Two or Three Things About Time Travel in Comprehensive Comics

It's been a long time since I watched the anime. Anyway, I saw it when I was in school. I probably still remember the plot. The male protagonist was bought by his parents. The school is full of monsters. The male protagonist is a human. He seems to be a harem question. The welfare is slowly increasing. The male protagonist seems to be called Xingye or something. Anyway, this is the first harem anime I have seen.

Finally, someone is writing an old story. Keep it up, but it's best not to be the best in one world, but to be able to travel through time, otherwise the combat power will be easily lost.

Why is no one talking? Isn't it funny?

The first volume is very good, but the following two volumes are confusing, a little unclear, and very confusing, and I have no desire to read further. I hope the rest of the series will be the same as the first volume, and don't be a Riddler.
