Momo Deviluke is a smart girl. She is almost as smart as her sister, a galactically recognized genius inventor. The third princess to the Deviluken Empire is smart in a political way. She seems to understand people, sometimes better than they understand themselves. She then uses that information to help her achieve her goals, which in many cases will make all parties involved happier.

For proof, we just have to look at the “Harem Plan.” Momo’s sister Lala loves Rito and wants to marry him. Rito is in love with Haruna and also loves Lala. Momo loves Rito too and still wants her sister to be happy. How can she find a way for all parties to be happy? Her first step is to get transferred to Rito’s high school and away from her tutors in the palace on Deviluke. There she will be able to keep an eye on Rito and the women in his life. Second, make Rito a man’s man that wants a harem to begin with. Rito is kind of a meek boy who would never make the first move. Momo arranges romantic situations with more than a half-dozen girls in Rito’s life. Momo is playing the long game, putting the pieces into motion that will lead to Rito being put into a position where a harem as the king of the galaxy will be the best option. It’ll also get Rito to reciprocate her love.

We look at Momo and think “why can’t a girl that cute be in love with me?” The third princess of the galaxy is a girl of average height in the anime world at about 5 feet tall. Her bust is, in our opinion, a happy medium between Lala’s large bust and Nana’s nonexistent one. She has large purple eyes and short pink hair she keeps pinned out of her face with a flower barrette. The “sensitive” Deviluken tail that swings behind her ending in a spade that pokes out from under her skirt always attracts the eyes. The way she twists her hair around her fingers when she is deep in thought is absolutely adorable.

She always makes sure she dresses the part, too. Momo tends to choose short skirts and long knee socks creating excellent Zettai ryoki. She also tends to choose blouses with scoop or plunging necklines. Momo has been known to wear the naked apron in her never-ending quest to seduce Rito.

We’ve all heard talking to plants is a great way to help them grow and that goes double for Momo. The power to talk to and command plants is a unique ability to the Deviluken princess. She with the help of her D-Dial, a phone-like device Lala created, she can summon hundreds of plant friends she’s collected from throughout the galaxy.

In spite of her age, Momo is an expert xenobotanist and horticulturist. She understands the chemistry of every one of the plants she has stored in the D-Dial. She’s the one who understood the effects of the love-pollen that had every one chasing Rito through town. Momo’s control over plants works well in combat; she summons thorny rose like plants with teeth to ensnare several of the male students when they were under the control of Nemesis. The irony of her love for vegetation is that she is trying to turn Rito into a carnivore kind of man that’s more aggressive toward the girls in his life and her.

Momo has a bit of a naughty streak. She seems to be a bit more mature than her sisters even though she is the youngest. Momo understands that using sexuality is just one of the ways she can get what she wants. She also seems to seek out the chances to be closer and more intimate with Rito.

Momo spends a lot of time in Rito’s bed. She slips into his room in the middle of the night in the hopes that Rito will get grabby in his sleep. She also has been known to get lost in her day dreams about the “Harem Plan” and what she’d like Rito to do to her. The day dreams often leave her just standing there with a smile and drool on her face. We even know she plays eroge from when she tried to explain the birds and the bees to her ever-innocent older sister Lala using a video game. She didn’t get too far though, stopping at the idea of kissing as she wasn’t willing to corrupt Lala too much.

For all her calculation, seduction, and occasional selfishness, Momo is kind. Momo is always willing to help others even if it means going out of her way to do so. The “Harem Plan” she came up with is predicated on the idea that she was willing to share Rito with all the women in his life. She’s even willing to be his concubine if he were to marry Lala and Haruna.

We see some of this kindness in episode 1 of To LOVE Ru Darkness when she is seen sneaking into Rito’s bath and explaining the reason for the “Harem Plan” is to make all the girls happy. She also makes a big effort to bring the assassin Golden Darkness into the fold by befriending her. Momo can even be a good sister to her older twin Nana. Despite teasing her sister about her less-than-developed bust, Momo has made efforts to cheer her sister up when she was feeling down after Nana’s friend Mea became distant.
