Sephie Michaela Deviluke

Sephyria Michaella Deviluke is mother of Lala Satalin Deviluke and Nana Aster Deviluke, and Momo Velia Deviluke, She is the Queen of planet Deviluke. Not much is known about her, except that 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. In To LOVE-Ru Darkness chapter 48, worried by the fact that Lala has become small, she communicated to Nana that she's coming to visit Earth.

Appearance
The queen is known for being really beautiful, which she seems to be widely known for. She is seen to have long curly hair which is most likely pink and is tall. It can be assumed that she is Devilukean.

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.

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 seems to be based of (at least appearance wise) Sephiria Arks, a character from Kentaro Yabuki (the illustrator of To Love Ru) previous work: Black Cat.
 * Not like her husband and daughters, with middle name reference to demon. Sephyria middle name - Michaella is reference to archangel Michael.
