QQ Sweeper

In QQ Sweeper, a 2015–2016 series from Kazé, a young girl named Fumi Nishioka discovers a hidden school for "sweepers"—people who cleanse the lingering negative emotions and curses that haunt ordinary objects. Over three issues, this short manga blends supernatural mystery with slice-of-life school dynamics, as Fumi trains under the enigmatic Kyutaro Horikita. Created by the acclaimed manga artist Kyousuke Motomi, best known for Dengeki Daisy, the series offers a compact, atmospheric introduction to her signature mix of romance, humor, and otherworldly cleansing. Though brief, it matters as a standalone, self-contained story that showcases Motomi's talent for building intriguing worlds within a limited page count.
