Isekai'd Into the Wrong Timeline

Y/N thought joking about getting isekai'd into Kalego Gaiden was harmless-until the universe apparently took it personally.

Now stuck in Babyls as a fake archival assistant with a suspicious system giving quests, they have to survive demon school politics, hide the fact that they're human, and avoid wrecking the timeline.

Unfortunately, young Naberius Kalego already thinks something about them is off, and he's exactly the wrong person to get suspicious.
