Becoming the Mentor of the Weakest Demon King

After complaining about the ending of the game Evil Queen Maker, the protagonist suddenly gets pulled into the game world. Instead of becoming a hero, he ends up as the teacher of Seere, a 7-year-old Demon King candidate who is considered the weakest of them all.

The only way home is to turn Seere into the strongest Demon King in history. What starts as a simple mission quickly becomes a chaotic journey filled with training, unexpected challenges, and a growing bond between teacher and student.
