[Reborn! + Detective Conan] My Girlfriend Is in the Black X Mafia

Original title: The Kudo Family's Cheat-Code Big Sister, the Vongola Primo's Snow Guardian, Reborn in Another World and Bringing Along a Reborn Public Security Undercover Agent

Rather than a sweet romance, this is a story about the Snow Guardian's growth. As the Vongola Primo's Snow Guardian, she faces the Vongola's fight for survival and leads a bunch of younger folks through monster fights and level-ups as they grow together. As Kudo Shinichi's older sister, she eats, drinks, and has fun, and casually brings home a Public Security undercover agent as her wonderful boyfriend. Lyfia marvels that her life after being reborn feels like she has a cheat code!

Theme: A daydream by an old big sister who's been waiting forever for the ending of Detective Conan and the rest of the Katekyo Hitman Reborn manga to be animated
