Start with a Broken Pocket Watch and Watch Me Identify the Gods.

Outside the world, there is endless weirdness. Remains of gods, living knowledge, conceptual weapons... And I am the investigator who handles them. A pocket watch judged to be a [useless]-level containment item. Noisy and venomous, but able to see through all disguises and whisper the truth of all things. "Why are you so cowardly? This guy was beaten three thousand years ago. His weak point is the third tentacle on the left, wrap it around!" "Don't touch that book. If you turn a page, one of your organs will be missing. Quick, burn it on fire and give it to me as a midnight snack!" Contain, identify, devour... In this world full of lies and taboos, I will use it to reveal all the truth!
