The World of Otome Games is Tough for Mobs

The MC's sister reincarnated in Marie.
What sister? The past life or his new life?
(Yes, both are bad sisters, poor mc  ) 

Also, why do the girls behave so badly in school? What was the reason that women get the upper hand to the point of ridiculousness? 

By the saintess girl you mean noelle right?? Or is it some new character?? Also is the novel in the last volume?? Cause I saw in novelupdate that they only have 4 volumes I think.. 

Hey so what’s the deal with the Noel girl and her younger sister may even be a a reincarnator? What about the other reincarnator that’s in the Kingdom’s school and targeting Olivia? 

You know what? Marie reminds me of the “Bitch of Buchanwald” she manipulates situations and people to make other people’s lives miserable. I wonder if she gets what’s coming to her? 

It is true lul,  in the ln so far it hasn't happened , but it will eventually 

I have some questions about the web novel.

1. Is the web novel still ongoing or finished?
2. With whom does the mc end up?
3. Did the sister of the mc receive a punishment for her actions?
4. Who became the Saint, Olivia or Marie?
5. What happened with the five idiots?
6. Why did his sister Marie behave like this?
7. Did the Mc really lose erverything ( money/power) ?
8. Did the Mc really travel to a new country to fight a new war?

Sorry if I made some mistakes, English isn´t my native language. Thank you for answering my questions 

So i started reading it a few months ago and stopped for some reason. Got back to reading it today and realised why i stoped reading it. Mc’s original sister. Can someone spoil me what happens to marie ie; mc’s original sister. Honestly if that bitch doesn’t die, change for the better, or written off of the story then i might just stop reading it. Saying that, I probably will since from what I’ve read, she’s probably gonna be on the of main antogonist isn’t she.
