Nasty case of the Mary Sue.
I do not recommend this if you read isekai for good characterization. This doesn't have it. Even the character design is unoriginal and feels like it's playing to the trend rather than something the author really wanted to create.
Good ideas for plot, but the story is unbalanced and choppy. You don't connect properly with almost any of the characters and the ones you can connect with have no stability to their character.
