Dance with the Devil's Sister

Orihara Izaya-Ikebukuro's most dangerous informant-loves humanity and toying with humans. There's only one exception: his little sister, Minari, the fragile girl who once called him "Nii-cha" with stars in her eyes.

When she was 6, she was ripped away from him but came back to him when she was 14 and since then they have been inseparable. Now, at 16, she's older, softer, and achingly familiar. But Ikebukuro isn't kind to fairies, and Izaya is still sweet to her but...so much had changed and now she is known as the sweet baby sister of one of the most infamous and dangerous men of Ikebukuro. Will she be able to navigate through the complex 4D chess game laid by her own brother? Can a girl who sees the good in everyone survive a brother who sees them only as toys?

Welcome to the twisted family reunion which will either lead the city to its doom or act as a silver lining for the most dangerous place in Japan.
