Mischa

Mischa is a Person of the Land, the granddaughter of Fedor, and twin sister of Ivan.

Like Ivan, Mischa is original to the anime and was not present in the light novel version of the scene.

Appearance
Mischa has light brown hair and dark brown eyes. She resembles Minori, just as Ivan resembles Tohya, which makes Shiroe think of them when he lays eyes on the Lander twins.

Prior to the Catastrophe
Mischa and Ivan were born during a blizzard. Fedor, as the only man in the house while their father was away doing business, had to carry their mother to the doctor on the other side of the mountain so that she could deliver the twins.

Return to Akihabara
During a thunderstorm, Shiroe's Party arrives at Arb and is invited to stay in Mischa's family's barn by their grandfather. Mischa and Ivan are awestruck by the ninja-like Assassin Akatsuki, asking her to show them some of her techniques. The group later gives the twins and their grandfather some food as a token of their gratitude, including cookies, which fascinates them.

The Scale Festival
Fedor, Mischa, and Ivan make a brief appearance in this episode, partaking in the revelries of the Libra Festival.

Trivia

 * She shares her Japanese voice actress with Minori.
 * Even though Mischa and Ivan are supposed to be twins according to the episode they debuted, later tweets by Elissa claimed Ivan's birthday is on September 3 while Mischa's is on October 1.
