Ukei Kaito fought a desperate struggle in order to fulfill his role as a summoned hero. He defeated the Demon Lord and saved the very world, only to meet an end filled but with betrayal. The companions that he’d trusted throughout his journey betrayed him and killed him by sticking a blade through his chest.

Gilderoy Lockhart has just become Minister for Magic of the United Kingdom, and there are several uninvited guests in the office.

Dumbledore: “Minister, I have to tell you with great sadness that Moriarty Slytherin is the most hidden person in the European wizarding world!”

Lovegood, editor-in-chief of The Quibbler: “Look Minister, the Hogwarts Riots, the Himalayan Avalanche, the Gringotts Heist, the World Cup Opening, the Nurmengard Bombing, the Azkaban Defection , the Durmstrang riot, these mysteries all point to one person, Moriarty Slytherin!”

Platinum noble Lucius: “On behalf of the pure blood family, I strongly request the minister to launch a wanted request for Moriarty Slytherin! Oh, my minister, don’t look at me with greedy eyes, all pure blood money is taken by Mori Artie’s gone.”

Gilderoy Lockhart showed his signature smile: “Please allow me to introduce to you my young master, the greatest wizard of all time, the master of dawn and darkness, the master of ice and thunder, the legendary god of magic, Moriarty Slytherin!”

This is the story of a little wizard who only has magic in his heart and becomes the big boss behind the scenes in the Harry Potter world.

However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.
