Xdrrrwhat's Wrong with Being a Younger Brother?

[Female disguised as a man + Invincible + Comprehensive Headless East + Sin Song Matrix + Information Dealer] [The heroine disguises herself as a man and will not be discovered before the ending + she is called Ni-chan + is not a good person (Ikebukuro-style yandere)] Chun got the surname Hui Gu at the age of fourteen, along with two younger brothers. In her opinion, these were just small pleasures in her life. "It's not interesting, but it's not boring either?" Haitani Tsubaki said to Orihara Izaya who looked like he was enjoying the show. The person she hates the most is Yagiri Namie. That woman always talks about her younger brother, which is annoying to death. Is it really necessary for such a thing as family to exist? Until—— "My brother is simply an angel! He is pure and kind, and he is so cute!!" Everyone: Are you blind? How do those two guys have anything to do with angels? So the largest underground intelligence organization ruling Roppongi was established hastily. —————— Orihara Izaya's biggest hobby is observing humans. In his words, humans LOVE! Except for his only female friend Haitani Chun. Since the other party bought a handful of sin songs without wanting to be a human being, he has fallen out of the category of human beings in his eyes, and now he has developed into a pervert. "How come Ran-chan and Xiao Gentian are so cute~ Even if they shave off their heads, they can't hide their beauty. I can't imagine how we can live without our cute brothers and sisters! Why don't the three of us get married together! Ah... By the way, thirteen is not yet the age for marriage, well, what does it matter~" Orihara Izaya listened to his friend's daily seizures and silently pressed the alarm call. If your ears are stained, then I'll give you some trouble~
