I say let Lina freeze to death. It be a better end for her.

Yep, Lina is one of those type of girls. I been saying this on each chapter I have encounter her in this story. She is an attention seeking brat. She got a free ride in terms being the saint, but is not understanding that require to do work, she only wants to play by getting the hot guy, living a life of luxury. She is a modern girl, the worse type. She went after a known engaged guy, to win him she tried to become a Stern, which she wasn't allowed to become, she seduce the guy, nearly causing the mc and the guy to die, only to win the guy, and now she is clearly after the duke. She is a brat. Nothing more, nothing less. Right now she is trying to ruin the mc who has proven to be a humble girl who is performing her duties as a Stern, and even doing duties beyond a normal Stern would perform.

Lina, is you know what. I can stand this girl. No wonder she in the original storyline [you know before the whole mc insert] part got it easy to get her way. Simple answer, the villainess was a cruel girl, but the mc is in charge of that house and thus things are showing Lina's true nature. She is an attention seeking brat. She willing tried to seduce an engaged guy, and now she is aiming for the duke. She is noticing that the mc is getting nice stuff and wants it for herself, only proving herself to be greedy material seeking girl. She is proving to be the type of girl that you should never date, let alone marry.

I do not trust Lina. Now she feels sorry? With how she been acting? With her attempt to steal an engaged man? Because she did this by forcing herself to become a Stern, because she wanted the guy because she learned the mc was marrying the guy because she was a Stern, not the reason why.

Lina is a complete brat. There are no other words for her, other than an attention seeking brat.

Lina, doesn't understand what she did is wrong. She is not assimilating herself into her new home, the new cultures she finds herself in the middle of. Personally, I got a few choice words to describe her, anyone else can tell what she did was on purpose to win over a hot rich guy.

What an attention seeking girl. I can see that she wants the guy, who is likely very handsome and hot.

Marvel and DC comics crossover? That's a bit much. Better off going with one and then the other.

39 chapters spent on an escape. What a disappointment. You been dragging your story, using the System is bad choice as a support system for any story. After all, you spent 39 chapters on level up powers, but overall, it's lacking and taking too long.

So, she found Dexter before his encounter with the Red Ring. I felt sorry, for that poor cat. As I am a cat person.

Biggest mistake to allow him to spill the beans about Izuku having that Quirk, and the fact that All Might is not asking why. Makes it even worse.

Why did you allow your character to spill the beans that he knew how Izuku got his Quirk.

A super weapon, with the force of a nuke with no radiation is not a bad thing. If anything, it can reduce the death rate among the androids. Find a target that is too dangerous, take it out from orbit.

Great film, but it would not have been the culture I would have wanted to be reborn into. Of all the Ancient Greek City-States, the Spartan was the worse of the worse, they were focus on military only, nothing else, and that didn't stop Alexander the Great.

While Spartan Army is an advance fighting force for the classical era, it's also the most brutal for that era. Their training was brutal since childhood, but that was basically all it was. Anything not perfect was killed, kids with any deform features were automatically killed. A Spartan graduating into adulthood had to track down and murder a slave. The primary reason why they were successful in 300 was their location of fighting, as their enemy was forced to go down a tight path, which eventually they loss as the enemy was able to get around this defense. If a classical army was needed, then the Spartans would not be my first choice. There were the armies of Ancient China of their various kingdoms, the Roman Empire, and many others that would have been a better choice.

Adding to much can kill a story, basically that suit given by Mark to Tony

So, jumping between dimensions... I'm not sure what to feel about this plot idea. It seems corny to say the least, the point I want to skip at lot of stuff, which is actually a bad thing for author, as readers' losing interest is not a good thing.

He is full of himself. Even if he's not a believer, the way he acted lacks empathy because he has the power.

Okay from what I am reading, the structure of the story is well made. Some people write chapters for their stories, but never truly put in the effort into the storyline structure. Basically... "He wrote this." Author spoke, instead of you including background information of what your characters are doing or their reactions to certain actions or speech. I view that as a sign of a good writer with a promising writing style.

The chapters seem to have half the effort put into them. Which is confusing and causes a desire to skip, which is not a good thing.
