Can the Young Master Naoya Be a Sister-Obsessed Brother, Too?

After Qianshi died, she was reborn into the top family in the world of jujutsu, as the twin sister of the Zenin heir. Twins were considered an ill omen. She was viewed as a useless burden who threatened the heir’s succession. Soon after she was born, she survived several assassination attempts before being thrown into the cursed spirit chamber to fend for herself. The good news: She had once been an incredibly powerful jujutsu sorcerer, praised by the world as someone who could “rival the gods.” The bad news: She had lost all her memories, along with her cursed energy and technique. Now she was alone, weak, and helpless. By chance, there was another child with no cursed energy locked in the cursed spirit chamber. He had extraordinary talent, but because he couldn’t become a sorcerer, his clan members abused and bullied him. Just as she was about to be eaten by a curse, a boy named Toji saved her life. After that, the clan head spared her life, but locked her away in a remote courtyard and forbade her from taking a single step outside. · When he was six, the Zenin clan’s handsome, arrogant young master heard that he had a twin sister, a useless girl with no cursed energy. With the intention of “destroying her if she disappointed me,” he barged into her cage to meet her. The bad news: The heir had a terrible personality and was shallow about looks. The good news: She happened to have a pretty face that looked just like his. [What the Zenin clan members say] Toji: “She saved my life.” Megumi: “Auntie gets hurt if you take your eyes off her for a second. She’s such a handful, but she’s a good person.” Maki & Mai: “Big Sister is gentle and strong. She’s practically an angel.” 5t5: “Seriously? You’re all being serious? This kid’s got the worst personality ever. He’s such a massive sadist that even I can’t stand him!” The Hei and Kukuru Unit members strongly agreed. Naoya (smiling): “Who cares? She’s cute, and that’s all that matters.” [Reader advisory] 1. Happy ending. 2. Updates daily. [Synopsis for an upcoming story] You inherited the Zenin clan’s ancestral technique, while the main family’s heir did not. So the clan members sent you to him, hoping the two of you would have a more useful heir. When you first met, you sat quietly on the tatami, while he paced around the room in agitation. “Insane,” “legitimate and illegitimate,” “rank and status,” “absolutely not”... After cursing everyone in the Zenin clan from top to bottom, he sat down, out of breath, and picked up his tea. You got straight to the point. “The clan head said he wants us to have a child as soon as possible. When should we begin?” “Pfft! Cough, cough, cough.” Naoya stared at you in disbelief. His skin flushed faintly with embarrassment and anger, and he looked like he wanted to curse you out. But in the end, all he did was purse his lips and coldly say, “Shameless,” before turning and leaving. · When you met again, he had not only been poisoned, but was also cornered in an alley by a group of people. After cutting the others down, you crouched in front of him and looked into his pale golden eyes, clouded with tears. “Can we do something shameless now?” A question mark appeared over his head. His chest heaved as he started cursing again. “Wretched scum,” “useless teammates,” “rotten jujutsu world,” “crazy woman”... You waited patiently. Thankfully, this time he didn’t curse for long before going quiet. Sweat dripped down his face, which was so flushed it looked ready to start smoking. His teeth were clenched, as if he were holding back a moan. He glared at you furiously. Naoya: “...” You: “...” You: “May I?” Naoya: “Y-You idiot.” Theme: If you don’t understand the ugly, evil side of humanity, you can’t love humanity.
