Hogwarts: the Snake Yard Boss Starts by Collecting Rent

Alan traveled to the world of Harry Potter and discovered that the ancestral shop in Knockturn Alley had been robbed of rent by a dark wizard. As the only heir of the Alderton family, the angry Allen obtained the rent-collecting system for everything! "Your letter allowed the Auror to capture the absconding werewolf, the information was successfully rented, and the Wandless Iron Armor Curse was harvested." "You answered Hermione's question and gained the first place in the exam." "You help Luna feed the unicorn and gain immunity from the curse." "..." Snape: What! Two transfer students named Sister Ka came here? Dumbledore: Allen is either doing good things or on the way to doing good things. The Lord of Death is just a rumor! Allen: I'm just a rent collector passing by. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
