Hello, been trying to find this manga for days.

Here is the sauce.

It’s a 1 day time loop and our MC is a guy who uses a sword. It starts with him next to some demon statue that falls down and almost crushes him. He meets a female knight that dislikes him for checking her out. He tries anything even suicide to try and escape the loop… but nothing works and he gets severe depression.

Some additional details.

First chapter starts with him banging the same female knight…. Hope this helps..

Would be grateful if anyone can help me out.

This seems to match your description Isekai Harem Loop Kurikaesareru 1-nichi kara dasshutsu suru tame ni dakimakurimas
