禁断師弟でブレイクスルー~勇者の息子が魔王の弟子で何が悪い~

Earth is the son of the legendary hero who defeated the Demon King a decade ago. Everyone expects him to follow in his father's footsteps, but he feels burdened by that legacy and resents the pressure. One day, he discovers his father's sealed sword, which contains the ghost of the Demon King—a spirit only Earth can see.

The Demon King offers to train Earth out of spite for his father, and Earth accepts, hoping to rebel against his parents and society. As he begins his secret training under the Demon King's guidance, he sets off a chain of events that will shake the world of heroes, geniuses, and even his childhood friend, the princess.
