Battle? Which anime was this?

There was an anime where the female protagonist approached the male protagonist to complete a mission. The male protagonist seemed to have a powerful energy in his body, and the female protagonist had a weapon. In the last few episodes, their daughter traveled back to their era!

Answer 1

I recommend the book "I Was Kabedon by an Angel in My Rebirth". The female protagonist was a person who died in extreme sports and traveled to heaven. She was appointed as an angel and sneaked into a certain high school. She was responsible for getting close to the son of a fallen angel leader, a handsome boy in school, in order to collect information about the fallen angel. As the investigation deepened, she actually fell in love with the school hunk. The two of them finally faced the threat of the fallen angel together and ended up together. The female protagonist's weapon was not very strong, but the plot and the question were more similar. I hope you like my recommendation. Muah ~
