QQ Sweeper

In this short 2015–2017 Tokyopop series, a high school girl stumbles into a mysterious after-school job cleaning up the "dust" of human emotions from abandoned places. The three-issue run introduces a supernatural premise where sweeping isn't just about tidiness, but about purging lingering psychic residue. Though brief, the title is notable for pairing a classic shoujo school-life setup with a quirky, ghost-adjacent cleaning premise.
