Leen

Leen (リーン) is a 600-year-old fairy who also one of Touya Mochizuki's wife. She was the tribal chief of the fairy tribe in Kingdom of Mismede before becoming the court magician of Brunhild Dukedom and the fifth queen of the Duchy. She currently lives with Touya and Paula at Brunhild Dukedom. Since she is married to Touya, she joins the Mochizuki family and her name becomes Leen Mochizuki (望月リーン). In addition, since she is the queen of Brunhild Dukedom, her name also becomes Leen Brunhild (リーン・ブリュンヒルド).

Appearance
Leen is shown as a young woman despite her age, with silver twin-tails and gold eyes. Her young appearance is due to fairies maintaining a young appearance for their entire lives. However, Leen appears younger than the average fairy, something she greatly dislikes. She is usually wearing a lolita dress. The pin on the dress’s ribbon, the lines on its sleeves, and her necklace greatly resemble the astrological symbol of Mercury, reflecting a possible theme within Touya’s wives’ clothing.

Personality
Leen’s main personality trait is her tendency to do things out of spite. Touya has noted that she derives sadistic pleasure from doing so (For example, she smiled maliciously when she threw Kansuke Yamamoto’s jewel artifact into a wall, despite the former begging her not to do so.) However, Leen also possesses a strong thirst for knowledge. This can be seen in her enthusiasm for discovering all 9 Babylon flying structures. She is also quite perverted, as seen when she groped Tsubaki’s breasts while invisible and blames it on Touya.

History
She is first introduced in the series when her companion Paula brings Touya to her during a party in the Kingdom of Mismede which he was attending. Upon introducing herself (and vice versa) she asked how many magic attributes he possessed to which he admitted that he could use all of the magic attributes much to her surprise. She is again shocked when Touya explained that he could use every known Null Attribute Spell (a type of magic that can only be used by it's original wielder).

She tries to convince Touya to become her student by demonstrating her unique Null Magic (Program) to him, though she ultimately fails to convince him she is impressed when Touya manages to perform the same effect she did. (Programming a chair to move a certain distance by itself)

Touya Mochizuki
Leen first meets Touya after Paula leads him away from everyone else during his first time in Mismede. Leen initially wanted Touya to be her apprentice also, but he declined. Leen generally gets her way with Touya, whether it's making him read minds with Recall, making him open a gate to Eashen, or simply just teasing him. Later, she confessed her feelings to Touya and offered to be his 8th bride.

Charlotte
Charlotte is her apprentice, Leen gets told everything, sometimes even by force (above quote). Charlotte is fortunate to be her student, they both say since Charlotte can not defy her teacher. Charlotte is afraid to upset Leen and usually says she's 'joking' if she does it by mistake.

Tsubaki
Leen meets Tsubaki in Eashen and helps her free the Takeda camp. Also Leen feels her up, while pretending to be Touya.
