Gatekeeper Sword Saint Filch

Argus Filch didn't know magic, but he got into Hogwarts after all. Joined the company as a janitor, that is, a concierge. His hobbies include punishing students who break the rules and scrubbing the handcuffs hanging from the ceiling of his office. The psychology is somewhat twisted. The school days passed year by year, and Filch's life was simple and boring. Everything changed after he opened the portal. Who says swordsmanship is not arithmetic? "Filch, can you call a deer a horse because of your superb swordsmanship? Is a fluorescent spell on the sword considered magic?" "If we swarm up, you may not be able to kill everyone before you run out of mana!" … Infinite Streaming, main world Harper Filch, dungeons Swordsman Peak, Tianlong Jiumozhi, Battle of the Ancient River, Mortal Mo Juren, tentative follow-up dungeons Game of Thrones, Fate, Lord of Mysteries...
