Nature	Insomnia
Episodes	Magia Record Game, Episode 2

The witch of sheep. Her nature is insomnia. This Witch is scared of everything. Not knowing what to do, she stays within a fence in her Labyrinth. Being so wary, she has grown many eyes. There is no moment, neither day or night, that she closes all of her eyes at the same time, which means she does not sleep. She has never gone outside of her fence, and never will. She sees herself as her Familiars' pet and waits inside her fence for them to hunt humans to feed her. She looks so meek because she seems scared, but when one of her Familiars is defeated, she becomes filled with panic and goes on a rampage.

Minions

結界の周りを散策するようにゆっくりと歩いている手下。魔女の飼い主のつもりでいる手下たちは、魔女を大切な財産だと思っている。普段は魔女の様子を見守る他、結界内へ迷い込んだ人間を見つけて、首から下げた角笛を吹き鳴らし、遠くの手下達に合図を送ることで集団で狩りをしている。とは言え、大人しい羊の魔女一匹に刻して羊飼いが大量に居る状態であるため人間が来ない限りはあまりやることもなく暇を持て余している。羊飼いとしての仕事より手下同士で今年のチーズの出来具合を話している時間の方が多い。

Episodes	Magia Record Game, Episode 2

Minions of the witch of sheep. Their role is to be shepherds. These Familiars stroll leisurely about their Labyrinth. They regard themselves as shepherds of their most precious possession: their Witch. Normally they simply watch over her, but when they see a stray human in their Labyrinth, they signal each other using the horns that hang around their necks. Once they have gathered, their hunt begins. Since there are so many of them taking care of the meek Sheep Witch, they do not have much to do other than hunt humans. They have too much time on their hands, so they spend a lot of their days talking about the quality of this year's cheese.
