He was fighting in his base state which equates him to mid-god class. She was a newly promotioned low-god class. Removing the time he spent training, we can assume that Igor has over 2 years of battle experience. Having fought with literal armies of God class entities, his victory should've been a landslide. But Aurelia herself is an Aryan that has awoken her ancestral memories for over sixty years. This means that thousands of years worth of magic spells and fighting techniques are in her head. So this allowed her to somewhat close the gap between the two of them. There's no doubt that if Igor even used Kaioken X2, he would've beat the absolute daylights out of her. But like we've seen with Baraquiel, he mostly wanted a good battle over winning which is why he didn't use his Kaioken for both of those fights.

Done

Thank you

Thank you for pointing that out

That's where you're wrong and I'll break it down. There's a big difference between KNOWING and SUSPECTING. To avoid spoilers, I won't go into too much detail. Shuri had lived for almost a decade without trouble from the Himejima. It is not wrong for the blonde to assume that nothing will happen for a few more years. Secondly, guess who talked him out of going after the Himejima? Thirdly, for those reading this review, although it counts as a spoiler, there is a happy ending and it's already been released in the later chapters.

Thank you. I will correct the mistake

You were coming along so well

"Satan class" was mentioned from Igor's perspective. That is because currently, Satan class is the term of classification he is most familiar with. But eventually, that should change as he mingles with Sun Wukong and his ilk.

That's an interesting take. Thanks

Thank you

I will assume that she means the saliva on her chopsticks has already touched the food. The only thing left untouched is the loaf of bread

Yes. Thank you

After more than 4 decades, it's nigh impossible for him to remember characters from a book. Maybe there'd be a higher chance if he had watched the anime but he certainly can't be expected to remember characters and plots he read from a book after that many decades passed.

Grammar error. Thank you for pointing it out. It has been fixed.

His father grew up in the mafia. His grandfather was probably no stranger to the world war. So when a world war 2 survivor also happens to be a gang leader, flowery words tend to be passed down. So it's not surprising if Igor picked up a word or two from his father's angry tirades. That and, Igor was practically alone for decades. You can notice how, before he started training, he didn't swear much. Even Ted commented on Igor swearing. But after he started training, he came out of the time chamber like a veteran sailor. We can only imagine that during his training, he must've frustrated himself enough times that cursing just became his normal way of speaking

I am not trying to be mysterious. I genuinely cannot say. I could say 'No' now, but then think the opposite three days later. That is why I cannot give you a proper a answer

Cannot say. There may or may not be.

His wish was for a time chamber that upon entry, halts the progress of his lifespan. Those were his only two wishes. Ancient Humans, in this context, can be seen as an evolution from cursed humans. Igor's goal, is to shatter the curse God placed upon humans and ascend into an ancient human that had a lifespan extending to a millennia. I hope that explains it.
