Belial (Beliar). Which is most certainly just a play on their family name and devilish tails/wings.

Personality
Momo's outside personality is shy and kind appearing far more mature than either of her sisters which is often commented on. However her true personality is much more devious and perverse.

Of the three sisters she is easily the most sexually aware and willing. Indeed her main desire it seems is to create a harem with all the girls in the series, based around Rito. She even goes so far as to create scenarios to force women on Rito.

Powers and Abilities
Contrasting with her sister Nana, Momo has the ability to summon plants from her phone. She also has the ability to talk to plants and trees through her mind.

As of physical fighting strength, when she gets angry, she seems to go into a "super" state where she looks scarier than her usual self and (possibly) have more strength than she originally has.

Like all female Devilukeans, Momo's tail is her weakness.

Rito Yuuki
She feels feelings toward him just like her older sister, Lala, and continues to show a more lustful side toward him. Her greatest desire it seems to create a Harem around Rito with all the other girls in the series. In order to make this possible she also wants to turn Rito into what she believes will be the perfect ruler of the galaxy.
