  Summary

  Fourteen-year-old Ranpo Edogawa opens the door of Fukuzawa’s house to find a ginormous man outside. The man invites him to Hogwarts and he uses his deduction skills from there. Learning and weaving his way out and in to trouble, chowing on sweets and chips all at the same time.

  This work is inspired by Allegory_for_hatred’s ‘Magic & Mystery’ and ‘Coil’ books, which are inserting Dazai into the Harry Potter universe. This book will be similar, but as Ranpo instead Dazai. I hope you all enjoy reading this.
