I Have Zero Otaku Knowledge, But I Somehow Ended Up Enjoying Otaku Activities with A Gyaru Who Hates Men

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—!?
