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…

I have a massive crush on my classmate, Takase Narumi. My dream is for her to become friends with my shy, introverted twin sister, Kotomi, too, so that we can all live happy ever after in the same class. However, there's one problem: Takase’s best friend, Momoi Maho, a blonde half-Japanese gyaru and online celebrity, who is a beautiful girl, but also famous for hating boys. She treats me coldly, too, but I was hoping she can at least get along with my sister… One day, my sister asks me for a favor. She's nervous about meeting her online game waifu in person and she wants me to go in her place. I agreed to help her out, but to my surprise, the person waiting for me at the meetup was none other than Momoi Maho—!? (Source: Dash Bunko, translated)
