Having not read any other chapters of the manga and the WN translation cutting off before whatever Vol 6 is adapting, that’s arguably not the weirdest thing Yuuri has done/been involved with. About 500 years after this story she would reincarnate her direct descendant after genderswapping him as his friends (one of whom is also her descendant) daughter, 500 prior to this story she would be raped for 5 years straight destroying a city, an event that would be remembered even a thousand years later, she runs a shop selling OP gear in the home base of a group that actively claims she is worse than hitler (or something to that effect) and much more.
