For the summer heat, some chilling horror (jk)

A comedy using perverted themes. Mainly between brother and sister.

A lonely "demon lord" and a self-centered "hero"!?

What about "villager A," caught in the middle!?

This is a school that prepares people for roles in fantasy stories. However, those who possess the "traits" of a "warrior" or "wizard" are but a few. Most will become no more than mere "villagers." I, Satou, am also one of those "villagers"; but one day, a girl possessing the trait of "demon lord," Ryuugamine Ouko, set her eyes on me. She's short and a surprisingly calm, good girl, but she'll abruptly mutter about destroying mankind; give me a break. Taking up the opposition with passion is my childhood friend, Hikarigaoka Tsubasa; she's more trouble. This girl is also quite the beauty, but as soon as she makes up her mind, she's an absolute troublemaker...

This is a world that's slightly abnormal, with a slightly abnormal cast, interwoven in their dilemmas; a slapstick comedy!

"Twins" - Two children that develop in the same womb and are born at the same time, Even though we were raised in the same environment, even though... "When we were born, Hinata took even my portion of the nutrients... Those nutrients, I don't mind giving them back to you, Haru?"

In another world, the skill I was bequeathed was――"Summon Kitchen"? Eh, what the heck is that?!

The Office Lady that got mixed up in a high school girl's summons to another word―Isarai Shiina.
Unlike the warm welcome given to the high school Saintess, Shiina is forced to live in a corner of the royal palace with her mysterious and newly obtained "Summon Kitchen" skill.
Apparently, using the skill to cook food amasses points, which can then be used to evolve the "kitchen".
'With nothing better to do, and things being what they are, I might as well work towards getting my glorious dream kitchen!' but, despite her enthusiasm, Shiina was told to keep the contents of her skill a secret by her guardian knight, Hurst...

(Or- What is the identity of the silver-haired man?!) Furthermore, the mysterious sentient ivy serving him. In the cruel emperor's era. A love story revolving around two people in a gentle fantasy world!
