Clean Freak in the Dirty Age: Isekai Sanitizer

Kazuki Tanaka, a 23-year-old obsessive clean freak, dies after slipping on a soap bar in his pristine bathroom. Upon awakening, he finds himself summoned to a medieval fantasy world known for war, plague, and most of all — filth.

Magic exists, but only destructive spells are valued. That is... until Kazuki discovers his unique "Sanitation Magic" — the power to clean anything, from physical dirt to curses and corruption. With his enchanted mop and a divine disinfectant spell, he becomes the world's most feared purifier.

Armed with a modern mind and an OCD-level obsession for hygiene, Kazuki sets out to cleanse not only grime but the rotten hearts of tyrants, monsters, and a continent drowning in chaos.

Join him on a squeaky-clean rampage in a filthy, magic-infested world!
