I'm terrible at writing blurbs, so please check out the story!
The worlds of Jujutsu Kaisen and Bungo Stray Dogs accidentally merged. To keep the worlds from collapsing, they joined forces to create a "daughter" and entrusted her to Edogawa Ranpo's parents, so she could grow up alongside Ranpo. As the combined embodiment of both worlds' powers, Jiang Xingnai possesses both an ability and cursed techniques.
At 14, Gojo Satoru spotted her and invited her to Jujutsu High. From then on, she repeatedly turned everyone's expectations upside down.
After seeing what she looked like:
Everyone at Jujutsu High: White hair and blue eyes. Could she be Gojo Satoru's sister?
After seeing her cursed technique:
Everyone at Jujutsu High: Ten Shadows Technique??? From the Zenin clan? But what's with that pig that only knows how to swear? Is that thing one of the Ten Shadows shikigami?
After discovering her true personality:
Everyone at Jujutsu High: Aaaah! What happened to the lively, cute, energetic girl? Who is this deranged demon with a twisted sense of humor!
At 18, she graduated from Jujutsu High and joined the Armed Detective Agency.
Jiang Xingnai: Onii-chan~ Here's your allowance for the month: 100 million yen. Keep it safe, okay? But if you lose it, no big deal. Just come ask me for more~
Oda Sakunosuke silently put away his planner, filled with discount deals because he had to raise five kids.
One day, the president went out with the two of them.
When he saw the girl sit down on a bench by the roadside and immediately find herself surrounded by cats, none of which left even when he approached, he silently held out the dried fish hidden in his sleeve.
1. There will be deaths, one-sided crushes, and a little bit of a harem vibe.
2. The heroine is obsessed with Ranpo and possessive. Don't read if that's not your thing.
3. Ranpo is the love interest, and that will never change. Childhood friends.
Note: I may rewrite this.
