There's quite a few timelines and all of them have different standard deviations. I would call the OG timeline plus any timeline that had the empire having a rebellion the "Execution Timeline". Anyways, I'm not gonna spoil what happens because I really want people to read the series.
Robespierre is not a person you should really model your framework of beliefs on. He executed more people than the famine that led to the rebellion in the first place.
Look bro, I LOVED Nisekoi. I enjoyed it from beginning to end but bro you gotta admit there was like 30 chapters in between what you could actually call progress. Granted they had some great comedy but it didn't address all the locket and stuff.
I dunno, haven't read that manga for a long ass time.
One the many things I love about this timeline is that Marie actually feels like a proper shoujo heroine, she's got a bratty personality but she works hard and loves her friends and bounces off really well with the other members of the cast.
Ryoji is genuinely being awful here. He literally could've prevented all of this if he just showed a fraction of his power to her and fully lectured her. His passiveness is one of the reasons Kayoko became like that and if you're friends with someone, you should steer them away from making awful...
