Sephie Michaela Deviluke

Sephie Michaela Deviluke is mother of Lala Satalin Deviluke and Nana Aster Deviluke, and Momo Velia Deviluke, She is the Queen of planet Deviluke and a decendent of an alien race known as Charmians.

In To LOVE-Ru Darkness chapter 49, worried by the fact that Lala has become small, she has come to visit Earth and to know Rito.

Appearance
The queen is known for being really beautiful, which she seems to be widely known for, She covers her face with a veil so that men don't get affected by her ability. She is seen to have long curly hair which is most likely pink and is tall.

Personality
She acts more as the leader of the planet Deviluke than her husband, Gid Lucione Deviluke, the king of Deviluke. Unlike her demanding and spoiled husband, she has been described as a wonderful person, a hardworking leader of her people, and a good role model for her daughters. As the current queen of Deviluke (in the king's place, who isn't good at politics), she demonstrates active leadership and endeavors to maintain relations with every planet.

Powers and Abilities
Sephie is part of a race known as Charmians, who are endowed with the most beautiful voices and appearances in the Universe.
 * Charismatic voice: Not only does Sephie have a beautiful voice, she also uses it to bring out the good in people and stop conflicts between them using only her words.
 * Lust Inducement: Charmians are considered to be the most attractive race, although because of this, anyone of the opposite gender so much as looks at her face will turn into a sexual beast no matter how much of a gentlemen he is, This works on all forms of life.

Gid Lucione Deviluke
She is married to Gid, the king of Deviluke and the emperor of the Milky Way galaxy. It's unknown what her impression of him is, especially considering his intentions of dropping down from the throne to go around and do perverted things to other women, but Momo states that Gid is completely unable to oppose her. It was Gid, however, who saved her when the great intergalactic war was fought over her.

Daughters
Not much is known about the mother of Lala, Nana and Momo. It's said that she is a very beautiful woman, and that Lala, Momo, and Nana have inherited her beauty, but Nana likely does not share their impressive breast size, much to her dismay. Momo states that she's a wonderful person. To her daughters, she is the person they admire the most.

Despite their love for her, Lala and her sisters do not seem too lonely or upset at being so separated from their mother while staying on Earth. Because their mother is so busy leading her people (and because of their father's perverted hobbies), her daughters seem to have grown up most of their lives in the palace under the care of Zastin and their teachers.

While on Earth, Momo has stated that despite being busy most of the time, their mother still makes time to call them (To-Love-Ru Darkness Chapter 23).

Trivia

 * In chapter 2 of "To Love Ru Trouble", a mistranslation stated that Lala's mother was dead, which caused some controversy when she was mentioned again in Darkness chapter 23, where Momo states she is alive and calls on occasion. She makes her first appearance in person in To Love-Ru Darkness chapter 49.
 * She seems to be based on (at least appearance-wise) Sephiria Arks, a character from previous work, Black Cat, also by Kentaro Yabuki.
 * Unlike her husband and daughters, whose middle names reference to demons, Sephie's middle name, Michaella, is a reference to the archangel Michael.
