Why is My Second Dimension Time Travel to the Main God Space?

I got a system that can travel through the world of the second dimension.

I guess I will live a boring life from now on, punching Ayanokouji and kicking the great teacher, and having a harem of beautiful girls like Yukino Suzune.

"Not bad, you have the best physical fitness among the people who came this time."

Wait a minute!

System, what are you doing?

Is this still the second dimension?

What does the main god space mean? Who can make up for the beautiful girls I lack?

What? The system can replace the horror movie arranged by the main god with anime?

That's fine.

Hehe, I must survive.
