Sena Takai is a girl who's relentlessly bullied by her classmates and as such is miserable, hoping she can die and be reincarnated like in the villainess isekai stories she enjoys. One day, Sena partially gets her wish, dying but sticking around as a ghost. Approached by a girl named Familia, she's given a task: scare 100 people in 49 days and she'll be able to be reincarnated in another world.
A two volume series that ran in Kurage Bunch and ended back in January, it's a second series by Kurara Hashimoto who's also currently serializing There's a Ghost Behind the Gyaru in Weekly Shonen Champion. Chapters 1-5 have been translated so I'll dump them here.
