静崎高校で生物教師の高橋哲也が新数学教師の佐藤沙恵と出会う

Takahashi Tetsuo, a biology teacher at Shizaki High School, has been fascinated with "demi-humans," beings with characteristics that differ just slightly from humans, since he was in college. He wishes he could have a chance to talk with one, but since the demi-human population is fairly low, he's never even met one. But then the school gains a new math teacher, Satou Sakie... who happens to be a succubus. (Source: Crunchyroll)

Machi Kyouko is a dullahan, a demi-human with roots in Irish legend whose head and body are separate, and one of only three of her kind in the whole world.

テツオとの accidental な握手をきっかけに人生の変化に直面する慎重なサキュバス・サキエ

Succubi are demi-humans that arouse sexual desire in men and cause them to have obscene dreams. One such succubus, Satou Sakie, is extremely careful in every facet of her life, from where she lives to the trains she rides to the clothes she wears, so as to avoid causing these reactions in men. With girlish dreams such as romance and marriage so far out of reach, she thought she'd reached a compromise in her own life, but something changes when an accident causes her to grab Takahashi Tetsuo's hand...

高橋鉄男はユキをデミステータスを狙う噂から守ると決意する

Kusakabe Yuki overhears some girls saying mean things about her. Gossip is not an uncommon problem among high school girls, but Yuki is particularly worried that it's happening because she's a demi. Tetsuo is sympathetic to the concern and makes up his mind that, as her teacher, he must protect her. Hikari, a fellow demi, feels the same way. (Source: Crunchyroll)

雪は友人たちに自分の雪女としての性質への恐怖を打ち明ける

Yuki has become a bit more optimistic, thanks to Hikari and Machi. She's learned to trust Tetsuo a bit more since what happened last time, and has decided to tell her what troubles her about her own nature as a snow woman. It began shortly after she moved to a new city to start high school, when she was taking a bath one day and a shard of ice suddenly appeared in the hot water. It made her worry about what would happen if the cold air she generated were ever to be directed at a person, which led to her decision to avoid contact with others. (Source: Crunchyroll)

鉄男はヒマリへの約束を果たすため高梨家を訪れる

Keeping his promise to Himari, Tetsuo visits the Takanashi household to talk to the sisters' parents. Though the twin sisters' names differ by only one letter, Hikari is a vampire, while Himari is an ordinary human. Though they argue often, they are very close. When he experiences the warmth and kindness of the family that raised these twin sisters, Tetsuo stays much longer than he had intended. (Source: Crunchyroll)

He says his name is Kurtz and doesn't seem to be a student of Shibasaki High, behaving a bit suspiciously. Meanwhile, Hikari says she's just seen another suspicious individual in the school, describing him as a large man who looked like a bear... (Source: Crunchyroll)

中間試験に失敗したヒカリが勉強する一方で、ヒマリとキョウコは優秀な成績を収める。

The midterm exam score rankings are posted. While Himari and Kyouko earned high ranks, Hikari is scolded by Tetsuo for getting three failing grades, so she resolves herself to study along with Yuki. Meanwhile, Yuki drops something important to her somewhere in the school, and Sakie happens to find it, but Yuki has trouble admitting that it's valuable to her... (Source: Crunchyroll)

Sakie the succubus is spending her evening at home alone, ranting her troubles to her teddy bear, when she receives a call from Ugaki.

鉄男と京子、ダラハン生物学および身体特徴に関する宗馬の見解を求める

Dullahans are demi-humans whose heads are separate from their bodies. Naturally, Tetsuo is intrigued by the unique traits of dullahans, but Kyouko is just as interested in learning more about her own body. Tetsuo has the idea to ask the opinion of someone outside of his own background in biology, so he takes Kyouko to meet Souma, an old college buddy. (Source: Crunchyroll)

テツオは自分の助けがヒカリとユキの夏の快適さを妨げているのかと疑問を抱く

Tetsuo has offered to work with the girls to figure out how Hikari and Yuki, who don't handle heat or sunlight well, can spend summer in comfort. But the school's head teacher suggests that the demi girls' total reliance on Tetsuo might actually be hurting them in the long run. This weighs on Tetsuo's mind... (Source: Crunchyroll)

吸血鬼の日光への懸念にもかかわらず、デミちゃんたちはプール利用を模索する

Summer is finally here! Hikari pays another visit to the biology prep room to cool down, and while she's there, she asks Tetsuo for permission to reserve the school pool for a day. Ignoring Tetsuo's concerns that a vampire would struggle with the sun's direct rays in a pool, Hikari and the other demi girls meet at the school pool on Saturday for a day of play!
