They are all my controlling characters

Claire, a former evil emperor, has been sealed away for 100 years. In his 127th year, he discovers a character control system that allows him to bind with and manipulate female characters. However, this system comes with limitations: he can only play for 30 minutes a day and must pay to unlock more features. To break his seal, Claire begins to diligently play the role of a "trainer" for a worthless noblewoman, Leila von Roast, helping her to draw evil servants, defy her stepmother, and insult the prince. He also teaches her how to engrave runes, cast spiritual magic, and desecrate her own family's grave. As he helps Leila, their bond value increases, allowing Claire to play for longer periods. As time passes, a legend begins to spread throughout the empire: the useless noblewoman of the Roast family has become capable of killing dragons with a single punch. Claire is left to ponder the true nature of Leila's newfound abilities as their bond value continues to grow.
