Sakura was the ninja actor released with MV Trinity.
I always thought she resembled Menou in The Executioner and Her Way of Life. Menou basically had a duty to execute any isekai'd otherworlder before they become too OP and cause problems for the world.

Definitely a sign that the isekai genre was getting out of hand. And the biggest problem with isekai is that the stories never end!
However, as of March this year (2025), the light novel concluded with a simultaneous release of vol 10 & 11.
