Even if the brother is in love, it’s no problem, right

Due to family reasons, Akito Himokoji (voiced by Ryota Aisaka) and Akiko Himokoji (voiced by Kido Ibuki), brothers and sisters who have been separated since childhood, are about to live under the same roof again. What Akito, who makes a living by writing forbidden novels, did not expect is that his sister, the once innocent and lovely Akiko, has now become a brother-controller! Sure enough, Qiuzi, who advocates "the love between brothers and sisters is a precious and pure emotion", launched a fierce attack on Qiu Ren. A group of beautiful and beautiful girls gathered around Qiu Ren, which made Qiu Zi feel like she was facing a formidable enemy. Nasuhara Anna (voiced by Minori Chihara), a tsundere girl with golden twin tails who always talks about pornographic topics inexplicably; Haruomi Saruwatari Ginbei (voiced by Asami Shimoda), who is weak on the surface but has a sinister heart; and Nikaido Arashi (voiced by Eri Kitamura), who has a fiery personality but is very reliable. Their existence adds fuel to Akito's already chaotic life. And Qiu Ren, who always rejects Qiuzi based on blood relationship, hides a shocking secret - there is actually no blood relationship between him and Qiuzi.
