Fujiwara Asako became a spiritual examiner because she was interesting.
From now on, Asako Fujiwara: Hot chicken current affairs ruined my youth.
It's probably a variety manga. There are three that I'm thinking of right now, including Fumino, Natsume, and Gintama.
The heroine has traveled through many worlds, can travel through space by herself, and has high combat effectiveness.
Ps. The author loves the protagonist who is beautiful and strong (and can turn dark at any time), so the heroine's appearance is definitely amazing, but she wears a jade pendant that can make her look a little ordinary.
Pps. There may be very few plots in comics that travel back in time, and the author may also write extremely OOC. This is not self-effacing, it is true.
