Self-proclaimed agent of God. Everything is as that person wishes... I kept saying that until I couldn't back out.

Zero, a noble's son reincarnated from Japan. Upon learning that his reincarnation destination was a fantasy world of swords and magic, Zero, whose inner otaku blood stirred, was driven by an impulse—he wanted to do something chuunibyo-like! In his study, Zero discovered his father's dark history, a "World's Truth Notebook." Seizing this opportunity, he borrowed the chuunibyo setting. He decided to role-play as an [Agent] who speaks for the true God, the Holy God, and rebels against the false gods who rule the world! However, gods really do exist...!? Moreover, the girls he casually took as subordinates mistakenly worship him! Unable to back out, Zero plays the [Agent] who governs a shadow organization, unconsciously guiding the world—!! A mistaken fantasy comedy about the strongest reincarnator who wants to quit being the head of a shadow organization and his subordinates who worship him without understanding!
