In Hentai World as Mira Tsubakihara's Relative

After transmigrating, Hikari quickly discovered that this so-called "2D world" was not quite the way he expected. There was no Shuchiin Academy, no Service Club, no Yukino, no Eriri... Instead, he found himself in a strange and dangerous world that made less and less sense the longer he stayed. For now, Hikari was living at Miss Mira's house. As if that wasn't already strange enough, Mira's best friend happened to be Mrs. Kasumi. The apartment next door was home to a silver-haired beauty who looked just like a real-life Yuki-onna. There were also sunflowers, hydrangeas, and countless other mysteries he couldn't explain. His class representative was named Chizuru. His homeroom teacher was Miwa Shirakawa. And for some reason, the three gyaru girls in his class wanted to hold parties at his house every single day. Then there was Sakurajima Miyajima, the head of the Kendo Club; Nanao Akane, the Baseball Club manager; and the two sisters from the Archery Club with the surname Sakuramiya. And right next to his school was the prestigious Sekai Girls' Academy. Things only became stranger when he discovered that he had countryside relatives named Kaiseiri and Sayoko, while his neighbor was a NEET who proudly called himself a "self-defense force." This world was completely chaotic. Danger was everywhere, and one wrong step could drag him into some bizarre situation—or something much worse. "This world may be filled with corruption and absurdity, but I'll destroy it all with one punch." —Nakamura Hikari, the Pure Love Battle God.
